摘要: This work details an experimental investigation on understanding the effects of multi-walled carbon nanotubes (MWCNTs) tensile and flexural properties basalt fiber (BF)/epoxy laminated composites. As a first step, surface MWCNTs was modified with silane coupling agent namely 3- Glycidoxypropyltrimethoxysilane (3-GPTS). Fourier transform infrared (FT-IR) data confirmed reaction mechanism between compound MWCNTs. 3-GPTS/MWCNTs various loadings (0, 0.1, 0.3 0.5 wt.%) were added to epoxy resin via mechanical ultra-sonication routes. The resultant mixtures then utilized fabricate MWCNT/woven BF/epoxy nanocomposites using hand-layup technique. Mechanical composites investigated under loadings. Also, field-emission scanning electron microscope (FESEM) used study distribution level in matrix as well fracture surfaces specimens. results revealed that at filler loading wt.% 3-GPTS/MWCNTs, maximum improvements strengths energy absorption obtained. Besides, moduli enhanced continually by increasing content. microscopic investigations verified this subject addition composite improves BF- interface yielding properties.
