Compression and permeability properties of multiaxial warp-knit preforms
Padaki, N. V.; Alagirusamy, R.; Deopura, B. L.; Fangueiro, RaúlTextile preform properties such as compression and permeability greatly influence the quality of the composite material and its performance, particularly those prepared by injection moulding techniques like resin transfer moulding (RTM). Directionally oriented warp-knit biaxial, triaxial and quadraxial glass fabrics have been studied for these preform properties. The preform compression properties were tested o...
Multilayer interlocked woven fabrics : simulation of RTM mold filling operation...
Fangueiro, Raúl; Padaki, N. V.; Alagirusamy, R.; Deopura, B. L.The simulation of resin flow during the resin transfer molding (RTM) process through multilayered textile fabric of known permeability and porosity has been attempted in this study. A simple three-dimensional computational fluid dynamics (CFD) simulation model has been developed and the results of the simulation are compared with the experimental RTM resin flow through multilayer interlocked woven structures. A...
Influence of preform interlacement on the low velocity impact behavior of multi...
Fangueiro, Raúl; Padaki, N. V.; Alagirusamy, R.; Deopura, B. L.Impact property of composite material is influenced not only by the type of fiber/matrix, but also by the woven structure of the reinforcement. Presence of 3D fibers in reinforcement is reported to enhance the performance of textile composites in an impact event. This article attempts to study the influence of interlacements in the multilayer woven interlocked 3D structures on the impact properties of the compo...
Studies on preform properties of multilayer interlocked woven structures using ...
Fangueiro, Raúl; Padaki, N. V.; Alagirusamy, R.; Deopura, B. L.Structure property correlation is a critical textile research area explored by various researchers and many factors have been proposed over the years to predict/compare/design the woven fabrics. Cross-over firmness factor (CFF) and floating yarn factor (FYF) have been recently proposed as parameters to understand weave effect on fabric properties (Morino, H., Matsudaira, M. and Furutani, M. (2005). Predicting M...
Tribological behaviour of multilayered textile composites : the effect of recip...
Mathew, M. T.; Padaki, N. V.; Alagirusamy, R.; Deopura, B. L.; Fangueiro, Raúl; Rocha, L. A.; Gomes, J. R.Textile composites have been used for various applications because of their enhanced strength/weight ratio and versatile properties compared to other materials such asmetals. Many studies have investigated the tribological behaviour of textilecomposites, but none have focused onthe tribological characterization of 3D multilayeredwoven reinforced textile composites. Five types of 3-plywoven interlocked structure...
Tribological properties of the directionally oriented warp knit GFRP composites
Mathew, M. T.; Padaki, N. V.; Rocha, L. A.; Gomes, J. R.; Alagirusamy, R.; Deopura, B. L.; Fangueiro, RaúlRecently, directionally oriented warp knit structures have gained prominence as reinforcements in composite materials due to their superior isotropic behaviour compared to other types of textile reinforcements. In the present study, composites prepared from four types of directionally oriented warp knit glass preforms with three different thermoset resins have been considered for the tribological characterisati...
