Abrasion wear behavior of glass–basalt hybrid thermoplastic composites under the influence of abrading load and velocity: Multipass effect Available to Purchase

The impact of abrasion particles on two body abrasion wear characteristics of Glass-Basalt hybrid thermoplastic composites is studied under the action of varying velocity and load. The blend(PA66/PTFE)(80/20 wt.%), Blend/10 wt.% short glass fiber (SGF), Blend/ 10 wt.% short basalt fiber (SBF) and Blend/ 10 wt.% SGF and 10wt.% SBF (GB) were the material systems used to study the abrasion effect. The experimentation have been carried out for different loads (2.5. 5, 7.5 and 10 N) and varying velocities (0.25, 0.5, 0.75 and 1 m/s). It is responded from the experiment that the abrasion wear resistance of SGF filled composites is superior than SBF filled ones. This may due to poor load carrying capacity of SBF composites. The superior abrasion wear resistance of Glass-Basalt hybrid composites than mono fiber filled composites is due to increase in fracture energy of hybrid composites as an effect of hybridization. It is observed from the experimentation that the abrasion wear is critical at lower load and velocity where as it becomes adhesive wear at higher load. Increase in sliding velocity increases the thermal adhesion and debonding of fibers. It is evident from the SEM studies that fiber debonding, microploughing and matrix deformation are some of the failure mechanisms.
