摘要
研究了玻纤增强尼龙１０１０（ＧＲＰＡ１０１０）和尼龙１０１０（ＰＡ１０１０）的力学性能受γ辐照工艺的影响。结果表明，ＧＲＰＡ１０１０和ＰＡ１０１０的拉伸强度σｓ受辐照剂量Ｒ的影响很小；在Ｒ＜０．５ＭＧｙ时，ＧＲＰＡ１０１０和ＰＡ１０１０的冲击强度σｉ和断裂伸长率εｓ皆随Ｒ的增加而降低；Ｒ＞０．５ＭＧｙ后，它们的εｓ继续随Ｒ的增加而下降，而ＧＲＰＡ１０１０的σｉ则不受Ｒ的影响。ＧＲＰＡ１０１０的辐射稳定性优于ＰＡ１０１０。
The influence of the radiation processing on the mechanical properties of the GRPA1010 (glassfiber reinforced nylon 1010) and PA1010 (polyamide 1010) was studied. The tensile strength σs of GRPA1010 and PA1010 is not affacted by γ-radiation up to 2. 0 MGy. The impact strength σi of GRPA1010 is not affacted by radiation too,as R>500 kGy. GRPA1010 has higher radiation stability than PA1010 has.The influence of oxygen was observed.
