In the present study EP142-C510-50 woven carbon fiber composite was investigated from structural/ mechanical point of view aiming manufacturing parts for aeronautical industry. The composites were obtained by hand lay-up process. Prior to mechanical tests, the cure reaction results of composite resins specimens were analyzed by using DSC technique. The EP142 epoxy matrix was cured/polymerized a...

This article reports the development of a novel embedded acoustic waveguide sensor concept for monitoring the curing process and online health of composite structures. A sleevedwaveguide embedded in the composite is proposed to confine guidedwaves in one dimension, with leakage to the surroundingmedia only through specially created openings, thus enhancing the capability to inspect large struct...

A simple physically-based model for the abrasive wear of composite materials is presented based on the mechanics and mechanisms associated with sliding wear in soft (ductile)matrix composites containing hard (brittle) reinforcement particles. The model is based on the assumption that any portion of the reinforcement that is removed as wear debris cannot contribute to the wear resistance of the ...

To improve the dispersion effectiveness of carbon nanotubes (CNTs) in epoxy and adhesion resulted composites on steel substrates, this paper proposed to surface treat CNTs using carboxymethyl cellulose (CMC) epoxy-CNTs composite. The characterizations properties reinforced by CMC treated were then systematically investigated. with three different weight fractions (0.5%, 1%, 2%) CMCs their compo...

This study is focused on the influence of a modified matrix glass fiber reinforced laminates, which inherently have different material properties than carbon composites. For this we green epoxy resin with 2.5wt% based fillers (synthesized graphene nanopellets, and milled recycled fibres), were subsequently applied to multifilaments, vacuum cured obtain fiber/epoxy UD laminates. The prepared sam...

This paper present finite element analysis on the internal structure of wind turbine to examined deflection and stress distribution. The was modeled as a cantilever box beam with constant cross section along length. dimension set according original design 10 MW AVATAR (Advanced Aerodynamic Tools for Large Rotors) turbine. proposed materials were unidirectional thin-ply TC35/Epoxy M55/Epoxy carbon...

adhesive bonding technology is being used in a variety of modern industries, including the automotive, aerospace, maritime, construction, defense and so on. on the other side, polymeric nano - composites attracted both academic and industrial interests in the past decades. the scope of this paper is experimental investigation on the effects of the addition of alpha-alumina nanoparticles to the ...

the idea of combining low weight and good mechanical properties has led to efforts to develop a new light fiber/metal laminate (fml) in the last decade. fmls are hybrid composites consisting of alternating thin layers of metal sheets and fiber-reinforced epoxy prepregs. in this study, the effect of fiber orientation on tensile properties of this material is investigated both analytically and ex...

This research aimed to evaluate the thermal properties of new formulations of phase change materials (PCMs)-epoxy composites, containing a thickening agent and a thermally conductive phase. The composite specimens produced consisted of composites fabricated using (a) inorganic PCMs (hydrated salts), epoxy resins and aluminum particulates or (b) organic PCM (paraffin), epoxy resins, and copper p...
