<p>A composite lining material has a thermoplastics sheet (2) (e.g. of polypropylene) bonded to one face of a non-woven web (4) of fibres (e.g. polyester) through which continuous filaments (5) (e.g. of polyester) are stitched, for example in chain or tricot stitch. A reinforcing layer (3), for example of fibre-reinforced resin, is applied to the other face (8) of the web (4) to provide a lined wall structure which may be the wall of a lined pipe, vessel or tank. The continuous filaments (5) are bonded to the lining and reinforcement layers (2, 3) at multiple, spaced locations (9) and provide a direct, mechanical link between those layers in addition to reinforcing the fibrous web (4). Shear strengths of greater than 100 kg/cm<2> and steady peel strengths of greater than 7.0 kg/cm properties at elevated temperatures. <IMAGE></p> |
