The processing technology peculiar to the glass fiber surfacing tissue determines it possessing the characteristics of the leveled surface, the even fiber distribution, the soft feel, the good air pemeability, and the quick speed of resin soaking,etc. The surfacing tissue is applied in the FRP,its good air pemeability can make the resin to be pemeated quickly, throughout eliminate the appearances of the bubbles and the white stains, its good die-fiting capability is suitable for the surfaces of any products with conplicated shapes, which can cover the cloth veins, increase the degree of finish and the anti-pemeability of its surfaces, at the same time,strength the layer's shearing strength and the surface's tenacity, so that to cause the product's corrosion and temperature resistivities to be raised to some extent.
