Characterization of fabric tensile loading curve in nonlinear region related to their structure; Part1: woven fabric

Influence of the Dry Woven Fabrics Meso-structure on Fabric/fabric Contact Behaviour

The first stage of the RTM process concerns the preforming of the part. During the preforming of multilayered reinforcements, frictions between the plies occur. An experimental device designed to analyse the ply/ply, ply/tool and yarn/yarn frictions has been set up. Specific contact behaviour for ply/ply friction is directly related to shocks taking place between overhanging yarns of each sampl...

Impact Damage in Woven Fabric Reinforced Composites

INTRODUCTION Very often, woven fabrics are used as the reinforcement in advanced composite materials. Although the resulting inplane stiffness is lower than of their unidirectional counterparts, the excellent drapability of these materials eases the production of more general doubly curved components. In addition, the inherently low out-of-plane strength of these layered materials improves due ...

Thermomechanical Properties of Woven Fabric Composites

The in-plane thermo-elastic behaviour of woven fabric reinforced composites is analysed using a combination of published micromechanics and finite element techniques. The repetitive unit of an arbitrary woven fabric composite is divided into elements of which the thermo-elastic properties are determined using micromechanics. The properties of the repetitive unit are obtained using the finite el...

Effective Features of the Concentrated Loading Curves (Woven Fabric Objective Measurement)

This paper deals with evaluation of the mechanical properties of woven fabrics. Method of evaluation is concentrated loading system. A total of 17 pieces of woven fabric is used. The most related parts of the curve to the properties are shown and as a result, effective features are lightened up.
