SHORT BEAM STRENGTH OF LAMINATED FIBERGLASS COMPOSITE WITH AND WITHOUT ELECTOSPUN TEOS NANOFIBERS

摘要

Fracture toughness of the laminated fiberglass composite is an important property and hasrnsignificant impact in the structural applications. In this paper, additional epoxy resin film wasrnadded in conjunction with Tetraethyl orthisilicate (TEOS) electrospun nanofibers (ENFs) betweenrnthe plies of the laminates.The laminated fiberglass composite were fabricated using vacuumrnbagging method with and without electrospun nanofibers interleaved between laminates. The shortrnbeam strength of the nanoengineered laminated composite was investigated for four stackingrnsequences. The study shows that interleaving of TEOS ENFs between the laminates enhancedrnstrain energy absorbed before complete failure and fracture toughness of tested glass fiberrnreinforced polymeric composites increased upto 30% and the short beam strength improved byrn16%.
