Abstract
A textile insert consists of two layers (S.sub.1, S.sub.2) composed each of at least one partial layer (S.sub.1a, S.sup.1b, S.sub.2a, S.sub.2b). These layers are made of woven warp threads (1.sub.1a, 1.sup.1b, 1.sub.2a, 1.sub.2b) and woof threads (2.sub.1a, 2.sup.1b, 2.sub.2a, 2.sub.2b). Intermediate layers (Z.sub.1, Z.sub.2, Z.sub.3) made of standing threads (4.sub.1, 4.sub.2, 4.sub.3) that extend at least in the longitudinal direction X lie between the partial layers. The whole system is held together by straight or curved connecting threads (3.sub.1, 3.sub.2). A stable textile insert is thus obtained that allows fibrous composite materials to be produced without distortion by a pultrusion process. Sections made of such fibrous composite materials are in addition highly resistant in all three directions.
