Study on friction and wear behavior of polyphenylene sulfide composites reinforced by short carbon fibers and sub-micro TiO2 particles

Abstract

Study on friction and wear behavior of polyphenylene sulfide composites reinforced by short carbon fibers and sub-micro TiO particles. Composites Science and Technology, Elsevier, 2009, 68 (3-4) AbstractPolyphenylene sulfide (PPS) composites filled with short carbon fibers (SCFs) (up to 15 vol.%) and sub-micro-scale TiO 2 particles (up to 7 vol.%) were prepared by extrusion and subsequently injection-molding. Based on the results of sliding wear tests, the tribological behavior of these materials was investigated using an artificial neural network (ANN) approach. A synergistic effect of the incorporated short carbon fibers and sub-micro TiO 2 particles is reported. The lowest specific wear rate was obtained for the composition of PPS with 15 vol.% SCF and 5 vol.% TiO 2 . A more optimal composition of PPS with 15 vol.% SCF and 6 vol.% TiO 2 was estimated according to ANN prediction. The scanning electron microscopy (SEM) observation revealed that this hybrid reinforcement could be interpreted in terms of a positive rolling effect of the particles between the two sliding surfaces, which protected the short carbon fibers from being pulled out of the PPS matrix.

Artificial Neural Networks: Applications in Nanotechnology

“…The feasible optimal operating conditions can be determined to fabricate monodispered uniform TiO 2 particles for practical cases. Preparation of composites of polyphenylene sulfide (PPS) filled with short carbon fibers (SCFs) and sub-micron particles of TiO 2 to study the tribological behaviour of the composite using ANNs has been reported by Jiang et al (Jiang et al, 2008). The extrusion and injectionmolding technique to prepare the particles followed by sliding wear tests to optimize the composition of PPS, suggested 15 vol.% SCF and 5 vol.% TiO 2 as the lowest specific wear rate.…”

Polymer matrices for carbon fiber-reinforced polymer composites

“…PPS's extreme inertness toward organic solvents, and inorganic salts and bases accounts for its outstanding performance as a corrosion-resistant coating suitable for contact with foods [65].…”

Carbon fiber reinforced thermoplastic composites from acrylic polymer matrices: Interfacial adhesion and physical properties

“…Because, the room temperature is higher than the T g of the polypropylene (around 0°C). Moreover, aromatic thermoplastic polymers, such as polycarbonate [16,17], polybutylene terephthalate [18], polyethersulfone [19][20][21], polyetherimide [19,22,23], polyimide [24,25], polyetheretherketone [19,[26][27][28][29] and polyphenylenesulfide [30][31][32] have also been studied for high performance carbon fibers (CFs)/polymer matrix composites. In general, the aromatic polymers have high temperature resistance, high modulus of elasticity, and water resistance.…”

“…However, the interfacial structure and the improved adhesion between the matrix polymers and carbon fibers should be important to realize the high potential of the composites. Polybutylene terephthalate [18], polyetheretherketone [19,[26][27][28][29][30] and polyphenylenesulfide [31][32][33] are semi-crystalline thermoplastic polymer matrices. The crystal size, the crystal structure, and the crystallinity would be influenced by the surface of carbon fibers as crystalization-nucleus, as well as by the cooling rate and the annealing in the fabrication process.…”
