Title:
COMPOSITE MATERIAL ROLLER
Document Type and Number:
WIPO Patent Application WO/2011/018903
Kind Code:
A1
Abstract:
Disclosed is a composite material roller that itself rotates, the composite material roller comprising a cylindrical multilayer structure (1) composed of a plurality of pieces of fiber-knitted fabric (2) impregnated with a resin and a sheet (4) which is constituted of fibers different from the fibers of the multilayer structure (1) and which covers the circumferential surface of the multilayer structure (1). The fibers of the fabric (2) have a modulus of longitudinal elasticity lower than the modulus of longitudinal elasticity of the resin of the fabric (2). The fibers of the fabric (2) have a hardness lower than the hardness of the resin of the fabric (2). Thus, the composite material roller can come into contact with a structure at a reduced areal pressure imposed thereon.
