How Carbon Fiber Tubes Are Made

Carbon fiber tubes are ideal for both the hobbyist and industry professional. Using the rigidity of the carbon fibers, an extremely stiff yet lightweight tubular structure can be used in a wide range of applications. Carbon fiber tubes can replace steel, but more often than not, it is replacing aluminum. In many instances, a carbon fiber tube can weigh 1/3rd of an aluminum tube and still have the same or better strength characteristics. Because of this, carbon fiber reinforced tubes are often found in applications lightweight is crucial, like aerospace, race cars, and recreational sports. The most common carbon fiber tubular profile shapes are squares, rectangles, and circular. The rectangular and square profiles are commonly referred to as a box beam. Carbon fiber box beams provide excellent rigidity to a structure and simulate two parallel I-beams. Carbon Fiber Tube Applications Any application where weight is crucial, switching to carbon fiber will be beneficial. The following are some of the most common uses of carbon fiber tubes: Aerospace beams and sparsFormula 1 structural componentsArrow shaftsBicycle tubesKayak paddles Manufacturing Carbon Fiber Tubes Hollow composite structures can be difficult to manufacture. This is because pressure needs to be applied to both in internal and the external side of the laminate. More often than not, carbon fiber tubes with a continuous profile are manufactured by either pultrusion or filament winding. Pultruded tubes are by far the most cost-effective method of manufacturing continuous composite profiles. When pultruding a hollow tube, a floating mandrel is required. A chromed steel rod is firmly affixed in place on the side of the die where the raw material enters. The mounting hardware is far enough away that does not interfere with the impregnated fiber as it enters the die. The space between the mandrel and the die will determine the wall thickness of the carbon fiber tube. Pultruding carbon fiber tubes allow for the production of tubing of virtually any length. Transportation of the tube is generally the restriction on length. In pultrusion, most of the fiber will run the direction of the tube. This creates a tube with a tremendous about of stiffness, but not much hoop strength, or cross-directional strength. Filament Wound Carbon Fiber Tubes For increased strength and properties in all directions, filament winding is an effective method in manufacturing carbon fiber tubes. Filament wound tubes are cost effective and have excellent properties, however, the largest limitation is based on the length of the winding machine. Other Manufacturing Processes Pultrusion and filament winding, although the most common, is not the only way to manufacture carbon fiber tubes. Bladder molding, compression molding, vacuum infusion, and autoclave processing are all methods to manufacture carbon fiber tubes. Each has its own advantage and disadvantage as well.

The Antagonist As A Human Competitor - 970 Words

The antagonist is the opposing power in a story, this can be a human competitor, or it could be non-human, like an animal or something less touchable, like fear, flood, and material thing is some stories. Protagonist and antagonist are two important characters of the story and they cannot exist without each other.

Events takes place according to the wishes of the writer, moving from one setting or event to another to overcome the conflict provided by the antagonist against protagonist who is seeking the goals of the resolution. The struggle between the two reaches to a highest emotional stage, when the events and actions at a crucial point called the climax. This is the point of no return for both the protagonist and antagonist as the story or narrative about to reach its logical end.

Jurassic Park Essay Summary Example For Students

Jurassic Park Essay Summary Jurassic Park, by Michael Crichton is an incredible book, which describes genetic engineering and the creation of an extinct species. Michael Crichton uses marvelous detail throughout the book. As great as the book is, it is not that appropriate for children who are 15 and under because of the gore, description, violence, and obscenities through out the story. Jurassic Park is a great book. Michael Crichton uses such descriptive detail, that you could picture everything that is going on like you are watching a movie.There is not one moment of boredom in the book. Every second something new is happening or another problem in the park occurs. These things make the book very hard to put down. Jurassic Park is a marvelous book with a great plot. Yet, later it becomes inappropriate for children.The first thing that makes Jurassic Park not appropriate for young children is that it is amazingly gory. Michael Crichton describes people and animals being killed in a very descriptive manner. When Dennis Nedry, the computer programmer, was on his way to the dock to deliver frozen dinosaurs embryos to another genetic engineering company, a concrete barrier was in his way. He got out of his car and started to run into the jungle. When he reached the jungle river, he heard a soft hooting cry. When he turned around, he saw a dilophasaur standing directly in front of him. Suddenly, the dilophasaur spit at him. The novel refers to this by saying, Nedryfelt an excruciating pain in his eyes, stabbing like spikes in the back of his skull. It then says, Slowly the realization came to him. He was blindThen there was a new searing pain like a fiery knife in his belly, and then Nedry stumbledthen there was a new pain on both sides of his head. The pain grew worse, and as he was lifted to his feet he knew the dinosaur had his head in its jaws, and the horror of that realization was followed by a final wish, that it would all be ended soon (p. 196). This demonstrates the horrifying description in the book. Another gory scene was when Ed Regis was swallowed by the juvenile T-rex. The book describes this by saying, Regis yelled, and the juvenile ducked his head, and Regis began to scream. No words just a high pitch scream. The scream cut off abruptly, and when the juvenile lifted his head, Grant saw ragged flesh in his jaws (page 216). These wer e only two very gory parts out of many. Jurassic Park also has many violent and obscene scenes. Other than the two above, there are many more. One of them was when Henry Wu, the man who was in charge of the making of dinosaurs, was standing out side the lodge when a velociraptor jumped the roof and tore Wu open. The book refers to this by saying, Wu was yanked bodily out of the doorWu was lying on his back already torn open by the big clawthe raptor was tugging at Wus intestines even though Wu was still alive, still feebly reaching up to push the big head away (page 334) This was probably one of the goriest scenes. Even with all these deaths, and more, there were still lots of injuries. Just about every character was injured in some way. As one could see, Jurassic Park is very violent and gory. Jurassic Park is also obscene. The language used is definitely inappropriate for children our age. They use foul language throughout the book. At one point, Tim Murphy, the 11 year-old boy, c urses four times in one line. He does this when the car falls over the cliff and is stuck in the branches of the trees. Jurassic Park ended up becoming Michael Crichtons most successful novel, and a New York Times Best seller. The book was so successful in fact, that Steven Spielberg ended up making a movie about it three years later. Overall, Jurassic Park is a spectacular novel that uses great detail. Even though it was such a great book, there is a lot of violence and gore. Because of all this violence, this book is not appropriate for children under 15. .u9b9201c8aa397bad28c42b39c949e3e7 , .u9b9201c8aa397bad28c42b39c949e3e7 .postImageUrl , .u9b9201c8aa397bad28c42b39c949e3e7 .centered-text-area { min-height: 80px; position: relative; } .u9b9201c8aa397bad28c42b39c949e3e7 , .u9b9201c8aa397bad28c42b39c949e3e7:hover , .u9b9201c8aa397bad28c42b39c949e3e7:visited , .u9b9201c8aa397bad28c42b39c949e3e7:active { border:0!important; } .u9b9201c8aa397bad28c42b39c949e3e7 .clearfix:after { content: ""; display: table; clear: both; } .u9b9201c8aa397bad28c42b39c949e3e7 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u9b9201c8aa397bad28c42b39c949e3e7:active , .u9b9201c8aa397bad28c42b39c949e3e7:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u9b9201c8aa397bad28c42b39c949e3e7 .centered-text-area { width: 100%; position: relative ; } .u9b9201c8aa397bad28c42b39c949e3e7 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u9b9201c8aa397bad28c42b39c949e3e7 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u9b9201c8aa397bad28c42b39c949e3e7 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u9b9201c8aa397bad28c42b39c949e3e7:hover .ctaButton { background-color: #34495E!important; } .u9b9201c8aa397bad28c42b39c949e3e7 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u9b9201c8aa397bad28c42b39c949e3e7 .u9b9201c8aa397bad28c42b39c949e3e7-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u9b9201c8aa397bad28c42b39c949e3e7:after { content: ""; display: block; clear: both; } READ: Sport For Babies Essay

