  • Composite material having a fibrous reinforcement and matrix obtained by the polymerization of acrylic monomers and its production
    Patent number: 5650462
    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.

  • Method of forming a fibrous structure composite ceramic material and material thus obtained
    Patent number: 5024979
    Abstract: 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:(a) said fibrous support is impregnated with a polymerization catalyst for an organometallic precursor of said ceramic matrix;(b) said fibrous support impregnated with said polymerization catalyst is placed in contact with said organometallic precursor;(c) said organometallic precursor is polymerized, and(d) said organometallic precursor is pyrolysed so as to obtain said matrix.
