Regenerated cellulose fibres are an important part of the forest industry, and they can be used in form fabrics as reinforcement materials. Similar to natural (NFs), such flax, hemp jute, that widely automotive these possess good potential for semi-structural applications. In this work, mechanical properties regenerated fabric-reinforced poly methyl methacrylate (PMMA) (Elium®) composite were i...
During the past 15 years NASA has taken the lead role in exploiting the benefits of textile reinforced composite materials for application to aircraft structures. The NASA Advanced Composites Technology (ACT) program was started in 1989 to develop composite primary structures for commercial transport airplanes with costs that are competitive with metal structures. As part of this program, sever...
Turbine blades form the main component for energy generation in renewable technologies such as wind and tidal energy. Non-crimp fabric (NCF) based fibre reinforced composite materials, with E-glass carbon fibres have been widely used materials blades. However, sustainable composites using naturally derived basalt, are being developed to reduce environmental impact. Basalt require no chemical ad...
INTRODUCTION Composite materials are often used to reduce the weight of structures. In the automotive industry weight reduction is important because fuel consumption is directly related to vehicular weight. There is an increased concern for occupant safety during roadway accidents. Metals are currently used in car frames and integrated frame-body structures, and these and other metallic compone...
The drag coefficients on discs rotating in a cylindrical tank has studied in relation to the nature of a composite coating attached to the underside of the disc, and direct comparisons were made with refrence discs of identical geometry which were completely rigid. The composite coating was formed by: (1) bondig of velvet fabric to the metal disc with velour face outward, (2) casting a premixed...
Usually, energy and structural improvements for historic masonry buildings are addressed separately using distinct methods protocols. This paper covers an integrated assessment of new composite materials to reduce the seismic vulnerability while complying with sustainable conservation requirements, emissions’ reduction, savings. Firstly, this study focused on selecting suitable thermal mortars ...
This paper presents an innovative route to fabricate conformal patch antenna arrays based on a flexible mesh-style conductive fabric / E-glass fiber composite laminate with improved performance at microwaves. On the one hand, ohmic loss in array is restricted by integrating highly into and using it as feeding lines radiating elements after its precise machining laser technology. other dielectri...
This study investigated the effect of fabric parameters on crack propagation in plain-woven e-glass reinforced epoxy composite plates. Through numerical analyses, contributes to understanding structure and adopting a more precise approach design materials. The yarn fiber volume fraction, shear angle, spacing were selected as variables for fabric, material properties determined each parameter us...
