... of matrices is that they are reactive (thermosets) and nonreactive (thermoplastics) polymers. Most thermoplastic-matrix composites are developed with their polymerization complete. As a result, thermoplastic fiber-reinforced composites are generally more difficult to produce due to high viscosity resulting...
