美国联合公司的纤维部最近发表了一种用于注射成型的增强纤维,该纤维称为Compet聚酯纤维。它能提高注射模塑的一些特性。经试验测定表明,在玻璃纤维增强复合材料中掺加少量的Compet纤维,能够明显地改进复合材料的耐冲击强度,而不影响玻璃纤维增强复合材料的拉伸或弯曲强度。这种Compet聚酯纤维不同于玻璃纤维和其它增强纤维,它在注射模塑期间不易折断,这就给加工者提供理
The fiber department at United United recently published a reinforcing fiber for injection molding called the “Compet” polyester fiber. It can improve some of the features of injection molding. The experimental results show that adding a small amount of Compet fiber to glass fiber reinforced composites can obviously improve the impact strength of the composites without affecting the tensile or flexural strength of the glass fiber reinforced composites. This type of Compet polyester differs from fiberglass and other reinforcing fibers in that it does not break easily during injection molding,
