玻璃纤维直径对BMC团料以及力学性能影响的研究

Influences of Glass Fiber Diameter on BMC and Its Mechanical Properties

介绍了不同直径玻璃纤维对BMC团料的影响,并系统研究了不同纤维直径对BMC弯曲强度、拉伸强度以及冲击强度等力学性能的影响。结果表明,随着纤维直径的增大,玻纤在树脂中的浸透速度变慢,在树脂糊中的粘度会增大,当玻璃纤维直径在13~15μm,对复合材料力学性能增强效果最显著。

The influence of different diameter glass fibers on bulk molding compound （BMC） are discussed in de- tails of effects of fiber diameter on mechanical properties such as flexural strength, tensile strength and impact strength. The results have shown that with the increase of fiber diameter, the wet-out rate of glass fibers in resin de- creases and their adhesion in resin paste increases. When the diameter is 13 - 15 microns, the fibers contribute most significantly to the mechanical properties of composite materials.
