Twenty plies, woven carbon fiber/epoxy matrix, virgin, and Nylon 6,6 electrospun nanofiber interleaved composite laminate beams are tested under Modes I II fracture mechanic to assess the effect of nanointerleave on global behavior laminate. Aim work is study geometrical features nanoreinforce mechanical response a subjected loads. Nanofiber orientation, nanolayer thickness, diameter have been considered. From experiments, parameters extracted used compare configurations. The highlights...
Nylon 6,6 nanofibers were interleaved in the mid-plane of glass fiber/epoxy matrix composite laminates for Mode I and II fracture mechanic tests. The present study investigates effect on laminates’ mechanical response. Results showed that improved specimen’s behavior: initial energy release rates G IC IIC increased 62% 109%, respectively, when nanofibrous interlayer was used. Scanning electron microscope micrographs nanofiber bridging mechanism enhances performances nanomodified specimens,...
Nylon 6,6 electrospun nanofibrous membranes interleaved in "high performance" Carbon Fiber Reinforced Polymer (CFRP) laminates have been proposed as a means to provide high threshold value delamination on structural sites where composites are more prone develop such failure. A model, highly crosslinked, thus inherently brittle, epoxy matrix was selected for its Young's modulus and glass transition temperature exceeding 250°C. The influence of the nanofibers curing behavior thermal dynamic...
Nylon 6,6 nanofibers manufactured by means of electrospinning have been used to interleave Mode II fracture mechanics glass and carbon unidirectional fiber composite specimens. The aim this work was study the effect materials in their ability reinforce interleave. Experimental testing carried out on specimens with a nanofibrous mat interleaved into delaminated interface. Specimens 10, 16 18 layers were tested. Results demonstrated that different between two play an important role...
Design of electric motors, especially for automotive applications where early design choices have significant impacts on the final results, in terms both cost and performances, is a matter primary importance, with direct consequences entire vehicle. Common practice lacks simple, yet reliable, analytical method to evaluate vibration noise emission permanent magnet synchronous motors (PMSMs), this gap that work here proposed aims fill. In particular, vehicles requirements added opportunity...
Composite materials have experienced a significant increase in demand over the past five decades. This growing usage has led to considerable production of waste, particularly from prepreg scraps, which can account for up 35% purchased material. paper explores recycling scraps by cutting them into smaller patches and reassembling new sheets. The study follows dual approach: mechanical testing on two different types samples is presented, along with numerical modeling strategies designed...
Plain and nanofiber-interleaved glass/epoxy laminates clamped according to ASTM D7136 tested under impact loading assess the improvement in resistance of composite that have been interleaved by electrospun polyvinylidene fluoride (PVDF) nanofibers with two different thicknesses.Composite specimens stacking sequence [0/90/0/90]S were impacted at energy 5J.Variation characteristics such as maximum contact load, deflection, time, absorbed are depicted figures.The results showed PVDF not a good...
Abstract The imperative shift toward sustainable development mandates a revolutionary transformation in the transportation sector. While transition from internal combustion engines to electric motors represents pivotal step, its ecological impact may fall short of expectations. This undertaking is motivated by recognition that truly impactful necessitates intricate strategies, addressing resource consumption during manufacturing and minimizing post-use waste. literature review dedicated...
This paper considers a vibration-based damage assessment approach which is based on the general idea for signal cross-correlation. Here method demonstrated and validated composite laminate beam it applied purposes of delamination in structures. The uses two measures cross-correlation between vibration signals measured different points structure order to diagnose delamination. linear as well new measure nonlinear cross-correlation, mutual information, are introduced assessment. comparison...
This paper presents an investigation on fracture behavior of carbon/epoxy composite laminates interleaved with electrospun nanofibers. Three different mats were manufactured and interleaved, using only polyvinylidene fluoride (PVDF), polysulfone (PSF), their combination. Mode-I Mode-II mechanics tests conducted virgin nanomodified samples, the results showed that PVDF PSF nanofibers enhance critical energy release rate (GIC) by 66% 51%, respectively, while a combination two registered 78%...
