Abstract
Microfibrillar reinforced composites (MFCs) were prepared from polyethylene terephthalate (PET) and high density polyethylene (HDPE). The mechanical and tribological properties of the MFCs were investigated. Static and dynamic mechanical tests revealed that the tensile strength, tensile modulus, and dynamic modulus of the HDPE matrix were improved greatly. Wear mechanism analysis demonstrated that the ability of HDPE to form transfer films on the counter rings was strengthened, which was responsible for the variation of friction and wear properties of the matrix.
