... composites are shown in Fig. 8.4 . Two types of polymer matrices are shown: thermosets and thermoplastics. A thermoset starts as a low-viscosity resin that reacts and cures during processing, forming an intractable solid, while a thermoplastic is a high-viscosity resin that is processed by heating it above...
