About the Project

In a composite ply the nature of wave propagation is closely associated with the alignment of fibres (for the unidirectional case) and warp and weft arrangements (for the woven case) among other parameters, e.g. fibre volumetric fraction, relative fibre-matrix moduli, etc. As wave propagation characteristics in a laminated composite depend on features of wave motion in a single ply which in its own right is contingent upon the degree of reflection and refraction of elastic waves from fibre-matrix interface zone the study of micromechanics of mechanism of wave propagation is essential in acquisition of understanding of related phenomena (stress wave patterns, damage and fracture, etc.). It is thus important to acquire the knowledge of the latter, as a logical antecedent, for the former to transpire. Geometric alterations may be introduced in fibres to increase fibre-matrix interface fracture energy and strength through interlocking mechanisms. Wave reflection and refraction due to impedance mismatch and curvature will also form an interesting part of the study. These will also render it possible to manipulate wave propagation as required. Thus it would be interesting to look into wave propagation in such structures from a micromechanical viewpoint.

Funding Notes

Brunel offers a number of funding options to research students that help cover the cost of their tuition fees, contribute to living expenses or both. See more information here: https://www.brunel.ac.uk/research/Research-degrees/Research-degree-funding. Recently the UK Government made available the Doctoral Student Loans of up to £25,000 for UK and EU students and there is some funding available through the Research Councils. Many of our international students benefit from funding provided by their governments or employers. Brunel alumni enjoy tuition fee discounts of 15%.)
