Summary on Grant Application Form |
|
Composites are routinely used at low temperatures in the aircraft, space and superconducting industries. A particuliar application of composites fo at low temperatures is of superconducting magnets which have been develped for a range of products such as body scanners. The requirement fo high magnetic fields though is primarily being driven by research applications. The development of high magnetic fields is placing higher strains or magnet components. A better understanding of the thermal strains due to cooling of the magnet coil is therfore becoming necessary to continue tc increase the magnetic field. The complex nature of the composite that forms a magnet coil makes analytical analysis of the strains due to thermal cooling difficult and therefore there is a requirement to develop an experimental method to measure the strains in the coil. It is therfore intended to develop a Moire interferometer which will work at cryogenic temperatures. This technique gives very high strain resolution but is sensitive to therm currents. The reduction of thermal effects will be the major obstacle to overcome although specimen preparation will also present some problems, there is a requirement with Moire interferometry to attach a grid onto the specimen surface.The data obtained from testing will be used to develop analytical and numerical models of composite structures subjected to low temperatures anc to improve the design and manufacture of composites for use at low temperatures.
