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 permeability,and the quick speed of resin soaking.etc.The surfacing tissue is applied in the FRP,its good air permeability can make the resin to be permeated quickly,throughout eliminate the appearances of the bubbles and the white stains,its good die-fitting capabilty 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-permeability 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,it is really the necessaries in the manufacturing of the high quality FRP dies and its products.
