| 摘 要： | 用扫描电镜对气辅注射成型玻璃纤维(GF)增强聚丙烯(PP)制品横截面进行观察.结果表明,在靠近气道内壁一定厚度的区域内都有发泡结构生成,而纯PP的气辅注射成型制品则没有这种发泡结构,并且这种发泡程度一般随着GF含量和气体压力的增加而增大;在形貌分析的基础上,探讨了气辅注射成型过程中GF和气体穿透对发泡结构形成的影响.

| Abstract: | Cross-sections of glass fiber(GF) reinforced PP molded by gas-assisted injection were investigated by scanning electron microscope(SEM).The results show that foaming structure is formed in the region near the gas channel surface.However,foaming structure is not found in the pure PP parts.Additionally,degree of foaming is elevated when content of GF and gas pressure increase.On the basis of the morphological analysis,the effect of GF and gas penetration on foaming structure formation during gas-assisted inje... |
