The quasi-static punch shear behaviors of thermoplastic composites with different polymer matrices and fiber types were investigated. This study was also focused on how much energy absorption capability can be increased by low fiber fractions. Maleic anhydride grafted polypropylene (MA-g-PP) and acrylonitrile butadiene styrene (MA-g-ABS) were used as the matrix material. One layer of aramid, carbon and glass fiber plain weave fabrics was used as the reinforcement material. Quasi-static punch shear test (QS-PST) was applied to the samples to understand the penetration behavior of the samples. The damaged areas were investigated and related to force-displacement curves. The results showed that the neat form of MA-g-PP exhibited 158% more energy absorption than the neat form of MA-g-ABS. In the samples containing one layer of fabric, the highest improvement was observed in the aramid fabric-reinforced MA-g-ABS matrix composites. Aramid fabric increased the energy absorption at a rate of 142.3% in comparison to the neat MA-g-ABS, while carbon fiber fabric and glass fiber fabric increased it by 40% and 63.52%, respectively. Aramid fiber fabric provided no significant improvement in the energy absorption in the MA-g-PP matrix composites, while carbon and glass fiber fabrics contributed to energy absorption at a rate of 48% and 41%, respectively.

The objective of this paper is to experimentally study tensile strength, Impact strength, Flexural strength and Wear Characteristics of the Nano tubular material Halloysite Nanotubes (HNT) into ABS/PC blend with ABS and PC compositions in the ratio 40/60. We have fabricated the Thermoplastic Nanocomposites specimens as per ASTM standards, with the Acrylonitrile Butadiene Styrene (ABS) and Polycarbonate (PC) blend as matrix material and with 1%, 2%, 3%, 4%, 5% and 6% HNT reinforcement material using Co–Rotating Intermeshing Twin Screw Extruder by Melt Compounding. Mechanical Tests were conducted and results were compared with the original ABS/PC blend. Effects of Halloysite Nanotubes reinforcement percentage were discussed in detail. The obtained results suggested that ABS/PC (40/60) blend with 4% reinforcement of Halloysite Nanotubes executed better mechanical properties. SEM is used to study the failure mechanism of the proposed Nano composite.

This research work investigated the effect of the graphene and S-glass fiber on the wear rate of the Al6061 / S-Glass & Graphene particulate MMCs. Metal Matrix Composites (MMC’s) consist of either pure metal or an alloy as the matrix material, while the reinforcement generally a ceramic material. Aluminium composites are considered as one of the advanced engineering materials which have attracted more and more benefits. Now a days these materials are widely used in space shuttle, commercial airlines, electronic substrates, bicycles, automobiles, etc., Among the MMC’s aluminium composites are predominant in use due to their low weight and high strength. The key features of MMC’s are specific strength and stiffness, excellent wear resistance, high electrical and thermal conductivity. Hence, it is proposed to form a new class of composite. The Al 6061(Aluminium alloy 6061) reinforced with graphene and S-glass fiber to form MMCs were investigated. The stir casting technique of liquid metallurgy was used for the fabrication of the composite material. The composite was produced for different percentages of graphene and S-Glass fiber(varying Graphene with constant S-Glass fiber and varying S-Glass fiber with constant Graphene percentage). The specimens were prepared as per ASTM standard size by turning and facing operations to conduct corrosion tests and they were tested using pin on disk apparatus with varying load and speed in different comobinations. Through the results, it is concluded that wear rate increased with the increase in speed and load for every combination of the composite. However with Graphene being the main reinforcement with addition of Graphene wear rate has reduced marginally.

Purpose The purpose of this paper is to develop a coated glass fiber fabric which can be used as the outer shell of firefighters' protective clothing and replace aramid fabric. Design/methodology/approach The silicone resin with excellent heat resistance was selected as the base solution. Silica nanoparticles, mica powder and ferric oxide were added into the coating solution, which was coated on the glass fiber fabrics. The vertical burning, thermal protective performance (TPP) value, second-degree burn time and water repellency of the coated fabrics were characterized. Findings Results showed that the dosages of the thickening filler were in the range 4%–6%; the coating solution has good viscosity. The optimal composition of fillers added in the silicone resin is silica nanoparticles 6%, ferric oxide 5% and mica powder 6%. The TPP value of the optimum coated fabric is 413 kW·s/m2. The second-degree burn time is 4.98 s, which is obviously higher than that of the original glass fiber fabric (3.49 s) and that of the aramid fabric (3.82 s). The coated fabric has better thermal stability than aramid fabric. Originality/value The production cost of this coated glass fiber fabric was much lower than that of the aramid fabric.

The specimens were prepared as per ASTM standard size by turning and facing operations to conduct corrosion tests and they were tested using Brine solution (NaCl solution) with varying normalities. Through the results, it is concluded that the corrosion resistance of the prepared hybrid composites increases as the composition of graphene and S-glass fiber increases, and also corrosion resistance increases with increase in time.
