Abstract Glass fiber-reinforced polymer materials have been effectively used in civil aviation aircraft, but due to low electrical conductivity, a large area of ablation damage will occur after lightning strikes, which greatly threatens the safety aircrafts. Based on this, coupled electrical-thermal finite element analysis model for glass fiber reinforced is established, and results are compare...

statement of problem: fracture strength of a denture base resin is of great concern, and many approaches have been used to strengthen acrylic resin dentures. purpose: the aim of this study was to measure the transverse strength of a heat polymerized acrylic resin, after reinforcement with metal wire and two types of glass fibers. materials and methods: forty rectangular specimens (65.0×10.0×3.3...

The objective of this study was to experimentally evaluate the fatigue limit 90° unidirectional carbon fiber reinforced plastic (CFRP) laminates. very high-cycle properties specimens were evaluated using ultrasonic and electromagnetic testing machines. Ultrasonic tests conducted obtain under giga-cycle regime. specimen geometry designed resonate at 20 kHz, consisted CFRP laminate a metal tab co...

The efficient use of fiber reinforced polymer matrix composites in load-carrying structures requires detailed analyses to assess their mechanical performance, cost, and weight saving aspects. To accurately analyze the cyclic fatigue life of composite laminates, the influence of the physical non-linearity of the unidirectional lamina in the cyclic fatigue life analysis was examined using enhance...

With the increasing requirements of automotive lightweighting, metal/CFRP laminates are increasingly used. In this paper, Al/CFRP were prepared using an integrated hot press curing method, and optimum conditions determined single-lap shear test at 130 °C for 45 min. The effects fiber lay-up, forming speed, metal layer thickness on bending springback investigated V-shaped Abaqus finite element a...

A computational study is performed to determine the contribution to ultrasound attenuation in carbon fiber reinforced polymer composite laminates of linear elastic scattering by matrix micro-cracking. Multiple scattering approximations are benchmarked against exact computational approaches. Results support linear scattering as the source of observed increased attenuation in the presence of micr...

The use of fiber reinforced materials such as randomly-oriented strands has grown in recent years, especially for manufacturing of aerospace composite structures. This growth is mainly due to their advantageous properties: they are lighter and more resistant to corrosion when compared to metals and are more easily shaped than continuous fiber composites. The resistance and stiffness of these ma...
