Beschreibung
Zusammenfassung:	A fiber reinforced resin composite for ballistic protection comprising a plurality of plies (10,20) comprising a woven fabric and a polymer not ic resin. The fabric has a Russell tightness factor from 0.2 to 0.7 and a cover factor of at least 0.45. The fabric of the plies comprises regions wherein the fabric is distorted from an orthogonal woven state by a distortion angle of least 30 degrees. The composite may further com not prising a third ply (30) having a surface area no greater than 50% of the surface area of a first and second ply.
