In a process that is particularly suitable for producing pipes or hoses, the reinforcing material and the matrix material are no longer produced separate ly but together in a woven, knitted, braided or non-woven fabric. The matrix materi al is selected so that its melting temperature is lower than the melting or decomp osition temperature of the reinforcing material. The end product is obtained by pult ruding the fabricated material, generally designated as textile fabrics, at a tempe rature above the melting temperature of the matrix material and below the melting o r decomposition temperature of the reinforcing material. The product is then c ooled to stabilise its final shape.
