Abstract:
A method for manufacturing a composite material, the method comprising: positioning a first fabric layer between a first Kraft paper layer and a second Kraft paper layer; impregnating the first fabric layer with a binding composition while maintaining the first Kraft paper layer and the second Kraft paper layer dry; assembling the impregnated first fabric layer, the first Kraft paper layer and the second Kraft paper layer together to form a first pre-impregnated multilayer assembly; applying pressure on the first pre-impregnated multilayer assembly to diffuse the binding composition from the first fabric layer to the first Kraft paper layer and the second Kraft paper layer; and curing the first pre-impregnated multilayer assembly.
