Uni-directional fibre preform having slivers and consisting of reinforcing fibre bundles, and a composite material component

由增强纤维束制成且含单向纤维带的纤维预制件以及复合件

Abstract

本发明涉及一种用于制造纤维复合结构的纤维预制件(1),所述预制件的壁包含至少一个由具有第一树脂组合物的增强纤维束(5)所组成的第一区(4)和至少一个由至少一条纤维带(其由至少一条具有第二树脂组合物的单向导向增强纱股(8)组成)所组成的第二区(7),其中在按平行厚度延伸的方向观看时,在所述至少一个第一区(4)中的增强纤维束(5)以彼此不同的空间方向排列,且其中在按垂直壁厚延伸的方向观看时,所述至少一个第二区形成不连续区域。此外,本发明涉及由此类纤维预制件组成的复合材料件。
The invention relates to a fibre preform (1) for producing fibre composite structures, the wall of said preform comprising at least one first zone (4) that consists of reinforcing fibre bundles (5) with a first resin composition, and at least one second zone (7) consisting of at least one sliver, consisting of at least one uni-directionally aligned reinforcing yarn strand (8) with a second resin composition, said reinforcing fibre bundles (5) being oriented, in the at least one first zone (4) and in an observation direction, parallel to the thickness extension in different spatial directions from one another, and the at least one second zone forming, in an observation direction, a discrete region that is perpendicular to the thickness extension of the wall. In addition, the invention relates to a composite material component that consists of such a fibre preform.
