A continuum damage mechanics (CDM) meso-model was derived for both intraply and interply progressive failure behaviors of a 2D woven-fabric composite laminate under a transversely low velocity impact. An in-plane anisotropic damage constitutive model of a 2D woven composite ply was derived based on CDM within a thermodynamic framework, an elastic constitutive model with damage for the fibre dir...

Viscoelastic properties of woven composite substrates are essential to design dimensionally stable multilayer printed circuit boards. Unlike most existing numerical work which rely on simplified constitutive (elastic) and geometrical models, this study involves a fully three-dimensional viscoelastic model of a plain weave composite with accurate characterization of the woven geometry. Compariso...

Due to the presence of through-thickness reinforcement, 3D woven composites have superior fracture toughness, fatigue life, and damage tolerance compared to laminated composites. Furthermore, 3D woven composites exhibit a progressive damage behavior which is more benign than the typical catastrophic failure behavior of laminated composites. These properties lead to high specific energy absorpti...

Textile structures are engineered and fabricated to meet worldwide structural applications. Nevertheless, research varying textile structure on natural fibre as composite reinforcement was found to be very limited. Most of the research is focusing on short fibre and random discontinuous orientation of the reinforcement structure. Realizing that natural fibre (NF) composite had been widely devel...

Influence of reinforcement effect on mechanical properties of banana bio fiber polyester has been investigated. Three different type of weaving patterns such as plain, basket and twill banana fabric were used to analyze the mechanical properties of composites. Results revealed that composite with basket weaving style enhances the properties of composite material compared to other two patterns. ...

Woven cloth composite materials have been extensively used to reinforce the structures of automobiles and the airframes of aircraft. It is well-known that a woven cloth composite \ply" has the capability of tting to fairly complex geometries. Fitting here means that a ply is deformed and applied to a 3D surface in such a way that it is in contact everywhere with the surface. However, it is not ...

Woven fabrics prove to be a very convenient fibre reinforcement when prepreg layers have to be draped on to double curvature moulds. The process of draping causes the angle between the warp and weft yarns to vary over the product with this double curvature. As a result, the thermomechanical properties of the fibre reinforced composite material show a corresponding distribution. These thermo-ela...

Moiré interferometry is utilized to investigate the time–temperature-dependent deformation of a woven composite substrate used in multilayer circuit board applications. Creep tests are performed at temperatures ranging from 27 to 70◦C, and the resulting longitudinal and transverse displacement fields are measured via moiré interferometry. Measured displacement fields reveal the influence of fab...

The evolution of damage in a woven composite results from the interaction and competition among several elementary mechanisms which are greatly influenced by the microstructure. Thus, in order to develop a model as close as possible to the physics, it is necessary to observe, understand and describe each mechanism on the most appropriate scale. In this work, the construction of a woven composit...

The contemporary Formula 1 racing car makes extensive use of advanced composite materials in its construction. The design, manufacture, and ultimate performance under compression of composite suspension push-rods that typically could be used in a Grand Prix racing car are described in this present paper. An aerofoil cross section has been used based on different lay-ups of carbon/epoxy composit...
