Abstract: The newly designed composite pipe combines the positive properties of plastic pipes with the significantly increased strength of a textile reinforced fine grained concrete layer. The jacket of textile reinforced concrete consists of warp knitted fabrics made of alkali-resistant glass yarns. It bears the stresses from internal pressure as well as external loads (live loads, earth loads, etc). Very positive results were achieved by adding short glass fibers with rates of less than 1 Vol.-%. The wall-thickness of the interior plastic pipe may be reduced for the same or even higher internal pressure loads. A suitable formation of the textile reinforcement allows failure pressures of up to 6 MPa (60 bar). The application of the new composite pipes is supposed to occur in the field of water supply and sewage disposal. A manufactured production facility at laboratory scale allows the production of composite pipes by a winding technique. The manufactured specimens are tested on specially developed experimental equipment for measuring the extension under internal pressure loads. A further emphasis is placed on the examination under apex pressure load.
