Answer to Question 1

The very short fiber composites are made with thermoplastic matrices because of the low cost of manufacture if traditional thermoplastic manufacturing methods are used. Furthermore, the applications for these materials are generally well suited to the thermoplastic composites, with additional strength or stiffness by the fibers. On the other hand, composites with long fibers are made from thermoset because of the difficulty of wetting-out the fibers. The additional stiffness and higher temperature capabilities of thermosets also contribute to their use.

Answer to Question 2

Composites are lighter weight at equivalent strength and stiffness. Composites can be made so that their mechanical properties are directional and can be tailored to a specific application. Composite materials do not corrode.
