The Preparation and Property Study of Glass Fiber and Flyash Reinforced Nylon Composites

The glass fiber and flyash reinforced nylon composites were prepared by anionic polymerization of caprolactam. The effect of surface coupling treatment of the glass fiber, activate coupling treatment of fly-ash, the adding time and proportion on the mechanical and friction properties of composites were investigated. The results showed that the glass fiber and flyash disposed by coupling agents should be added into caprolac-tam monomer together while the catalyst added, and could get glass fiber and flyash reinforced nylon compos-ites with good property. With the glass fiber reinforce nylon cooperating with flyash, they both performed good enhancement. When the glass fiber was 30 wt% and flyash was 10 wt%, nylon composites had good mechan-ical properties.
