Composite comprising a matrix material made of an amorphous polyamide and use thereof

A composite which comprises a matrix material made of a fibre-containing material and an amorphous polyamide with a glass transition temperature (Tg) of at least 180° C. formed from

• a) 10 to 50% by mol of at least one aromatic dicarboxylic acid selected from the group consisting of terephthalic acid, isophthalic acid and naphthalenedicarboxylic acid,
• b) 0 to 40% by mol of at least one aliphatic dicarboxylic acid,
• c) 0 to 10% by mol of at least one dimeric fatty acid,
• d) 17 to 50% by mol of at least one cycloaliphatic diamine selected from the group consisting of alkyl-substituted bis(4-aminocyclohexyl)methanes and alkyl-substituted bis(4-aminocyclohexyl)propanes, and
• e) 0 to 33% by mol of at least one further diamine which is different from component (d) and
• f) 0 to 30% by mol of at least one lactam or of an α,ω-amino acid,
• the sum of the molar proportions of a) to e) adding up to 100% by mol and the at least one lactam or the α,ω-amino acid being comprised in a concentration of up to 30% by mol, relative to the sum of the molar proportions of all the diamines and of all the dicarboxylic acids,
• wherein the fibre-containing material is selected from the group consisting of woven fabrics, fleeces, knitted fabrics, crocheted fabrics, layered fabrics, and combinations thereof;
• and
• wherein the amorphous polyamide is formed from a) to f) such that d) includes at least bis(4-amino-3,5-dimethylcyclohexyl)methane (TMDC).
