| Abstract: |
| The effect of compatibilizer on the properties of short cotton fibers （SCF）/EPDM composites was investigated， and the compatibilizers included modified phenolic resin （RM-1），EPDM-g-MAH and organic composite based on melamine prepolymer（RC）.By adding compatibilizer，the modulus at 100% elongation of the composite generally increased，and the tensile strength，elongation at break and tear strength increased at first and then decreased.It was found that EPDM-g-MAH showed the best compatibilization effect.With 6 phr of EPDM-g-MAH，as the addition level of SCF increased，the Shore A hardness and tensile set at break of the composite increased gradually，the modulus increased，the tensile strength decreased slightly，the tear strength increased at first and then decreased，and the thermal aging property changed a little. |
