Composite used in aircraft manufacturing for small scale industries INTRODUCTION In the revolution of high technology of aircraft industrial world has came because of composite materials. It is due to the main property of highly effective and efficient material which is leads to advanced ones. In world of business, customer satisfaction is the most important thing which has become a great need now a day. As innovation going on in the field of composites, the demand of these materials has increased because of higher lighter in weight, less expensive, stronger, durable which helped aircraft industries to achieve their respective goals. In the field of research and development, the scientist has proved that the use of composite materials in the aircraft has made them efficient which also further used in the field of defense industries. The composite materials are made from two or more constituent materials with respective different chemical and physical properties, if we mix these materials with each other then we will get a different material with respective different properties. This kind of material can be used for more purposes such as flexibility, strength, durability, and so on. The composite materials has become famous in the middle of the nineteenth century in the manufacturing of aircraft field. Comparatively, the fiber glass material was used at great quantity because of number of characteristics such as light weight, less expensive, lesser corrosive, and soShow MoreRelatedReduction of Part Counts and Composite Materials for Aircraft Structures626 Words   |  3 PagesComposite materials comprise significantly greater percentages of airframe structural materials used throughout the aerospace manufacturing process. This increased usage has led many individuals within the Air Force (AF) community and Department of Defense (DoD) leaders to restudy the life cycle cost (LCC) models used to estimate the costs for most weapon systems. A series of composite affordability initiatives (CAI) have culminated in significant evidence over the last three decades which aids inRead MoreWhy Are Composites Better Than The Use Of Traditional Materials?1130 Words   |  5 PagesIntroduction Since the 1970’s, composite materials have been used in aviation in the form of composite aircraft, and the use of composites has only been expanding. Boeing aircraft from the past, like the 747 circa 1968, were generally made up of only 1% of composite material, whereas relatively newer aircraft, like the 777, which began its service life in 1995, jumped to 11% composites. By 2011, and the introduction of the 787 Dreamliner, the percentage of composites had risen to an astounding 50%Read MoreComposite Materials : How They Are Made And Used As Aircraft Parts1590 Words   |  7 PagesComposite Materials: How They Are Made and Used as Aircraft Parts.

In early aircrafts, such as the Wright Flyer, were constructed from Stika spruce, which is a natural type of fibrous composite material. This material gave the aircraft many issues, one of them being fungal rot which then imposing a change in the design of aircraft material. This then brought the introduction of other alternate materials; such as aluminiumRead MoreDesign Aspects Of The Composite Replacing Metal Parts1677 Words   |  7 PagesSince the first aircraft was developed for flight, people have ha d a goal to improve the aircraft’s physical applications and production of the aircraft more profitable.

With these improvements aircraft would require less

The Problem Of Childhood Obesity - 2817 Words

According to The State of Obesity (Trust for America’s Health, 2014), in the United States today, 31.8% of children are obese or overweight, 16.9% of that number are obese. Nurses are at the forefront of promoting health, so what can they do to eradicate this prevalent disease? Research by Ogden, Carroll, Kit, Flegal (as cited in the Centers for Disease Control and Prevention, 2014) states that from 1980 to 2012, the percentage of overweight or obese children more than doubled, totaling to greater than one third of all children and adolescents as overweight or obese. Childhood obesity is an epidemic that is sweeping the nation and becoming a severe problem. Besides the obvious risks of cardiovascular disease, bone and joint issues, low†¦show more content†¦It is crucial to stop obesity at its root because of the difficulty keeping weight off after losing it. A recent study has shown that there is a biological reason for that problem that many people have had. Once a person has gained weight, it is hard to lose it, but much harder to stop from gaining much of it back. The study shows that this problem is not willpower; it is hormones. Body weight is regulated by hormones released by the pancreas, gastrointestinal tract, and hypothalamus. These regulate how hungry we are versus how much energy we use. A 2011 study published in the New England Journal of Medicine found that subjects’ hormone levels, specifically leptin and ghrelin, after they had lost weight were not normal for their new weight; they did not adjust properly for the new weight. In fact, not only that, but the hormones were triggering hunger and causing the storing of fat. When a person who has never gained and lost weight might use fifteen calories to ride a bicycle for a certain amount of time, a person who has lost weight might only expend five calories. In other words, calories that the subjects took in were not being used as they should be because the body was storing t hem as fat instead. This was their bodies’ attempt to regain the weight and return to what the body thought of as normal. This landmark finding has begun to make doctors, scientists, and researchers think differently about weight regain. Often, it

