From the Preface
The function of this publication is to offer inside of a unmarried quantity, precise details about the technological know-how, processing, functions, characterization and homes of composite fabrics strengthened with brief fibres which were orientated in a well-liked path through flows coming up in the course of processing. This ebook is meant to be precious to . . . fabrics scientists and different experts within the box . . . and engineers, designers and manufacturers of composites strengthened with brief fibres. To our wisdom, this is often the 1st time info relating this crucial classification of engineering fabrics has been systematically offered inside of a unmarried quantity.
The goal of aligning brief fibres in a fibre-reinforced fabric is to enhance the mechanical houses of the ensuing composite. Aligning the fibres, regularly in a popular path, permits them to give a contribution up to attainable to reinforcing the fabric. In a few cases, the mechanical houses of those aligned, short-fibre composites can technique these of continuous-fibre composites, with the further benefit of low construction charges and larger ease of creation.
The publication covers conception, processing, characterization and houses. extra particularly, the subjects thought of . . . contain fibre alignment and fabric rheology; approaches which can produce fibre alignment in polymeric, liquid crystal polymeric and metal composites; fabrics characterization and mechanical houses; and modelling of tactics and fabric homes

Greater thermal conductivity reduces heating 26 Flow-induced alignment in composite materials and cooling times, while a reduction in thermal expansion enhances the dimensional stability of the final product. Short-fiber compounds are typically used when extrusion is employed. Extruded structures exhibit significant fiber orientation which results from the shear deformation near the surface and the elongation at the center of the extrudate. Die design can be modified to tailor the orientation of the fibers to specific applications.
