Epoxy resin based on diglycidyl ether of bisphenol-A (DGEBA type) was toughened with varying weight fractions, i.e., from 0 to 10% of thermoplastic polycarbonate (PC). Compression and impact properties of the toughened resin matrix were investigated. Epoxy containing 6 wt% of PC showed highest strength and modulus. Further, composites were prepared with varying percentage viz., 30 to 60 wt% of silane coupling agent treated granite particle (TGP) loading with 6 wt% PC toughened epoxy resin as matrix. Mechanical properties such as compression and impact behaviour of these composites were assessed and catalogued. Fractographic studies of the composites have been carried out using scanning electron microscopy (SEM).

“…The importance of the work is to utilize granite stone waste which is anti-biodegradable and causing various problems if it mixes into the air or when it is left on the ground. Currently, industrial waste-reinforced polymer composites are gaining researchers and industrialist's attention [1][2][3]. Yet little research done on the use of waste granite powder as the filler in thermosets has been published so far.…”

The potential of using granite dust as reinforcement into polybenzoxazine matrix was investigated. In this article, novel granite powder waste-reinforced bisphenol-A aniline-based benzoxazine composites were prepared using solution blending technique by varying the content of granite powder from 10 to 40 wt%. The effect of the granite powder content on the thermal, structural, dimensional, and morphological properties of granite powder/polybenzoxazine composites have been investigated. Thermogravimetric analysis (TGA) was performed on the composite samples. Char yield of the composites increased from 44.55 to 67.70% for increasing filler content from 10 to 40wt%, whereas 22% for pure polybenzoxazine. The maximum weight loss temperatures of the composites were analyzed from derivative of thermogravimetric analysis (DTG). Limiting oxygen index (LOI) values also increased as granite powder content increased. Structural properties of benzoxazine, polybenzoxazine, and composites were observed with Fourier-transform infrared spectroscopy (FTIR). Dimensional stability of the composites was investigated through the water absorption test up to 30 days. The composites exhibited zero percent water absorption. Micro-hardness of the composites increased from 17.45 to 78.66% for increasing filler content from 10-40 wt% when compared with pristine polybenzoxazine. The morphological analysis using scanning electron microscopy (SEM) showed the distribution of filler, aggregate formation, compatibility between polybenzoxazine and granite powder. Overall, the importance of using granite powder waste as reinforcement in polybenzoxazine composites revealed from results of the structural, dimensional, and morphological analysis along with the improvement in thermal properties and micro-hardness.

“…So such waste material needs to be utilized meaningfully in an economic way. At the present time, development of some polymer based composites with industrial waste materials (with no end use) as fillers / reinforcements has gained the popularity [1][2][3]. But so far little development has been reported on the utilization of waste granite powder as the filler in thermosets.…”

Journal of Advanced Chemical EngineeringPaul et al., J Adv Chem Eng 2017, 7:1 DOI: 10.4172/2090 Volume AbstractComposite materials are now widely used in engineering application and the scope of its application is widespread mainly for its contrapuntal properties. In this research work composites were prepared by crosslinking the polyester resin with Methyl Ethyl Ketone Peroxide and finally reinforced with the Granite scrap powder. Granite stone as filler was used at 20%, 30%, 40% and 50% with respect to the weight of unsaturated polyester resin with styrene monomer at 7.5% as constant basis mentioning that 0% sample (without Granite Filler) was also prepared to compare the results with it. Thermal analysis of the prepared composite such as Thermo Gravimetric Analysis (TGA), Thermo-mechanical Analysis (TMA) and Thermal Conductivity of the composites were analyzed along with the SEM analysis to find out correlation between thermal properties with composite surface topology. Thermo gravimetric analysis is done to determine the kinetics of thermal degradation and Thermo mechanical analysis is to determine expansion co-efficient along with Tg of polyester resin and granite blends composite. To avoid the thermo-oxidative degradation, thermal analysis was carried out for samples in nitrogen atmosphere at heating rates of 20°C/min. Thermal Conductivity analysis is performed to determine the ability of the composite to conduct heat at various temperatures.
