Development of Glass Fiber Composite with Secondary Inter laminar Nanofiber Optimization and Reinforcement to improve impact strength.

Fiber Reinforced Polymers (FRPs) have demonstrated their structural efficiency since their successful adoption in high-speed trains in Japan during the 1980s. Owing to their lightweight nature, high specific strength, superior corrosion resistance, and cost effectiveness, FRPs have gained extensive applications in the automobile, aerospace, high-speed transportation, and construction industries. The present research focuses on the development and characterization of lightweight, high-strength fiber-glass composite laminates suitable for construction applications. Advanced laminated composites are fabricated using the Vacuum Assisted Resin Transfer Molding (VARTM) process, incorporating electrospun interlaminar nanofibers to enhance mechanical performance. Nano-layered and conventional fiberglass composite laminates are developed and experimentally evaluated, with particular emphasis on impact strength. A comparative assessment is carried out to understand the influence of electrospun nanofiber interlayers on energy absorption and damage resistance. The versatility of the VARTM process allows scope for extending this research to various synthetic fibers and advanced composite systems for future construction applications.
