Study of Applying Aramid Fiber Treated Insurface to EPDM Rubber Composite Materials

Abstract:

The surface of aramid fiber is very smooth and chemical inert.The adhesiveness of aramid fiber with EPDM rubber materials is not good.So the tensile strength of EPDM rubber composite materials is influenced seriously.This paper modified the surface of aramid fiber with silicon coupling agentKH-550. We test the chang of fibers in surface with the ESCA,and the result is that content of carbon decreased ,while content of nitrogen and oxygen element increased.The activity of surface of fiber has been increased. Strength of composite materials increased from 2.58MPa to 3.22 MPa . The SEM photos of samples indicate that the weight of EPDM rubber on surface of EPDM rubber is more than untreated fiber composite materials .The treating effect on aramid fiber is best when the concentration of KH-550 is 5%,5hours.
