Composite materials are finding increasing application in mechanical systems because of their desirable physical characteristics compared with metals; for example, high strengthand stiffness-to-weight ratios, and the potential for constructing complex shapes without joints or extensive machining. In addition, the dynamic behaviour of composite structures can be manipulated by judicious selectio...
Two themes form the basis of this study on fibre reinforced laminated composites: namely 'thermal residual stress' and 'transverse cracking'. Thermal residual stresses are inherent to any composite structure and are internal stress within the structure that form during manufacture. Their formation arises from the difference in coefficient of thermal expansion of the fibre and the matrix. These ...
The distinguishing characteristics of carbon fibre reinforced laminates, like low weight, high strength or stiffness, had resulted in an increase of their use during the last decades. Although parts are normally produced to “near-net” shape, machining operations like drilling are still needed. In result of composites non-homogeneity, this operation can lead to delamination, considered the most ...
The introduction of carbon-fibre reinforced plastics in load bearing automotive structures provides a great potential to reduce vehicle weight and fuel consumption. To enable the manufacture and assembly of composite structural parts, reliable and cost-effective joining technologies must be developed. This thesis addresses several aspects of joining and load introduction in carbon-fibre reinfor...
Helicoidal fibre structures are widely observed in natural materials. In this paper, an integrated experimental and analytical approach was used to investigate the compressive resistance of helicoidal fibre structures. First, helicoidal fibre-reinforced composites were created using three-dimensionally printed helicoids and polymeric matrices, including plain, ring-reinforced and helix-reinforc...
Structure– phenomenological hereditary model for prediction of viscoelastic properties of layered polymer composites based on hereditary mechanics and theory of laminated plates relationships was elaborated. Interrelated creep and relaxation constitutive equations of layered composite was derived on the basis of algebra of resolvent operators and matrix algorithms. On example of cross-ply carbo...
Poor fire resistance of fibre-reinforced polymer (FRP) restricts its further application in construction structures. In this paper, a novel fibre-reinforced cementitious matrix confined concrete column (FRCMCC) using fireproof grout as the fibre matrix was developed, and experiments were conducted to establish its performance and analyse the mechanical properties under axial compression. The te...
