WebThermosets are a popular polymer matrix material for fibre reinforced composites. Common examples include polyesters and epoxies. They are the most predominant type of matrix system, particularly in the aerospace market segment. A thermoset polymer matrix is a synthetic polymer reinforcement where polymers act as binder or matrix to secure in place incorporated particulates, fibres or other reinforcements. They were first developed for structural applications, such as glass-reinforced plastic radar domes on aircraft and graphite-epoxy payload bay doors on the Space Shuttle. They were first used after World War II, and continuing research has led to an increased range of thermoset …
