“…Surface hardness falls in the range of 96–98 and 95–98 for unexposed epoxy and polyester glass fiber laminates, respectively. The values obtained indicate that both the systems were well cured because both the systems have a hardness value greater than 95 9, 11. A slight reduction of about 2–4% in Shore D hardness is observed for exposed systems, except for 70 and 100°C heat ageing.…”

Glass-fiber-reinforced epoxy and unsaturated polyester (UPE) composites were fabricated from diglycidyl ether of bisphenol-A (DGEBA) using 10% diethyl triamine (DETA) as a hardener and unsaturated polyester (UPE) using 1.5% each of methyl ethyl ketone peroxide (MEKP) and cobalt naphthanate as a catalyst and an accelerator, respectively. The fabricated composites were exposed to different aggressive environments, such as heat, water ageing, lubricating oil, fuel, and seawater. The exposed specimens were characterized by physical, chemical, mechanical, and thermal properties. A marginal increase (12%) in the mechanical properties in heat ageing, but a reduction in properties in other exposed systems of the epoxy and polyester glassfiber-reinforced (GFRP) composites, were observed. ReinforcementE-glass fiber cloth, of 0.315-mm thickness, 0°/90°b idirectional, plain weave with specifications IS-5746 type 1, variety 2, was used.

“…From the table, it is evident that porosity values lie in the range of 4.22–4.89% and are in the expected range. The hardness is a measure of resistance to indentation and, hence, will not be greatly influenced by the matrix 11. The shore D hardness value indicates the percentage of cure 9.…”

In this work, the influence of precipitated nano calcium carbonate (PNCC) on the mechanical and thermal properties of epoxy/glass fiber (GF) laminates was studied. The mechanical properties of the epoxy/GF/PNCC composites were characterized by flexural and impact tests. The fracture toughness of the epoxy hybrid composites was evaluated by the principle of linear elastic fracture mechanics via single-edge notched bending tests. The thermal properties of the epoxy hybrid composites were studied using dynamic mechanical analyzer (DMA) and thermogravimetric analyzer (TGA). The flexural properties, impact strength, and fracture toughness of the epoxy/GF laminates were increased profoundly in the presence of PNCC. Additionally, from the DMA and TGA results, it was found that the storage modulus and thermal decomposition temperature of the epoxy/GF increased remarkably with the addition of PNCC.
