An example of the second category is the bio-composite poly-epsilon-caprolactone and hydroxyapatite (PCL/HA) bone scaffold fabricated using SLS, with the addition of HA to enhance the strength and biocompatibility of PCL .

The First Generation (1940s): Glass Fiber Reinforced Polymers (GFRPs) While it seems obvious that making whole components (wings, nose cones, helicopter rotors, etc.) out of these high strength materials would be the answer, this was not the solution.

In contrast to metallic alloys, each material retains its separate chemical, physical, and mechanical properties. the two constituents are a reinforcement and a matrix. the main advantages of composite ma-terials are their high strength and stiffness, com-

Reinforced plastics, which are relatively inexpensive, typically consist of poly-ester resins reinforced with low-stiffness glass fibers (E-glass). They have been in use for 30 to 40 years in applications such as boat hulls, cor-

1. Classification of materials

Another of these technologically important materials is the “carbon fiber reinforced polymer” (or “CFRP”) composite—carbon fibers that are embedded within a polymer. These materials are stiffer and stronger than the glass fiber-reinforced materials (Figures 1.2 and 1.3), yet they are more expensive.
