    Abstract: The fibre-reinforced malleable semi-product, containing a thermoplastic polymer and giving a needle bonded fabric, is composed of at least two layers of which one is drawn and oriented continuous filaments with a max. material weight of 300 g/m2. At least one layer is of unoriented fibres. The weight ratio of the layers A:B is from 80:20 to 40:60. The building-up of the layers is pref. in the sequence ABAB, ABABAB or ABABABAB. The resulting semi-product has layer A on its outer surface.

    Abstract: A fibre-reinforced, thermoplastic, mouldable semi-finished prod contains a thermoplastic polymer and a symmetrically needled glass fibre mat. The glass mats are pref needled so that the number and length of fibres projecting on both surfaces are about equal, and the length of the projecting fibres is less than 2 mm. The glass mat has a tensile strength of 10-50 N, measured on a strip 100 mm wide, and a flat wt of 200-2500 g/square m.
