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.

Composite material having a fibrous reinforcement and matrix obtained by

A method is provided for forming a composite ceramic material, in which a fibrous structure is first of all formed which is then embedded in the material of a ceramic matrix. To introduce said matrix into said structure, the following succession of operations is carried out:
