Abstract
ABSTRACTThe present study investigated the effect of TiO2 fillers on the mechanical properties of CNT/PMMA composites. TiO2/PMMA/CNT composites were prepared by using twin screw extruder and test samples by injection moulding. Results indicated that incorporation of CNT in PMMA causes decreases in tensile stress, elongation at break, and on impact properties. It is observed that addition of CNT and TiO2 seems to be beneficial in increasing mechanical strength via increasing the interface dispersed phase.
Highlights
Polymer and their composites are finding ever-increasing usage for numerous industrial applications such as bearing material, rollers, seals, gears, cams, wheels and clutches [1]

The PMMA used in the study was Diakon CMG302 supplied by Distrupol Ireland and produced by Lucite International Inc. with MFI = 4.4 g/10 min (ISO 1133), average molecular weight (Mw) 85,000 g/mol. (GPC) and q = 1.18 g/cm3 (ISO 1183)
Summary
Polymer and their composites are finding ever-increasing usage for numerous industrial applications such as bearing material, rollers, seals, gears, cams, wheels and clutches [1]. The bidirectional fabric reinforcement offers a unique solution to the everincreasing demands on the advanced materials in terms of better performance and ease in processing [4]. On account of their high-specific strength and modulus, ease of fabrication and the facility for tailoring in component design, carbon/PMMA composite laminates have been accepted by the aircraft and aerospace industries. Composites and fibre-reinforced polymeric materials are the most attractive because of their abundant usage in mechanical components such as gears, cams, wheels, impellers, brakes, seals, bushes and bearings [10]. One of the commonly used composites is carbon-reinforced PMMA-based polymer material, since it possesses better mechanical and thermal properties [11]
