Non-crimp fabricNCF

A stitched, non crimp reinforcement with two fibre layers at set orientations, most commonly plus and minus 45 degrees or 0 and 90 degrees. The layers are held together by a fine stitching yarn rather than interlaced, so the fibres stay straight and translate their properties efficiently into the laminate.

A stitched reinforcement in which two or more layers of fibres at different orientations, as in biaxial, triaxial and quadraxial constructions, are combined in a single fabric. It allows several plies to be laid in one operation, cutting layup time on large structures such as wind turbine blades and boat hulls.

A reinforcement in which nearly all fibres run in a single direction, held together by light stitching, a binder or occasional weft threads. It delivers the highest stiffness and strength along the fibre axis and is used where loads are strongly directional, for example wind blade spar caps and bonded strengthening plates.

A heavy, coarse fabric woven directly from untwisted glass rovings, usually in a plain weave. It builds laminate thickness and directional strength quickly and is traditionally alternated with chopped strand mat in marine and industrial GRP laminates.
