Embodiment 1
[0057] Through the above-mentioned first production method (such as figure 1 , 2 shown) to produce 106 shaped cloth, that is, glass raw materials are drawn to form glass filaments, and at least two glass filaments are paralleled to form glass filaments, and then resin composed of epoxy resin, curing agent and toughening agent is used The composition solution is used to impregnate the glass strands. After the impregnation, it is dried and semi-cured, and then twisted, warped, and weaved according to the specifications of 106 sizing cloths. After the weaving, it is dried in an oven at 170°C. After curing for 90 minutes, a 106 shaped cloth is obtained, and the resin weight content in the 106 shaped cloth does not exceed 30%. Subsequently, the 106 shaped cloth is dipped in a resin composition solution composed of epoxy resin, curing agent and toughening agent, etc. for impregnation treatment, and the 106 shaped cloth after the dipping treatment is baked in an oven at 155° C. for ...
Embodiment 2
[0059] Through the second production method above (such as figure 1 , 3 shown) to produce 106 shaped cloths. Specifically, glass raw materials are drawn to form glass filaments, at least two glass filaments are paralleled to form glass filaments, and the glass filaments are sequentially twisted and warped to form Warp the warp yarn, and then use a resin composition solution composed of epoxy resin, curing agent and toughening agent to impregnate the warp yarn, dry and semi-cure the warp yarn after the dipping treatment, and then carry out according to the specifications of 106 sizing cloth Weaving treatment, after the weaving treatment, bake in an oven at 170°C for 90 minutes and solidify to obtain 106 shaped cloth, the weight content of resin in the 106 shaped cloth is not more than 30%. Subsequently, the 106 shaped cloth is dipped in a resin composition solution composed of epoxy resin, curing agent and toughening agent, etc. for impregnation treatment, and the 106 shaped c...
