摘要:

分别采用超声波法和物理机械法对芳纶纤维进行表面改性,研究了两种处理方法对其表面形貌、

分散性以及EPDM 复合材料性能的影响。结果表明:超声法和机械法使芳纶纤维表面形成差别较大的形貌特

征;其中芳纶经机械处理后呈现良好的分散性,其复合材料的拉伸强度和烧蚀深度分别为11. 3 MPa 和1. 2 mm

(10 phr),优于超声波法处理的结果。

Abstract:

Kevlar fibers were modified by mechanical method and ultrasonic treated with different time, respec鄄

tively. The effects of the two methods on the surface morphology of fibers, the dispersion of fibers within EPDM, and

the mechanical and anti鄄ablative properties of EPDM composites were investigated. Results showed that the roughness

was remarkably increased for the fibers treated by the two methods basing on different mechanism. The mechanical

and anti鄄ablative properties of EPDM composites (11. 3 MPa and 1. 2 mm, respectively) are superior to that of EPDM

composites filled with ultrasonic鄄treated Kevlar fibers, which is because of the homogeneous dispersion of fibers within

EPDM phase.
