Summary on Grant Application Form |
|
The need for conformable damping coatings arises from the increasing requirements of reduced weight and cost, and improved life cycle behaviour of components exposed to vibration and noise environments such as aerospace and automotive components and increasingly, the domestic products such as washing machines etc. This multidisciplinary basic research project offers a new approach to the long-standing problem of how to efficiently increase the damping in complex structural components using coating technologies. By combining the expertise of four top research laboratories, three new and novel polymeric materials (Liquid Crystal Rubbers, Sol Gels and Block Copolymers) will be researched to model and optimise their cyclic energy dissipation properties when used as thin conformable coatings. Numerical and molecular modelling methods will be used together with the measured material properties and vibration tests to establish optimum damping coatings that will have wide-ranging applications.The Cambridge-based Liquid Crystal Rubber research will concentrate on maximising the high-frequency losses in the plateau-stress region (soft elasticity), primarily by using the low-molar weight plasticisers, and examining the non-equilibrium high-frequency mechanical behaviour, looking for novel stress-strain regimes and enhancing the damping.
