Abstract

The performance of composite materials is influenced largely by adding organic or inorganic nanoparticles. The composite properties also depend on the fiber/matrix interface bonding. The present article focuses on the influence of basalt fiber surface modifications using hybrid sizings (silane/and silica nanoparticles (SNPs)) and matrix modifications by adding SNPs in the epoxy resin are studied. Vacuum-assisted resin infusion molding (VARIM) was used to fabricate the basalt fiber/epoxy composites. First, the commercial fibers were washed in acetone to remove the commercial sizing; thereafter, a hybrid sizing (3-Glycidyloxypropyl) trimethoxysilane (GPMS)/SNP was applied using the dip-coating method. The SNPs were dispersed using homogenization and probe sonication before infusion. There is an improvement of about 9.05% and 11.33% in the tensile strength and 2.40% and 4.13% in the tensile modulus of as-received basalt fibers with modified epoxy (ABF/EPSNP) and sized basalt fibers with as-received epoxy resin (SBF/EP) composites, respectively. The flexural strength and modulus have improved by about 30% and 8.5%, respectively. Failure mechanisms were analyzed using scanning electron microscopy. From the current study, it was found that surface modifications could result in better composite performance.

期刊介绍： Applied Composite Materials is an international journal dedicated to the publication of original full-length papers, review articles and short communications of the highest quality that advance the development and application of engineering composite materials. Its articles identify problems that limit the performance and reliability of the composite material and composite part; and propose solutions that lead to innovation in design and the successful exploitation and commercialization of composite materials across the widest spectrum of engineering uses. The main focus is on the quantitative descriptions of material systems and processing routes. Coverage includes management of time-dependent changes in microscopic and macroscopic structure and its exploitation from the material''s conception through to its eventual obsolescence.
