摘要

Particulate-filled polymer composites (PFPC) have received a great deal of attention in the field of precision machine tools because of their excellent vibration-alleviating property. However, applications of PFPC in the field of precision machine tools are restricted by its limited mechanical strength. The pores in PFPC are one of the key influences on its mechanical properties, such that the porosity determines the overall mechanical properties of the PFPC directly. In this paper, the relationship between porosity and mechanical properties (compressive strength, flexural strength, elasticity modulus) and damping ratio of PFPC was studied systematically. A strong correlation between the porosity and the mechanical properties and damping ratio of PFPC was found. The results show that the mechanical properties (damping ratio) of PFPC deteriorated (increased) dramatically with increasing porosity. An empirical formula was proposed for the relation between the porosity and the mechanical properties (and damping ratio) of PFPC. (c) 2016 Wiley Periodicals, Inc. J. Appl. Polym.
