Abstract
Disclosed is a flexible material including a web of fibers chosen in the group consisting of carbon fibers, glass fibers and aramid fibers, this web of fibers being impregnated on a so-called external face with an impregnation layer produced from a polymer binder and containing at least one plasticizing agent or a mixture of plasticizing agents. A fibrous textile substrate is superimposed on the web of fibers on an internal face of the web opposite the external face.
Claims18
A flexible material comprising:
- a web of fibers chosen from the group consisting of carbon fibers, aramid fibers, and any combination thereof,
- wherein said web of fibers is impregnated on a first face, called the external face, with between 250 and 400 g/m2 of a polymer binder to form a first impregnation layer wherein the impregnation layer comprises at least one adipic acid ester, and wherein the polymer binder consists of a copolymer of vinyl pyrrolidone and of vinyl acetate, and
- a fibrous textile substrate superimposed on a second face of said web of fibers, called the internal face, opposite said external face.
