Woven textile material based on glass fibres for reinforcing moulded components has given ratio between thickness and numbers of weft and warp filaments

摘要

The woven textile material (1), based on high-strength fibres, especially of glass, is made from warp (2) and weft (3) filaments that are not perpendicular to one another. The filaments have a ratio of Tc.Dc/Tt.Dt that is between 0.2 and 1 : 1, where Tc is the thickness of the warp filaments, Tt is the thickness of the weft filaments, Dc is the number of warp filaments per unit of length, and Dt is the number of weft filaments per unit of length. The material can have a serge weave, with an angle of 30 - 80 degrees, and preferably 60 degrees, between weft and warp filaments, and two or more layers can be used to reinforce a moulded component, the layers being joined together by an adhesive that is compatible with the moulding process.
