Fiber-reinforced polymer composites (FRCs) have shown great promise as high strength structural materials due to their high stiffness to weight ratio and their ease in processing. They have found extensive use in aerospace, automotive, construction, and recreational equipment material applications. Research in polymer-based nanocomposites (PNCs) has shown explosive growth in the past decade wit...

Low-velocity strikes are considered as one of the most dangerous load types for composites, especially in aviation. They do not lead to an immediate destruction of a whole detail, but inner damage, provoking a delamination between layers or between fiber and matrix, lowers the material strength and may cause a destruction during the flight. This inner damage can only be noticed via complex stud...

Natural Fibers composites are considered to have potential use as reinforcing material in polymer matrix composites because of their good strength, stiffness, low cost, environmental friendly and biodegradable. In present study, mechanical properties for natural fiber composites were evaluated. Here, areca fiber is used as new natural fiber reinforcement and epoxy resin as matrix. The extracted...

Flax the strongest type bast fiber, possessing excellent mechanical and damping properties. Fatigue properties flax hybridized carbon reinforced were studied. inter-ply hybrid flax-carbon composite compared intra-ply through t...

STATEMENT OF THE PROBLEM Sufficient adhesion between silorane/methacrylate-based composites and methacrylate impregnated glass fiber increases the benefits of fibers and enhances the mechanical and clinical performance of both composites. PURPOSE The aim of this study was to evaluate the compatibility of silorane and methacrylate-based composites with pre-impregnated glass fiber by using flex...

This article proposes a new theory for predicting the crack bridging performance of random short fibers involved in cementitious composites. The current theoretical model for estimating crack bridging performance of Random Short Fiber Reinforced Cement Composites (RSFRCC) under tension is limited to specific constituent properties: friction dominant fiber-matrix interface and complete fiber pul...

Bio-based membranes were obtained using Polyamide 11 (PA11) from renewable sources and a nano-hybrid composed of halloysite nanotubes (HNTs) filled with lysozyme (50 wt % of lysozyme), as a natural antimicrobial molecule. Composites were prepared using an electrospinning process, varying the nano-hybrid loading (i.e., 1.0, 2.5, 5.0 wt %). The morphology of the membranes was investigated through...

This study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. Addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. The glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...
