Modelling the Distortions of Skewed Woven Fabric Reinforced Composites
نویسنده
چکیده
INTRODUCTION Woven textile structures are often used as reinforcements in composite materials. Their ease of handling, low fabrication cost, good stability, balanced properties, and excellent formability make the use of Woven Fabrics (WF) very attractive for structural applications in, for example, the automotive and aerospace industry. However, due to the process of draping the fibre orientation varies over the product. During production these inhomogeneous properties will lead to internal stresses, which lead to product distortions such as shrinkage and warpage. In order to predict these distortions, the thermo-elastic properties of the composite must be known.

Modelling the Thermo - Elastic Properties of Skewed Woven Fabric Reinforced Composites
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...

متن کاملThe Effect of Surface treatment on the Properties of Woven Banana Fabric based Unsaturated Polyester Resin Composites
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...
