摘　　要：研究了结晶树脂和氧化镁复合增稠体系低压片状模塑料的纤维分布影响因素,通过测量纤维含量的方法研究了LPMC的粘度、纤维含量、闭模速度对纤维分布的影响。根据各种粘度要求,通过改变树脂糊中氧化镁、结晶树脂及填料的含量,调整结晶树脂粉料的粒度,将模内粘度控制在可低压成型的范围内,并且满足熟化要求。In this paper, effect factors on fiber dispersion of low-pressure sheet molding compounds were investigated. Effects of LPMC viscosity, fiber content and close mold speed on fiber dispersion were also researched by measuring the fiber content. According to various viscosity demands, by changing the contents of MgO, crystal resin and filling in the resin paste, the molding viscosity could be controlled in appropriate range, which can molding under low pressure and satisfy the thickening demand.
