Glass fiber winding equipment defect analysis, control measures and repair 1, composite material surface hair sticky, its main reason is as follows. A) air humidity. Because water vapor to unsaturated polyester resin, epoxy resin has the effect of delay, even can cause surface permanent hair sticky, product is not complete and so on. Therefore, in order to ensure that in the case of relative humidity is lower than 80%. Too much too much film) the product surface and air isolation. C) curing agent and accelerant amount does not meet the requirements, so in the configuration of glue should be strictly in accordance with the Technical Documentation specified formula to control the dosage. D) for unsaturated polyester resin, styrene volatility caused by the resin of styrene monomer. The requirement of resin solidification can not be heated, on the other hand, ambient temperature should not be too high (usually 30 degrees is appropriate, and the ventilation volume shoulds not be too big. 2, the products bubble. The reasons are as follows. A) drive pressure bubble is not thorough, each layer of laying, winding to roll for repeated rolling, the roller should be made ring to zigzag or longitudinal B resin viscosity is too large, in the mixing or brushing, into the resin in the air bubble can not be driven out. Need to add the right amount of diluent. Unsaturated polyester resin for styrene; epoxy resin diluent can choose ethanol, acetone, toluene, xylene and other non active or glycerol ether type. C) to enhance the material selection, should be re considered the use of reinforced material type, the choice of appropriate dip coating, brushing, rolling angle and so on. Stratification caused by excessive or inappropriate without stratification, the reasons are as follows. A) fiber fabric pretreatment or treatment is not enough. B) fabric in the process of winding tension is not enough, or bubble too much. C) resin dosage is not enough or the viscosity is too high, the fiber is not soaked. D) formula is not reasonable, leads to bonding performance is poor, or curing speed is too fast, too slow. E) after curing, process conditions (generally is premature heat curing temperature). Whatever the reason, must eradicate layered portion, and with the angle grinder and polishing machine polishing off the defective area outside the perimeter of the resin layer, the width of not less than 5 cm, and then To carry out the shop floor according to the requirements of the process, for all kinds of defects, regardless of the reasons, should take appropriate measures to completely eliminate, in order to meet the quality requirements.
