  Abstract

With superior vibration alleviation property, mineral-filled polymer composite (MFPC) has attracted more attention in the field of mechanical manufacturing. However, the application of MFPC is limited by its inferior mechanical strength. Straight-line and special-shaped Mo fibers were respectively added into MFPC to improve its mechanical properties in the paper. The influences of fiber shape and matrix performance on interface bonding property of fiber-matrix were studied systematically. And the effects of fiber shape and fiber content on compressive and flexural strength of MFPC were separately discussed. Finite element analysis was employed to further verify experimental results. Compared with straightline fiber, both pulling ability and interfacial bonding strength of special-shaped Mo fiber are greatly improved when mass ratio r of resin and curing agent is identical. For the same fiber, interface bonding strength of r=4:1 is obviously greater than that of r=7:1. The maximum mechanical strength is achieved when mass fraction of fibers is 1.2 %. Mechanical properties of MFPC reinforced by special-shaped fibers are much better than those reinforced by straight-line fibers. By contrast, the reinforcing effect of M-shaped fibers is optimal, followed by N-shaped, U-shaped the third, and V-shaped the minimum, which consists with the results of finite element simulation.
