Abstract Polymer composites with lightweight, ultralow dielectric constant, excellent thermal insulation and mechanical properties are in high demand aerospace, transport, wireless communications other fields. In this work, the three‐dimensional woven Kevlar/glass hybrid (3DKGC) strength, were obtained Kevlar fiber glass as raw materials. The results showed that volume content of air 3DKGC is over 82% density low 0.29 g·cm −3 , while compression strength 7.68 MPa. exhibits an ultra‐low...
Abstract In this study, to further improve the anti‐impact property of 3D woven spacer composites (3DWSC), three kinds integrated 3DWSC with double‐layer cores assembled at different height combinations 4 + 8 mm, 6 and were designed prepared. And impact performances post‐impact lateral compressive properties resulting investigated compared single‐layer same height. The results show that among combinations, 3DWSC‐4 has highest contact force value 2454.33 N 10 J, which is 90.60% higher than...
Abstract Thermoplastic composites have a high application demand in aerospace, marine military and other cutting‐edge industry. However, it poses considerable obstacle achieving three‐dimensional (3D) thermoplastic because of the inadequate infiltration highly viscous resins. In this paper, high‐toughness Polyetheretherketone (PEEK) resin‐based 3D orthogonal carbon fiber were designed obtained. Low‐velocity impact test was conducted on woven composite (3DOWC) under energy levels 5 10 J, its...
Abstract Three‐dimensional woven spacer composites (3DWSCs) with lightweight and excellent mechanical properties have promising application in communication, transportation, aerospace other fields. However, traditional single‐layer 3DWSCs exhibit insufficient strength, especially when dealing high thickness, as the pile yarns tend to buckle. In this study, inspired by structural features of Thalia dealbata , 3D integrated double‐layer glass fiber/epoxy resin mimicking were fabricated....
Abstract In this work, a new type of epoxy foam‐filled 3D woven spacer composites (FF‐3DWSCs) was designed and manufactured by self‐made loom foaming technology. The low velocity impact behaviors, residual compressive properties strengthening mechanisms foam were systemically investigated. As the results, FF‐3DWSCs showed higher load 4000–5200 N than that (3DWSCs) (2800–4300 N) at energy from 10 to 40 J. strength (23.85 MPa) maintained about 80% after 30 J impact. Due good compatibility...
