Abstract
::
Composite materials have replaced traditional material because of their superior properties like low density, high strength to weight ratio, good fatigue and corrosion resistance. However, on the contrary, these properties are degraded when exposed to harsh environmental conditions. In recent days, various firms have attracted advanced and high-performance materials, which meet the global market requirements like lightweight, economical, safety and long durability, especially in automotive and structural applications. Furthermore, producing these high-performance materials can be possible with the adoption of new processing techniques and/or different material combinations. The present investigation's objective deals with developing advanced composite materials by introducing polymer hybridization (GPH) and/or novel Epoxy/Vinyl ester Interpenetrating Polymer Network (EVIPN). The new processing technique and novel polymeric material resulted in improved flexural and Interlaminar shear strength (ILSS) properties than that of both glass fiber reinforced epoxy (GE) and glass fiber reinforced vinyl ester (GVE) composites. The role of cure kinetics on the flexural behavior of all experimented composites at different post cure temperatures (140, 170, 200 and 230 °C for 6 h duration) and also elucidates the comparative analysis on the mechanical behavior of GE, GVE, GPH and GEVIPN composite. Among all these composites as mentioned above, highest flexural strength and interlaminar shear strength properties have been recorded by the 200 °C post-cured GPH composite leading to 10.87% and 18.76% increment respectively and 200 °C post-cured GEVIPN composite leading to 13.43% and 21.83% increment respectively, compared to GE composite. Further, thermomechanical characterization has been done to know the viscoelastic behaviour of the experimented (GPH and GEVIPN) composite post cured at different temperatures using dynamic mechanical thermal analysis. The fracture morphology of flexural tested composite samples demonstrated a combination of failure modes. Relevant information on the chemical restructuring and fracture morphology of experimented composite material using FTIR and SEM has also been studied.
