Abstract
This research is devoted to study the effect of different in weight percentage of Sio2 particles and glass fibers (5, 10, 15, 20) wt. % on the wear rate epoxy resin. The results show that the value of hardness increase with the increase for the weight percentage of reinforcing particles and fibers, while the wear rate decrease with the increase the load level of the reinforcing particles and fibers . The largest value of the hardness, and the lowest value of the wear rate for epoxy reinforced with 20% of SiO2, the wear rate increase in general with increasing the applied load.
Highlights
Polymer based materials are finding increasing use in many applications owing to their strength,lightness, ease of processing and availability of wider choice of systems [1]
Suresha [10] investigated the Friction and Dry Slide Wear of Short Glass Fiber(SGF) Reinforced Thermoplastic Polyurethane(TPU) Composites, The results reveal that the slide wear loss increases with increasing load/sliding velocity
The fibers will randomly distribute inside the sample and there are rich resin will form between fibers, so that the hardness for their samples will decrease and the fraction will increase
Summary
Polymer based materials are finding increasing use in many applications owing to their strength,lightness, ease of processing and availability of wider choice of systems [1]. The matrix is the component that holds the filler together to form the bulk of the material It usually consists of various epoxy type polymers but other materials may be used. Suresha et al [7] investigated the friction and wear behavior of glassepoxy composite with and without graphite They fabricated neat glassepoxy composite and graphite filled glass-epoxy composite with three different percentages of filler. The wear resistance increases with increasing the sliding velocity, with decreasing the applied contact pressure and with selecting the most favourable glass fiber volume fraction. B. Suresha [10] investigated the Friction and Dry Slide Wear of Short Glass Fiber(SGF) Reinforced Thermoplastic Polyurethane(TPU) Composites , The results reveal that the slide wear loss increases with increasing load/sliding velocity. 40% SGF reinforced TPU composite exhibited lower friction coefficient and wear rate than 20 and 30% SGF reinforced TPU composites
