A non-woven carbon fiber reinforced thermoplastic (CFRTP) composite object is formed by the variable frequency microwave (VFM) irradiation of a mixed fiber sheet of thermoplastic fibers, carbon fibers and wavy carbon nanotubes (CNTs). The mixed fiber sheets are prepared from a slurry of the thermoplastic fibers, carbon fibers, and wavy CNTs such that the wavy CNTs contact the carbon fibers and thermoplastic fibers. Upon irradiation with VFM radiation, the wavy CNTs generate heat and transfer the heat to the thermoplastic fibers, causing melting of the thermoplastic to form the matrix of the CFRTP composite object. The mixed fiber sheets can be combined alone or with other sheets to form laminar composites that are molded into objects and heated by VFM irradiation.

A monofilament made of glass-resin composite has improved properties in compression, in particular at high temperature, and comprises glass filaments embedded in a crosslinked resin. The glass transition temperature of the resin is equal to or greater than 190° C. The elongation at break of the monofilament, measured at 23° C., is equal to or greater than 4.0%. The initial tensile modulus of the monofilament, measured at 23° C., is greater than 35 GPa. The real part of the complex modulus of the monofilament, measured at 190° C. by the DMTA method, is greater than 30 GPa. Pneumatic or non-pneumatic tires are reinforced with such a composite monofilament.

A material susceptible to dielectric heating has a base polymeric thermoplastic material (1) and a dielectric heating susceptor (2, 3) which increases susceptibility to heating by irradiation with electromagnetic, for example RF or microwave, radiation. The dielectric heating susceptor has a polymeric material (2) such as PVDF which is different from the base polymeric material and has a higher dielectric loss factor than the base polymeric material. The dielectric heating susceptor also comprises electrically polarisable entities such as carbon black dispersed within the base polymeric material without forming a conductive network. The two susceptor materials in combination with the base polymer are particularly effective together at improving susceptibility to electromagnetic radiation heating of the whole material.
