Due to their light weight and high performance, fiberreinforced composites are being increasingly used in various commercial products in aerospace and automotive industries. Emerging new methods such as liquid composite molding (LCM) and resin transfer molding (RTM) offer an economic, versatile, and efficient means for manufacturing geometrically complex, large composites. RTM process consists ...

–In this research manufacturing of the Kevlar-Mg AZ31B sandwich composite is done. Sandwich prepared using Kevlar fiber and Mg alloy. This manufactured by Vacuum Assisted Resin Transfer Moulding (VARTM) method. method uses vacuum pressure difference causes bonding fiber- metal surface epoxy resin. In alloy act as core material a face skin. fiber-metal will have enhanced mechanical properties th...

In order to avoid the instability of composite materials laminated tube connection between layer and layer, with green basalt fiber as raw material, through reasonable design, special-shaped 3D (three-dimensional) tubular woven fabrics two different thicknesses shapes were fabricated on a semi-automatic sample loom low cost. The composites by VARTM (vacuum assisted resin transfer molding) proce...

A non-autoclave vacuum bag process using atmospheric pressure alone that eliminates the need for external pressure normally supplied by an autoclave or a press is an attractive method for composite fabrication. This type of process does not require large capital expenditures for tooling and processing equipment. In the molding cycle (temperature/pressure profile) for a given composite system, t...

The aim of this study is to evaluate the effect processing temperature on interfacial failure glass/Elium® 150 composites. vacuum assisted resin transfer molding technique (VARTM) was used manufacture composites at three different process temperatures: room (24℃), 50℃ and 80℃. interlaminar shear strength, mode I II fracture toughness laminates were determined by performing short beam (SBS), dou...

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 ...

Integrated leading edge protection (InLEP) is a novel LEP method that involves co-bonding tough thermoplastic to the blade shell of wind turbine made fiber-reinforced thermoset polymer. In process, as result interdiffusion bonded and polymers, an interphase formed between them. An important factor affecting level cure temperature. this work, we investigate influence temperature on morphology bo...

As part of the U.S. Department of Energy’s Wind Partnerships for Advanced Component Technologies (WindPACT) program, Global Energy Concepts LLC (GEC) is performing a study concerning innovations in materials, processes and structural configurations for application to wind turbine blades in the multimegawatt range. The project team for this work includes experts in all areas of wind turbine blad...

In vacuum assisted resin transfer molding (VARTM) process, fiber preform defects result very often from inappropriate placement at edge regions when the fiber preform has three-dimensional shape. The unintentional permeability variation is difficult to detect by viewing through the transparent vacuum bag. In this paper, a method was proposed for detecting the local permeability variation of the...
