摘　　要：玻璃纤维增强聚氨酯反应注射成型的一个前提条件就是要保证组分是在低粘度下反应成型,研究了玻璃纤维添加量对每一组分粘度的影响,并对比了玻璃纤维处理先后对粘度的影响,得出的结论作为聚氨酯增强反应注射成型的指导。A pre-condition for glass fiber reinforced reaction injection moulding of polyurethane is to ensure the constituents reacted and molded under the condition of low viscosity, based on which this ppaper has studied the impacts on viscosity of each constituent caused by the glass fiber addition, compared the impacts on viscosity before and after giving the treatment for glass fiber, and given the final conclusion as the directives of RRIM-PU molding.
