    摘要: Provided is a fabric to which an uneven-surface design which is fine and has flexibility and wear resistance is imparted. The fabric has a polyurethane resin applied portion on at least a portion of a surface side of the fabric, and an uneven-surface design shaped on the polyurethane resin applied portion. The polyurethane resin applied portion is a region in which a polyurethane resin which is applied is present, and the polyurethane resin permeates between the fibers at least in a surface portion of the fabric such that a surface of the fabric is formed by the polyurethane resin and the fibers. In the polyurethane resin applied portion, an application depth of the polyurethane resin is 50 to 200 µm, a filling ratio of the polyurethane resin is 15% to 45%, and a filling ratio of the fibers of the fabric is 50% to 80%.

    摘要: The invention relates to an aqueous impregnation bath for reinforcement fibres for manufacturing prepregs having a thermoplastic matrix, resulting in highly satisfactory stabilisation, in terms of residual porosity, of the composite material parts manufactured using said prepregs. Said impregnation bath includes a least one thermoplastic polymer, a surfactant and water, and is characterised in that the surfactant is a stearyl alcohol ethoxylate of formula: HO-(CH
    2 -CH
    2 -O)
    n -CH
    2 -(CH
    2 )
    16 -CH
    3 wherein n is 100. The invention also relates to a method for impregnating reinforcement fibres using said impregnation bath, to a method for manufacturing a prepreg having a thermoplastic matrix using said impregnation method, and to a method for manufacturing a part made of a composite material having a thermoplastic matrix using the method for manufacturing a prepreg. The invention is useful in any field for manufacturing parts made of composite materials and, specifically, in the aeronautical, space, rail, shipping and automotive industries.
