摘要:
A fiber reinforced resin composite for ballistic protection comprising a plurality of first and second plies wherein the first and second plies further comprise a woven fabric and a polymeric resin. The fabric has a Russell tightness factor of from 0.2 to 0.7 and a cover factor of at least 0.45, The fabric is impregnated with the resin, the resin comprising from 5 to 30 weight percent of the total weight of fabric plus resin. The fabric of each first and second ply comprises regions wherein the fabric is distorted from an orthogonal woven state by a distortion angle of least 30 degrees. The composite may further comprising a third ply having a surface area no greater than 50% of the surface area of a first and second ply. The ratio of the number of first plus second plies to the number of third plies is from 2:1 to 12:1.
