However, due to several stringent requirements on ductility, this has affected the performance of FRP composites for the structural applications. Therefore, hybrid composites, which combine two or more fiber reinforcements, have been introduced in order to overcome the short of traditional FRP composites. This paper investigates the mechanical properties of three different arrangements of hybrid composites made from glass fiber (plain-woven and stitched bi-axial ±45˚) and plain-woven carbon fiber. Vacuum assisted resin transfer moulding method was employed to fabricate the hybrid composite panels. Mechanical properties such as tensile strength, flexural strength and volume fraction of the hybrid composites were determined per ASTM standards. Experimental results indicate that the [CWW] 6 arrangement, where C and W are weaved carbon fiber and glass fiber respectively, were superior in terms of mechanical properties.

However, these materials have inadequate wear resistance in different abrasive wear environment such as gears, bearings and rollers. Thus, the evaluation and improvement of wear properties of polymer matrix composites is necessary for structural and abrasive wear environment. In this article, the three body abrasive wear properties of glass/carbon reinforced hybrid composites are investigated with different operating conditions. The Box-Behnken Design of Experiment was used to conduct the experiments. A polynomial mathematical model has been developed through Response Surface Methodology (RSM). The model predicted optimum conditions for minimum specific wear rate of the hybrid composite ([G3C2] s) is applied load of 33N and sliding distance of 1221m. Furthermore, a confirmation test has been performed experimentally and found a good agreement between them.

Carbon fiber reinforced polymer composites (CRPC) are stronger than glass fiber reinforced polymer composites (GRPC). However, the cost of carbon fiber is around four times than glass fiber. Therefore, there is a need to evaluate the mechanical properties of glass/carbon hybrid composites to meet the design requirements and reduce the cost. In this article the effect of glass/carbon fiber ply sequence on mechanical properties were investigated experimentally. Two types of hybrid composites were considered; i.e [G3C2] S & [C2G3] S and mechanical properties were evaluated. The composites were fabricated by hand-layup method. The results revealed that the tensile strength has been improved in [G3C2] S hybrid composite by 11.5% as compared to [C2G3] S composites. The fracture toughness and flexural strength of [C2G3] S has been improved by 52.4% and 22.9% respectively as compared to [G3C2]s composites. Hence, the mechanical properties are sensitive to inter-ply sequence even if the weight fraction of each fiber types is constant.
