3) hand paste resin with low molecular weight; 2) glass fiber content can not be too high, carbon fiber, woven roving (cloth) etc.. Although the thick aramid fabric is difficult to be soaked with resin manually. (2) The raw material is unsaturated polyester resin; 2) It can be formed at room temperature. Operate the layer repeatly for several times. (3) the advantage 1) It is suitable for the production of a small amount of solvent. The mechanics and thermal properties are limited because of the high techinicals.
