Abstract In this study, a methodology combining finite element analysis (FEA) and artificial neural network (ANN) through multilayer perceptron architecture was utilized to predict the impact resistance behavior of hybrid non-hybrid fabric reinforced polymer (FRP) composites. A projectile at 250 m s −1 velocity considered for high simulations. The Kevlar, carbon glass fabric-based epoxy composi...

Fiber-reinforced polymer (FRP) has been increasingly applied to steel structures for structural strengthening or crack repair, given its high strength-to-weight ratio and high stiffness-to-weight ratio. Cracks in steel structures are the dominant hidden threats to structural safety. However, it is difficult to monitor structural cracks under FRP coverage and there is little related research. In...

Sprayed FRP is a novel method developed at the University of British Columbia which has been very successful in repairing damaged structures is Sprayed FRP. The key to a successful and optimal usage of FRP in strengthening and rehabilitation is in our ability to understand and effectively engineer SubstrateFRP bond. In this paper, performance of FRP as a repair material is studied by structural...

Abstract The fiber reinforced polymer (FRP) armor composites are kinds of composite materials specially designed and manufactured to prevent the penetration high-speed bullets fragments. FRP commonly composed reinforcing fibers, resin matrix their interfacial structures. vinyl ester (VER) is a kind thermosetting applied in field high performance bulletproof composites. However, VER has problem ...

This talk starts with a review of the different strategies to incorporate nanocarbons (CNTs, graphene) inpolymer matrices and their relative merit in terms of mechanical reinforcement, improvement inelectrical/thermal conductivity and emergence of other functional properties, such as sensingcapabilities [1] [2]. Three types of nanocomposites are discussed: the first type corresponds...

Resin transfer molding (RTM) is a popular manufacturing technique that produces fiber reinforced polymer (FRP) composites. In this paper, a model-assisted flow front control system is developed based on real-time estimation of permeability/porosity ratio using the information acquired by a visualization system. In the proposed control system, a radial basis function (RBF) network meta-model is ...

This paper presents a study on interfacial stresses of a concrete column confined by fiber-reinforced plastic (FRP) plate, which has been widely applied in the civil engineering for rehabilitation and retrofitting of conventional structures. It is assumed that both the FRP plate and concrete structures are elastic and the interface between them is perfectly bonded. An analytical model for analy...

Pultrusion is a high-volume manufacturing process for fiber-reinforced polymer (FRP) composites ensuring high strength and quality products. However, research studies are very limited on the fatigue behavior of these products, especially with unidirectional fiber alignment. This study investigates pultruded glass FRP (GFRP) volume fraction ( V f = 65 % $$ {V}_f=65\% ). Tension–tension loading w...

UNLABELLED RP170, 1-(2-hydroxy-1-[hydroxymethyl]ethoxy)methyl-2-nitroimidazole, is a new hypoxic radiosensitizer. We recently succeeded in labeling this compound with 18F to make 18F-FRP170, 1-(2-fluoro-1-[hydroxymethyl]ethoxy)methyl-2-nitroimidazole. In this study, we attempted to visualize the ischemic but viable myocardium of rats as hot-spot images using 18F-FRP170. We also compared the dis...

Near-real time estimates of biomass burning emissions are important for air quality monitoring and forecasting. We present here the preliminary analysis of global biomass burning emission product (GBBEP) produced from geostationary-satellite-derived fire radiative power (FRP) in near-real time. Specifically, the FRP is retrieved at an interval of 15 to 30 minutes using WF_ABBA_V65 (Wildfire Aut...
