- 14 - Abstract A composite lining material is a thermoplastics sheet (e.g. polypropylene) bonded to one face of a non- wogen web of fibres (e.g. polyester) through which continuous filaments (e.g. polyester) are stitched, e.g. in chain or tricot stitch. A reinforcing layer, e.g. of fibre-reinforced resin, is applied to the other face of the web to provide a lined wall structure which may be the wall of a lined pipe, vessel or tank. The continuous filaments are bonded to the lining and reinforcement layers at multiple, spaced locations and provide a direct, mechanical link between those layers in addition to reinforcing the fibrous web. Shear strengths of greater than 100 kg/cm2 and steady peel strengths of greater than 7.0 kg/cm are obtainable, and there is good retention of these properties at elevated temperatures.
