Multi-axial reinforcement fabrics are made up of several plies of parallel fibres, which can be laid in different orientations. The individual layers are then stitched together with a polyester thread to form a single ‘multi-axial reinforcement fabric which can be cut shaped and placed dry into a mould in the exact position needed for the finished part. Being stitched, a multi-axial fabric can be cut to shape and handled without falling apart and it has excellent in-mould drape ability for accurate dry lay-up.

Double Bias fabric is a two layer fabric with fibreglass roving laid down parallel in the – 45° and + 45° axis. Lightweight stitching holds these fibres together and parallel in each layer. Double Bias fabrics are used where complex contours and curved surfaces make other fabrics hard to laminate. This fabric adds good structural support to square composite panels and provide stability in long laminates, which may experience torsional twist. Double Bias fabrics are often cut into strips for joining hulls, decks and bulkheads.
