introduction
I AM GOING TO DO A PRESENTATION ON SPORTS PERFORMANCE RELATED THINGS. AND I AM GOING TO TELL YOU ABOUT THE DIFFERENT KINDS OF COMPOSITE MATERIALS. I AM GOING TO TELL YOU THE ADVANTAGES AND DISADVANTAGES OF COMPOSITE MATERIALS. ALSO THE PEOPLE THAT WORK WITH COMPOSITE MATERIALS.
TYPES OF COMPOSITE MATERIALS
THERE ARE VARIOUS TYPES OF COMPOSITE MATERIALS AND HERE ARE TWO EXAMPLES:- CARBON FIBRE AND FIBRE GLASS.
CARBON FIBRES-THESE ARE USED IN THE MAKING OF SPORTS EQUIPMENT.
FIBRE GLASS:- IS USED IN THE MAKING OF RACING CARS AND OTHER SUCH VEHICLES.
Engineer
Engineers apply technology to build things
When it comes to building composites just about all engineers disciplines can be involved. Specific engineering tasks include, stress analysis, structural designs, materials processing, control systems, industrial processes, testing and more Engineers must have an under graduate degree and many have master degrees. Doctorates are less common.
Scientists
At the risk of oversimplifying things, Scientists develop the technologies that engineers apply. In general, then, they are more involved in basic research such as material development and structural theory. Of course, many engineers perform research, and many scientists work on engineering applications. Most scientistshave doctorates; fewer stop at a Masters or Bachelors.
Technician
At the risk of over simplifying again, again technicians are people who do most of the hands-on work. They lay up the composites, do the machining, and produce the drawings. Technicians develop highly specialised skills, most of which are learned on the job. A vocational background or an associates degree is common.
Faculty (research)
University faculty members can be either engineers or scientists, and the all most exclusively hold doctoral degrees. In contrasts to industry engineers, university professors in engineering departments focus more on research than on manufacture of a specific product. The research, however, might be orientated towards industry interests such as manufacturing processes.
Recycling
An important usage of concern involves the materials entire lifecycle, as carbon fibre reinforced plastics have an almost infinite lifetime. Some companies are succeeding in recycling this carbon fibre. The recycling strategy centres on milling, compounding or shredding the reclaimed carbon fibre, and finding use for this end product in various industrial applications (including carbon fibres applications less stringent than those required by, say, the aerospace industry). It is also commonly used in electronics, such as laptops, to lower the weight load and to improve durability.
