An Introduction to Composite Materials

Abstract

This edition has been greatly enlarged and updated to provide both scientists and engineers with a clear and comprehensive understanding of composite materials. In describing both theoretical and practical aspects of their production, properties and usage, the book crosses the borders of many disciplines. Topics covered include: fibres, matrices, laminates and interfaces; elastic deformation, stress and strain, strength, fatigue crack propagation and creep resistance; toughness and thermal properties; fatigue and deterioration under environmental conditions; fabrication and applications. Coverage has been increased to include polymeric, metallic and ceramic matrices and reinforcement in the form of long fibres, short fibres and particles. Designed primarily as a teaching text for final-year undergraduates in materials science and engineering, this book will also interest undergraduates and postgraduates in chemistry, physics, and mechanical engineering. In addition, it will be an excellent source book for academic and technological researchers on materials.

Multifunctional Structural Supercapacitor Composites Based on Carbon Aerogel Modified High Performance Carbon Fiber Fabric

“…27 However, a much more critical, and demanding question is whether the matrix- Figure S3a, b); similar failure mechanisms for woven carbon fibre/polymer structural composites are reported in the literature. 41 As summarised in Table 3, the shear modulus of the DGEBA-based composites increased by around 15% due to the stiffening effect of the CAG-modification, whilst the shear strength remained constant.…”

“…However, in order to utilise the excellent mechanical properties of carbon fibres in a multifunctional composite structure, a high loading fraction of carbon fibres is needed; around 55-60 vol.% is typical for woven structural composites. 27 For this reason, an alternative infusion route was developed, to provide thin, uniform laminates of CAG-modified carbon fibre fabrics. Vacuum-assisted infusion methods have been widely used for resin infusion in traditional fibre-reinforced composite manufacturing, 19 highlighting their suitability for large-scale manufacturing.…”

Improved Adhesive Strength and Toughness of Polyvinyl Acetate Glue on Addition of Small Quantities of Graphene

“…Under such circumstances, material fracture generally involves failure of the polymer graphene interface rather than breaking of the flakes. 5,36,48 Under these circumstances, we can write…”

Estimation of the reinforcement factor ξ for calculating the transverse stiffness E2 with the Halpin–Tsai equations using the finite element method

“…The H-T equations can be found in many books on mechanical behaviour of composite materials [1][2][3][4]. The H-T equation for the transverse modulus…”

“…Analogous equations are formulated for G 12 and ν 23 [1][2][3][4]. For the longitudinal modulus E 1 and ν 12 the well-known rule of mixtures holds [1].…”
