A sandwich composite material (300) formed of a core layer (310) positioned between first and second skin layers (320, 330) is provided. Either the core layer or the first and second skin layers are formed of a composite material that includes reinforcement fibers and organic fibers. Preferably, the reinforcing fibers are wet use chopped strand glass fibers. The composite material may be formed by opening the reinforcement fibers, blending the reinforcement and organic fibers, forming the reinforcement and organic fibers into a sheet, and bonding the sheet. The core layer and first and second skin layers may be attached by adhesives or resin tie layers. The sandwich composite material may include a facing layer affixed to an exposed major surface of one or both of the first and second skin layers. The strength, stiffness, and load deflection of the sandwich composite material may be modified by changing the amount and/or type of fibers present.

L'invention concerne un matériau composite sandwich (300) à couche centrale (310) entre des première et seconde couches superficielles (320, 330). L'une au moins de ces trois couches est en matériau composite à fibres de renforcement et fibres organiques. De préférence, les fibres de renforcement sont des fibres de verre à fibres coupées par voie humide. Le matériau composite peut être constitué par ouverture des fibres de renforcement, mélange de ces fibres avec des fibres organiques, mise en feuille, et liaison de la feuille. Les trois couches susmentionnées peuvent être fixées par le biais d'un adhésif ou de couches de liaison en résine. Le matériau peut comprendre une couche faciale fixée sur une surface majeure exposée de l'une ou des deux couches superficielles. La solidité, la rigidité et la déformation en charge du matériau peuvent être modifiées par une modification de la quantité et/ou du type de fibres utilisées.
