The VOC emission characteristics of the typical fiber-reinforced plastics (FRPs) industry were studied for an assessment impact on environment. results showed that emissions FRP mainly come from grille, sheet, winding, molding, and pultrusion process links, including ketones, aldehydes, alcohols, benzene series. series’ concentration represented by styrene was much higher than other species. ge...

Among the several available techniques to produce the braided composite rods for construction industry, nidltrusion process is becoming the most widespread and cost-effective continuous processing technique. The work mentions the influence of carboxyl functionalized multiwalled carbon nanotubes (MWCNTs) on the maximum speed of manufacturing process. The epoxy polymer is diglycidyl ether of bisp...

The structural feasibility of using a pultrusion carbon-fibre-reinforced polymers (CFRP) for the lightweight design mast overhead line railway electrification was investigated and simulated. Material characterisation undertaken three-point bending finite element analysis to identify orthotropic properties pultruded tubes designed composite electrification. An innovative proposed verified simula...

The cure kinetics of resin, heat capacity, and thermal conductivity reinforcing materials uncured mass dictate the ultimate curing reinforced thermosets manufactured component. In this study, degree conversion from capacity by “Lumry Eyring Model” order reaction multi-regression technique using “Borchardt Daniels are calculated in finding () resin. Experimental results differential scanning cal...

Pultrusion is one of several manufacturing processes for reinforced polymer composites. In this process fibers are continuously pulled through a resin bath and, after impregnation, the fiber-resin assembly is cured in a heated forming die. In order to obtain a polymeric composite with good properties (high and uniform degree of cure) and a process with a minimum of wasted energy, an optimizatio...

Process-induced stress and deformation are critical factors when ensuring product quality structural integrity of composite profiles manufactured using thermoset pultrusion processes. In this paper, we present a new steady-state 3D-Eulerian numerical framework that enables 9–35 times faster computations compared to the current state-of-the-art quasi-static 3D-methods. addition, show how process...

From the last few decades, study of natural fiber composite materials has been gaining strong attention among researchers, scientists, and engineers. Natural are becoming good alternatives to conventional because their lightweight, high specific strength, low thermal expansion, eco-friendly, manufacturing cost, nonabrasive bio-degradable characteristics. It is proven that a great alternative sy...

The bearing capacity of piles on the ground is one main characteristics pile foundations, which responsible for its interaction with ground. This characteristic depends many factors: granulometric composition soil, moisture content, con-sistency, texture, as well type and properties material. One charac-teristics material surface roughness. In studies, dependence angle friction soil against val...
