When it comes to composites, there is a long list of benefits compared to many other materials. It is because of these benefits that many industries have found uses for them in order to solve complex problems. Composites continue to enable technology. Below are some of the main benefits when using composites.
Lightweight: Composites significantly reduce weight while still maintaining desired strength. The density of a carbon fiber / epoxy laminate is 5 times lighter than steel.
High Stiffness: Some carbon fiber is 3 times stiffer than steel and 8 times that of aluminum. This can be valuable when trying to build long reach robotic arms. But when you compare the stiffness with relation to the weight it is 10 times stiffer than most metals.
Tailor Strength and Stiffness: Parts can be designed to be stronger or stiffer in the directions and location necessary to optimize performance. This is all done by fiber orientation.
Elastic: Fiber reinforced materials have excellent elastic properties unlike many metals which yield or dent.
Non-Conductive: Fiberglass Composites are non-conductive in regards to electrical and thermal energy. There function well at cryogenic temperatures.
Fatigue Properties: Composites have great fatigue properties compared to many other materials.
Transparency to Radio Frequencies: Fiberglass is a commonly used in the aerospace industry on radomes and antennas.
