Starting his career in 1957 sampling and analysing ores and minerals, Lionel Parks went on to work on asbestos and thermal insulation materials. He eventually became MD of a company developing fire protection materials which are now used worldwide.
Team MAST has been delivering the UK Ministry of Defence’s (MOD’s) low to medium maturity materials and structures research since November 2007. This article presents case studies from that work - coatings to lower solar heat absorption, self healing of fibre-reinforced polymer composites and integrated damage resistance in composite structures.
The Departments of Materials and Mechanical Engineering at Imperial College London, UK, have been awarded roughly £5.5m by the UK’s Engineering and Physical Sciences Research Council (EPSRC) to set up a national Centre for Structural Ceramics we discuss the plans.
The four main areas of activity in the field of adhesion and adhesives at the University of Surrey are outlined: structural adhesive bonding; pressure-sensitive adhesive research; the interfacial chemistry of adhesion; and smart adhesive research.
There are many advantages that polymeric adhesives can offer compared to the more traditional methods of joining, but the structure of such thermosetting adhesives also generally results in brittle materials, with a poor resistance to crack initiation and growth. The incorporation of a second phase of dispersed rubbery particles into the epoxy polymer can greatly increase toughness for applications where a very high impact resistance is required for the adhesively-bonded joint.
Materials selection can affect tennis racket and player performance. The stiffness-related vibration of the frame and shock transmission to the player are common complaints that manufacturers are addressing through applications such as piezo materials.
