The results show a few grooves appear on the worn surface of the composites which contain 10 phr nano - al2o3 there are a great many grooves on the worn surface of the composites containing 20 phr. in addition the deeper cracks also appear. this shows that excess nano - al2o3 particles ca n ' t improve wear properties of pa6 ' s. the proper content of nano - al2o3 in the matrix can enable the molecular chains of pa6 to produce closed joints which resemble the physical crosslinking
尼龍6 / a12o :復合材料的加工性能研究表明:隨著納米a12o3的加入，復合材料的熔體流動速率下降，納米a12o3含量越大，下降越明顯，即隊6 / a12o3納米復合材料的加工性能越差;隨著納米a12o3的加入，復合材料的轉矩和塑化時間都增加，當含量小於巧phr時，隊6復合材料的轉矩增加幅度不大，當含量超過15phr后，轉矩急劇升高。 -
Nano - al2o3 particles which are embedded in the matrix can impart additional strength to the composite and act as bearing of stress. furthermore, these organically - treated particles can effectively link the molecular chains of pa6, and this state is similar to physical crosslinking joints. all these together contribute to the improvement of mechanical properties and hardness
硬度試驗表明，隨納米al _ 2o _ 3填充粒子量的增加，材料的硬度呈現增加趨勢，這主要是因為納米al _ 2o _ 3在尼龍6中類似於「物理交聯」 、充當剛性支撐點作用，從而使尼龍6的硬度提高。 -
