10 Multiaxial fabrics What are multiaxial fabrics? Multiaxial fabric consists of one or more layers of differently aligned held in place by a stitching yarn 10

11 Multiaxial fabrics Why multiaxial fabrics? Woven fabric Yarns bend over each other (= web crimp) Indirect utilization of fiber strength Only 0 /90 directions possible Multiaxial fabric Yarns remain straight, no crimp Direct linear utilization of fibre strength Different angles/ more then two angles in one fabric possible 11