This essay will be focusing on the 2008 film Wall- Essays

This essay will be focusing on the 2008 film Wall-E released by Pixar animation studios. This essay will be reviewing and discussing the political side of the film, as well as looking at any other hidden messages. These include the environmental messages, nostalgia and dystopia. As well as reviewing the film itself to see if there is any pattern forming to link all the elements together. Wall-e was released in 2008 by Disney Pixar studios, and featured voices such as Ben Burtt as Wall-e and Elissa Knight as Eve, it also features Sigourney Weaver. Wall-e is a computer generated animated feature created on Pixars own software Renderman. Wall-e is based on a small waste collecting robot who unwillingly embarks on a space journey that decides the fate of mankind. Wall-E stands for Waste Allocation Load Lifter- Earth class, and Eve stands for Extra-terrestrial Vegetative Extractor. In a not so distant future, mankind has left earth because of the state it has become. Completely over run by rubbish that towers over the tallest skyscraper, all the rubbish seems to be the product of a multi-million dollar company, Buy N Large. One robot has been left behind to clean up the mess, Wall-E, one of the last living things on the planet, as well as his pet, a cockroach. Wall-E is infatuated with the objects left behind by people, enriched with mankinds history and a tape of show tunes he found. One day he follows a light hoping to add it to his collection, unbeknownst to him, its actually part of the landing process for a ship carrying the Eve probe. Eve has been sent to find evidence of life being sustainable once again on earth. Wall-E falls in love with Eve, and rescues her from a dust storm, and takes her back to where he lives. He shows Eve all of his trinkets, including his latest find, a plant. This plant is what Eve has gone to earth for, she takes the plant from Wall-E and then shuts down, with just a green plant symbol on her front blinking. Wall-E isnt sure what has happened to her, and thinks that her battery could just be running low, so he takes her outside to charge in the sun, and makes many attempts to wake her up. When that fails he protects her from the various weather conditions, until the ship comes back to retrieve her. Something Wall-E didnt expect, so he hitches a ride on the back of the ship, to the axiom. The axiom is the space cruise ship that is carrying all the people of earth who evacuated over 700 years ago; they were only supposed to be aboard for 5 years whilst the robots cleaned up the planet. The people of earth are all living a secluded life, never walking anywhere, constantly in their floating chairs, which give them full access to TV and social networking. They never eat solid foods, they drink it all from a cup and a straw, and theyve all become overweight due to bone loss, and lack of exercise. Any exercise t hey do is done through a robot that they control on their screens. When Eve manages to bring the plant back to the pilot, the auto pilot, whos acting upon instructions given to him 700 years ago, stages a mutiny, so that nobody will be able to return to earth. Its with the help of Wall-E that the people aboard the axiom realise that they need to go back to earth to save it an end the 5 year cruise. In the book The films of Pixar animation studio they point out that the film looks at what it is to be human this is because in the film Wall-E, all the humans that left earth are now surviving on the axiom, which is a space cruise ship used as a home for the rest of humankind. All the people aboard the axiom however seem to be living a secluded life, they never interact with anybody face to face, or walk anywhere, and they are constantly eating fast food. They live such a secluded life that when they are introduced to a new colour for their suits,
