| Abstract: |
| The microstructure and tensile failure mechanism of nylon short fibre/NR foam composite were investigated.The results showed that the untreated short fibre in the short fibre/NR foam composite tended to be the nucleus of micro-pores and many fibres hung in the pores；the stress concentration tended to occur at the place around untreated fibres resulting in the origination of flaw and the drawnout of short fibre during tensile failure；and the pretreated short fibre was bonded well to rubber matrix and could bear the applied stress to prevent the composite from the crack propagation during tensile. |
