Effects of particle size, particle loading and sliding distance on the friction and wear properties of cenosphere particulate filled vinylester composites

Dry sliding wear of epoxy/cenosphere syntactic foams

“…Figure 8(a) shows that the wear rate increases with the applied load. Further, it is observed from Figure 8 The wear rate of polymer composites is influenced by the formation of a transfer film on the counter face when a polymer slides against the material, leading to reduced w t [8,13,18]. The wear rate is plotted as a function of cenosphere content at different normal loads in Figure 8(d).…”

“…Increasing use of syntactic foams in automotive and aerospace applications requires understanding their tribological properties. Although detailed studies on wear behavior of metal matrix syntactic foams are available [3][4][5][6], similar studies on polymer matrix syntactic foams are relatively scarce [7][8][9]. In addition, due to a large number of parameter involved in wear testing, a clear understanding of structure-property correlations requires considerable additional effort.…”

“…Table 1 summarizes the studies found in the literature where cenosphere filled polymer matrix composites are studied for tribological properties > @. Wear behavior of cenosphere filled vinyl ester and polyester matrix syntactic foams has been reported [7][8][9]. Chauhan et al [8] studied the friction and wear characteristics of vinyl ester/cenosphere syntactic foams under dry sliding conditions for different cenosphere sizes, applied loads and sliding speeds.…”

“…Wear behavior of cenosphere filled vinyl ester and polyester matrix syntactic foams has been reported [7][8][9]. Chauhan et al [8] studied the friction and wear characteristics of vinyl ester/cenosphere syntactic foams under dry sliding conditions for different cenosphere sizes, applied loads and sliding speeds. It was found that the submicron and micro-sized cenospheres are capable of improving mechanical properties and wear resistance of syntactic foams.…”

Tribological response of an epoxy matrix filled with graphite and/or carbon nanotubes

“…It has been found that particle size has great influence on the tribological performance of polymer composites [21]. When the particle size is reduced down to the nanoscale, the friction and wear behavior of filled polymers is greatly affected at very low nanoparticle content as compared to the effect of low micro-filler content on friction and wear behavior of the filled polymers [22]. But the influence on friction and wear behavior of nanoparticles in polymer matrices depends on many factors such as the type of polymer, type of nanoparticle, filler content, size, shape, and operating conditions [6].…”
