LIQUID (METH)ACRYLIC SYRUP FOR IMPREGNATING A FIBROUS SUBSTRATE, METHOD OF IMPREGNATING A FIBROUS SUBSTRATE, COMPOSITE MATERIAL OBTAINED FOLLOWING POLYMERISATION OF THE PRE-IMPREGNATED SUBSTRATE

摘要

The invention concerns a liquid (meth)acrylic syrup for impregnating a fibrous substrate. The invention concerns in particular a viscous liquid syrup primarily containing methacrylic or acrylic components. The invention also concerns a method of producing this syrup. The invention further concerns a method of impregnating a fibrous substrate or long fibres with the viscous liquid syrup. The invention also concerns a fibrous substrate pre-impregnated with the syrup which can be used for manufacturing mechanical or structured products or parts. The invention further concerns a method of manufacturing mechanical or structured parts or articles and three-dimensional mechanical or structured parts obtained by this method. The invention is used for producing mechanical parts or structural elements made of fireproof thermoplastic composite material.
