Influences of Mo Fibers on Mechanical Properties of Resin Mineral Composites

Abstract

The influences of new, scrap, and five modified Mo fibers on interface bonding strength of fiber-matrix and mechanical strength of RMC were studied. Typical specimens with different fibers and mass ratio of resin and hardener were prepared to verify the above assumptions. Theoretical analysis and experimental results prove that, compared with ordinary new Mo fibers, scrap Mo fibers can perform better in improving interface bonding strength and mechanical properties of RMC because many discharge pits randomly distribute on the surface of scrap fibers. For five modified Mo fibers, interface bonding strength and the reinforcing effect on RMC have been improved obviously. Wherein, comprehensive mechanical properties of RMC are optimal with the addition of M6 fibers which have undergone combined surface treatment including acidification, gasphase oxidation and coupling treatment. And interface bonding strength between M6 fiber and matrix is the maximum.