The Silver Linings Playbook Chapter 6 Free Essays

The Concrete Doughnut I notice that my father waits until the game is just about to begin before he comes into the family room. It is only preseason, so we do not engage in any of the regular-season game-day rituals, but Dad has put on his number 5 McNabb jersey and now sits on the edge of the couch, ready to jump out of his seat. He nods at my brother solemnly but completely ignores me, even after I heard my mother say, â€Å"Please, just try to talk to Pat† when they were arguing in the kitchen. We will write a custom essay sample on The Silver Linings Playbook Chapter 6 or any similar topic only for you Order Now Mom puts the food on folding tables, takes a seat next to Jake, and we all start to eat. The food is excellent, but I am the only one to say so. Mom seems happy to get the compliment, saying, â€Å"Are you sure it’s all right?† like she does, because she is modest when it comes to cooking, even though she is a great cook. â€Å"What do you think the Birds will do this year, Dad?† Jake asks. â€Å"Eight and eight,† my dad answers pessimistically, like he always does at the beginning of every NFL season. â€Å"Eleven and five,† my brother says, to which my father shakes his head and blows air through his teeth. â€Å"Eleven and five?† my brother asks me, and I nod because I am optimistic, and winning eleven games would most likely put the Eagles in the play-offs. Since we have season tickets, I know we are assured play-off tickets should the Birds earn a home game, and there’s nothing better than an Eagles play-off game. Now, I admit that I have not been keeping up with the Birds in the off-season, but when the starting lineups are announced, I am really surprised that many of my favorite players are no longer on the team. Duce Staley. Hugh Douglas. James Thrash. Corey Simon. All gone. I want to ask, â€Å"When? Why?† but don’t, fearing my father and brother will think I am not a true fan anymore, which they said would happen when I first moved to Baltimore with Nikki and gave up my season ticket. To my surprise, the Birds are also not playing in Veterans Stadium, but at Lincoln Financial Field, just like Jake had said. Somehow they have built an entire stadium since last season, and I must have missed all the hype because I was stuck in the bad place. Still, something does not really seem right to me. â€Å"Where is Lincoln Financial Field?† I try to ask nonchalantly when the commercials come on after the first series. My father turns his head and stares at me but does not answer my question. He hates me. He looks repulsed, like it is a chore to sit in the family room watching the game with his mentally messed-up son. â€Å"It’s in South Philadelphia, just like all the other stadiums,† my brother says too quickly. â€Å"Good crabby snacks, Mom.† â€Å"Can you see Lincoln Financial Field from the Vet?† I ask. â€Å"The Vet’s gone,† Jake says. â€Å"Gone?† I ask. â€Å"What do you mean, gone?† â€Å"March 21, 2004. Seven a.m. It fell like a house of cards,† my father says without looking at me, just before sucking an orange piece of meat from a chicken bone. â€Å"Over two years ago.† â€Å"What? I was at the Vet just last †¦Ã¢â‚¬  I pause because I start to feel a little dizzy and nauseous. â€Å"What year did you just say?† My father opens his mouth to speak, but my mother cuts him off, saying, â€Å"A lot has changed since you were away.† Still, I refuse to believe the Vet is gone, even after Jake retrieves his laptop from his car and shows me a downloaded video of the Vet being imploded. Veterans Stadium – which we used to call the concrete doughnut – falls like a circle of dominoes, gray dust fills the screen, and it breaks my heart to see that place crumble, even though I suspect that what I am viewing is a computergenerated trick. When I was a boy, my father took me to many Phillies games at the Vet, and of course there were all of the Eagles games with Jake, so it is hard to believe such a big monument to my childhood could be destroyed while I was in the bad place. The video ends, and I ask my mother if I can talk to her in the other room. â€Å"What’s wrong?† she says when we reach the kitchen. â€Å"Dr. Patel said that my new medication might make me hallucinate.† â€Å"Okay.† â€Å"I think I just saw Veterans Stadium demolished on Jake’s computer.† â€Å"Honey, you did. It was demolished over two years ago.† â€Å"What year is it?† She hesitates, and then says, â€Å"Two thousand and six.† That would make me thirty-four. Apart time would have been in progress for four years. Impossible, I think. â€Å"How do I know I am not hallucinating right now? How do I know you’re not a hallucination? You’re all hallucinations! All of you!† I realize I am screaming, but I can’t help it. Mom shakes her head, tries to touch my cheek, but I swat her hand away and she starts crying again. â€Å"How long was I in the bad place? How long? Tell me!† â€Å"What’s going on in there?† my father yells. â€Å"We’re trying to watch the game!† â€Å"Shhhh!† my mother says through tears. â€Å"How long?† I yell. â€Å"Tell him, Jeanie! Go ahead! He’s going to find out sooner or later!† my father yells from the family room. â€Å"Tell him!† I grab my mother’s shoulders, shake her so her head wobbles all over, and yell, â€Å"How long?† â€Å"Almost four years,† Jake says. I look back over my shoulder, and my brother is in the kitchen doorway. â€Å"Now let go of Mom.† â€Å"Four years?† I laugh and let go of my mother’s shoulders. She covers her mouth with her hands, and her eyes are full of pity and tears. â€Å"Why are you guys playing jokes on – â€Å" I hear my mother scream, I feel the back of my head hit the refrigerator, and then my mind goes blank.
