FIBROUS STRUCTURE FOR PREPARING COMPOSITE MATERIALS AND PROCESS FOR PREPARING THEREOF

摘要

The composite fibre reinforcement material, with a spring effect, is a layer of thicker fibres from a carding stage. Immediately after carding, continuous glass filaments are directed at the web surface, to lie on it in all directions. The web and filaments are mechanically bonded by needling, which draws the glass filaments through the web thickness. The web is of synthetic fibres to spring against the opposite face. The resultant material is coiled.
