| Abstract: |
| The powdered coal ash fiber was modified by aluminum zirconium complex coupling agent，the powdered coal ash fiber/NR composite was prepared and its properties were investigated.The results showed that，the interfacial bonding conditions of the fiber and rubber matrix could be improved by fiber modification with aluminum zirconium complex coupling agent；the optimum addition level of the powdered coal ash fiber was 40 phr；at that addition level，the physical properties and insulating property of the composite were obviously improved，but tear strength slightly decreased. |
