The aim of this paper is to study the effect of silane treatment on woven banana fabric based unsaturated polyester resin composites. The fabric was treated with vinyl triethoxysilane. Woven banana fabric (WBF) reinforced unsaturated polyester resin (UPR) composites were fabricated by hand lay-up technique. The fabric content in the composite was kept constant to 35 %. The variation in the mech...

This work presents a computational material model of flexible woven fabric for finite element impact analysis and simulation. The model is implemented in the nonlinear dynamic explicit finite element code LSDYNA. The material model derivation utilizes the micro-mechanical approach and the homogenization technique usually used in composite material models. The model accounts for reorientation of...

reduced cost, widespread expertise in Ethernetrelated protocols, and simplicity of using a single fabric. However, the transition to a unified Ethernet fabric requires resolving several major challenges, including efficient implementation of the dominant protocol layers—for example, iSCSI, TCP, RDMA, and SSL—at high data rates; advanced quality of service to ensure that a unified fabric works a...

The application of Butane tetra carboxylic acid/nano titanium dioxide [(BTCA)/Nano TiO2 (NTO)] on cotton fabric has been used to cross-linked cellulose, and yield higher NTO absorption and enhanced selfcleaning properties. In this research, the synergistic effect of BTCA and NTO on antibacterial properties of the cotton fabric was investigated. The NTO particles were stabilized on the cotton su...

In the paper, a cross-layer optimization between application layer and fabric layer is proposed. The aim is to optimize the end-to-end quality of the dynamic grid application as well as efficiently utilizing the grid resources. The application layer QoS and fabric layer QoS are closely interrelated in Grids since the upper layer service is based on the lower level’s capabilities. A fabric level...

In this paper, fabric density influence on the shielding effectiveness of electromagnetic shielding fabric is studied. A series of blended shielding fabrics are tested using a waveguide tube testing method to obtain the shielding effectiveness with different density. Experimental results show that the shielding effectiveness increases with the increase of fabric density, and there are two rapid...

This paper is devoted to the mechanics, modelling and analysis of fabric-reinforced composites and structural components. A theoretical and experimental characterisation of elastic properties of the textile composites is considered. Typical stress-strain diagrams for fibreglass fabric composites and composites reinforced with knitted fabrics loaded in tension at different angles are presented. ...

The present paper is concerned with modelling damage and fracture in notched woven fabric composites. Previous experimental work has shown that damage at a notch in a variety of GFRP and CFRP composites based on woven fabric reinforcement comprises matrix damage and fibre tow fracture along the plane of maximum stress. It is these experimental observations that inform the failure modelling deve...
