Embodiment Construction
[0024] Use liquid phenolic resin (or modified phenolic resin) as the adhesive. Friction modifiers may or may not be used. Reinforcement materials are: glass fiber, aramid fiber, copper wire and friction spinning. Friction spinning is made by blending viscose fiber, glass fiber and acrylic fiber in a ratio of 1:1:1. Its formula is as follows:
[0025]
[0026] The manufacturing method is as follows:
[0027] The glass fiber, the aramid fiber, the 0.2mm copper wire and the friction spinning yarn are plied according to the above ratio, and the plied twist is 9-10 / 10CM.
[0028] Then the twisted on-line knitting machine is woven into a grid cloth with a width of 900 mm, a warp density of 38 / CM, and a weft density of 30 / CM.
[0029] Put the grid cloth into a dipping tank filled with liquid phenolic resin to fully impregnate it, remove it and drip it dry, bake it in an oven at 100°C for 1 hour, and then take it out.
[0030] Then cut according to the size of the desired fric...
