Abstract: |
HNBR/short aramid fiber(DCAF)/fibrillar silicate(FS) composites were prepared by mechanical blending of in situ modified FS,DCAF and HNBR.The effects of the addition levels of DCAF and FS,and different lengths of DCAF on the structure and properties of the composites were investigated.The results showed that the moduli of the composites under both tension and compression conditions at small strain were increased by adding DCAF;the tensile properties and anisotropy of the composites could be improved when the length or addition levels of DCAF increased;the stress strain behavior and compression modulus of the composites were improved significantly by adding FS. |
