The presented research involves two types of Smart adaptive composite beams (SAC). The study was conducted on smart composite beams composed of LY5210 and EPOLAM 2063 resin systems respectively. The fabrication of composite beams involved embedding SMA wires in between layers of 0/90 woven glass fibre in the respective resin systems, followed by suitable curing and post curing cycles. Suitable mould was designed and manufactured to facilitate the required pre-straining of SMA wires. Both static and dynamic tests were done on the SAC specimens to study the behaviour of these SACs. Static and free vibration analyses were carried out using MSC Nastran and Hypermesh. There has been good agreement between the results of finite element analysis and the experimental results.
