ABSTRACT:
The invention relates to the production of composite materials having a fibrous reinforcement and matrix obtained by the polymerization of acrylic monomers.
These acrylic monomers are tetraacrylates of formula: ##STR1## in which R.sup.1 and R.sup.2, which can be the same or different, represent H or CH.sub.3, and Z is a divalent group having 1 or 2 aromatic or aliphatic cycles.
For example, Z is a group derived from bisphenol A and R.sup.1 and R.sup.2 represent H.
The composite materials can be prepared by injection moulding.
