The mechanical properties of the composite material forbearing pad, which is made of the aforementioned plastics as matrix reinforced by fine bronzeelastic springs, are modeled and relaxation modulus of the material are presented. The differencebetween these two kinds of PTFE is studied. The results show that the complex modulus of PTFEplastics for bearing pad is higher than that of normal PTFE plastics.展开更多

文摘The viscoelastic properties of the normal PTFE plastic and strengthened PTFEplastic for bearing pad are measured. The mechanical properties of the composite material forbearing pad, which is made of the aforementioned plastics as matrix reinforced by fine bronzeelastic springs, are modeled and relaxation modulus of the material are presented. The differencebetween these two kinds of PTFE is studied. The results show that the complex modulus of PTFEplastics for bearing pad is higher than that of normal PTFE plastics.
