COMPOSITE MATERIAL COMPRISING FIBROUS REINFORCEMENT AND MATRIX OBTAINED BY POLYMERIZATION OF ACRYLIC MONOMER AND ITSPRODUCTION

摘要

The composite material comprises (a) a fibrous reinforcement and (b) a matrix formed by polymerisation of a compsn. hardenable by ionisation by means of X-rays or electrons, and consisting of a mixt. of (I) a tetraacrylate of formula (IV) with a diacrylate and/or triacrylate of formula (II) or (III) a monofunctional acrylic diluent. R<1>, R<2> = H or Me; Z = bivalent gp. carrying 1 or 2 aromatic or aliphatic rings; R<6> = H or -C(O)-C(R<1>)=CH2.
