Performance analysis of silane grafted nanosilica and aramid fibre-reinforced epoxy composite in dynamic loading and energy application

In this analysis the epoxy resin was strengthened with silane grafted aramid fibre (kevlar) and nanosilica to improve the mechanical and dynamic mechanical behaviour of a turbine blade that was developed and tested. The main goal of this research was to study the role of adding silane-treated aramid fibre and nanosilica particle in epoxy made steam turbine blade. To reduce laminar shear failure under the mechanical and thermal condition, both the nanosilica and aramid fibre were silane-treated. Hand lay-up method was used to produce the composites, which were then post-cured. In line with the dynamic mechanical analysis (DMA) results, the composite prepared using silane-treated nanosilica and aramid fibre had the improved glass transition temperature and storage modulus. Similarly, the steam fluid flow analysis showed that the silane-treated epoxy composites had less thermal and mechanical stress and deformation. These dynamic loading failure resistance epoxy composites could be used in steam turbine blades, armour devices, automobile body parts, and structural applications.
