We investigated the effects of hygrothermal aging on the tension–tension fatigue behavior of unidirectional (UD) glass/polydicyclopentadiene (pDCPD) composites. Samples were immersed in deionized (DI) water and salt water, and glass/epoxy composites were used as a benchmark for comparison. Composites of pDCPD showed less water uptake and superior fatigue performance compared to similarly aged e...

Fibre reinforced plastics are increasing their importance as one of the most interesting groups of material on account of their low weight, high strength and stiffness. To obtain good quality holes, it is important to identify the type of material, ply stacking sequence and fibre orientation. In this paper, the drilling of quasi-isotropic hybrid carbon+glass/epoxy plates is analyzed. Two commer...

The objective of this research was to evaluate the effect of kenaf fiber orientation and furnish formulation on the properties of laminated natural fiber–polymer composites (LNPC). The uniaxial fiber orientation provided property enhancement of the LNPC. The randomly oriented kenaf fibers, regardless of fiber contents in the laminates, provided an equal performance compared to the composites ma...

Abstract This work investigated effect of glass fibre fabric structures, feedstock feed rate and screen size on specific shredding energy reinforced plastics (GFRP) waste via a two-level factorial design experiment study. Four types structure, i.e. unidirectional (UD), biaxial (BIAX), triaxial (TRIAX) chopped strand mat (CSM), were impregnated separately with unsaturated polyester resin to manu...

In the present study, method of ultrasonic welding of plastics is used to join the overlap of Polypropylene composites reinforced with glass fiber. The effects of process parameters, including time, pressure, vibration amplitude and amount of glass in composite on strength of welds. To reduce the number of tests and cost, the effect of changing parameters on strength was examined through Box-Be...

The composite materials are normally made of reinforcements and resins. High-performance composites generally termed hybrid materials. Generally, fiber-reinforced laminates very weak in their out-of-plane properties, to address this issue unidirectional (UD) Glass prepared by modifying epoxy matrix using plasma-treated multi-walled carbon nanotubes (MWCNTs) compared with low-cost micro fillers ...
