Study on the tensile fracture characteristics of cars oil filter materials

摘要

The oil filter materials are frequently subjected to abrading and all kinds of friction and making the materials suffered from damage, consequently, the property and service life of the filter materials is reduced. So the purpose of this thesis is to research the tensile performance of the automobile oil filter material and according to constant speed tensile test to measure the macro fracture characteristics, tensile property in the process of before and after tensile testing, tensile fracture form and the math expression. Then compared the breaking strength, breaking elongation, elongation at break and breaking work of these ten oil filter materials. Hope that through the study on the tensile performance of the oil filter materials and summarizes the damage mechanism and tensile fracture form, in order to provides a new way to develop the new material.
