SHEET MATERIAL, PROCESS FOR ITS PRODUCTION AND A COMPOSITE STRUCTURE

摘要

A sheet material useful for preparing high strength composite structures, especially in the field of light weight construction material, comprises a layer (A) of a high strength fibrous material impregnated and/or coated with a curable synthetic resin in the B-stage and a layer (B) of a polyamide polymer or another polymer having similar properties and being compatible with the curable synthetic resin of layer (A), which layer (B) is partially or completely bound to or embedded in layer (A).
