A thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin. Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a is not necessarily to be applied externally. It is often generated by the reaction of the resin. There are polymer matrix composites (PMC's), ceramic matrix composites (CMC's), and metal matrix composites (MMC's). Materials within these categories are often called "advanced" if they combine the properties of high strength and high stiffness, low weight, corrosion resistance, and in some cases special electrical properties.

The thermal protection system for the underside of the vehicle, comprising the nose, leading edges and lower surface of the wing, were designed and made by Herakles using a ceramic matrix composite (CMC), carbon/silicon-carbide (C/SiC). These components will function as the vehicle's heat shield during its atmospheric reentry.

The matrix material experiences a melding event, after which the part shape is essentially set. Depending upon the nature of the matrix material, this melding event can occur in various ways such as chemical polymerization for a thermoset polymer matrix, or solidification from the melted state for a thermoplastic polymer matrix composite.

Composite coatings often present a higher corrosion resistance compared with the pure metallic coatings. The improved properties are not directly related to the intrinsic properties of the incorporated particles, but to the microstructural modifications of the metal matrix due to the codeposition of ultrafine, mainly nanometric, particles.

Polymer matrix composites are most advanced composites; these composites have different types of fibers (natural and synthetic) as reinforced material in different types of polymers such as thermoplastic or thermoset polymers, which can mold in different shapes and sizes, and make different types of fashioned materials [49,50].
