Educated to PhD level with 5 years of research experience in the field of advanced composite materials. Possessing sound knowledge and experience in accelerated weathering, mechanical testing and characterisation of carbon fibre composites.

As well as excellent experience in nano-composites production and characterisation. Considerable experience in teaching and student supervision.

The main focus of my research is on the long-term lifetime behaviour of polymers composites. I am currently working on industrial research projects studying moisture absorption and its effect on mechanical and physical properties of carbon fibre reinforced epoxy and carbon fibre reinforced phenolic composites. Mechanical testes include tensile, compression, shear, strain energy release and interlaminar shear. A variety of analysis techniques (DSC, TGA, FTIR, DMA) for investigation of physical properties.

Teaching

  • EG-281 Polymers: Structure and Processing

    The module will explore the link between processing methods, microstructure and mechanical properties of polymers and polymer-based composites which will give a good understanding and knowledge about the effects they have on the behaviour of these materials.

  • EG-M73 Composite Materials

    A detailed coverage of current polymer, metal and ceramic matrix composite systems for applications in gas turbines focusing on their performance envelope, advantages and limitations. The units will cover the following: The components and their attributes - an overview (reinforcements, matrices and interfaces), Properties of the matrix materials (Thermosets/thermoplastics, metals, ceramics, structure and mechanical behaviour), Properties of fibres and particles (Glass fibres, organic fibres, carbon fibres, ceramic particles and fibres; processing, structure, mechanical response), Composite manufacture (Piles, weaves, preforms, moulding pultrusion, filament winding, powder metallurgy, casting spraying), Mechanics of reinforcement (Rule of mixtures, anisotropy, laminate structures, stress- strain response), Basic stress analysis and failure mechanisms (Stress transfer and partitioning, multiple failure events, progression of fracture, toughness), Fatigue design considerations (Damage progression, reinforcement effects); Calculations.

  • EGA301 Composite Materials

    This module provides a detailed coverage of the structure, properties, processing and applications of composite materials. It focuses particularly on their engineering use in applications such as the automotive, marine and aerospace sectors. The module covers polymer, ceramic and metal matrix composites.

  • EGA307 Polymers: Structure and Processing

    The main objective of this course is to ensure familiarisation with the methods available for fabrication of polymer and polymer-composite products, leading to an appreciation of structure/processing relationships. As a background to this, certain underlying aspects of additive technology and rheology are discussed. In addition, students will be made aware of the principal factors governing material and process selection with polymers. This will be illustrated through the use of several case-study examples on materials selection and design with polymers.

  • EGF309 Advanced Materials

    This module will cover the detailed mechanical behaviour of both metallic alloys and fibre composites. It will start with a recap of tensile failure mechanisms, but extend to compression and shear failures. Fracture mechanics will then be introduced as applied to metallic materials and be extended to damage accumulation methods for composite materials. Creep, fatigue and impact will be covered as will the effects of elevated temperature and external environmental conditions.
