A composite material and method of producing a composite material for use in fabrication, building and construction is disclosed. A composition as disclosed herein comprises a high proportion of particulate waste material dispersed in a matrix of thermoplastic polymer and wax. A method of producing a composite material comprises melt mixing thermoplastic polymer and wax with a particulate material, thereby dispersing the particulate material in a melt mixture of the composite material.

Provided herein according to some embodiments is a dual cure stereolithography resin that includes thermoplastic particles, which thermoplastic particles are insoluble in the resin and insoluble during a first, light, cure in which an intermediate object is produced, but then dissolve or swell in the intermediate object during the second, heat, cure.

Provided herein according to some embodiments is a dual cure stereolithography resin that includes a Diels-Alder adduct, which adduct is light polymerizable in the first, light, cure to produce an intermediate object, and on heating the intermediate object yields a bis-maleimide that can further react and/or polymerize during the second, heat, cure.

An insert member (100) heated by a heating device (13) is conveyed, by means of a conveyance device (12), into a mold (51). Next, shaping is performed on the insert member (100) inside the mold (51), with the mold (51) being open by a minute distance. A molding material (91) is injected into the mold (51) and pressed while closing the mold (51) which has been open by the minute distance to thereby mold a molded article (80) including the insert member (100).

The invention relates to a method for impregnating at least one fibre bundle (11) with a high-viscosity plastics material (13), said method comprising the following steps: •—providing at least one fibre bundle (11) for impregnation, formed of a multiplicity of continuous fibres, and providing a plastics material (13), melted at a mandated operating temperature and of high viscosity, and •—impregnating the fibre bundle (11) with the plastics material (13), by guiding the fibre bundle for impregnation continuously through an impregnation cavity (12), filled with the melted plastics material (13), •—where during impregnation of the fibre bundle, the melted plastics material within the impregnation cavity is contacted with a surface (15) of at least one oscillation generator (14) in such a way that sonic energy is introduced by said oscillation generator into the melted high-viscosity plastics material in the impregnation cavity.

Disclosed is a fiber-reinforced resin composite body (1) including: a thermosetting resin (2); a plurality of reinforcing fiber layers (4) stacked in the thermosetting resin (2); and a thermoplastic resin (5) dispersed in a form of particles in the thermosetting resin (2) between the plurality of reinforcing fiber layers (4).
