Yazid Yahya, supervisor Mechanical engineering Also available in printed version The search for the solutions to mend the unsatisfactory performance of conventional materials are inevitable, especially when it comes to materials which cannot respond to surrounding stimuli at a certain engineering application. Thus, the materials such as adaptive or smart composites are sought out as a potential alternative where it can be applied to some engineering application that simply cannot be achieved with the existing conventional materials. The primary aim of this research project is to investigate the mechanical performance of shape memory alloy embedded into basalt/epoxy fibre reinforced polymer (BFRP) composite. The pull-out test was conducted in accordance to the method from the past experiments. There were three different parameters used for the pull-out test: untreated SMA wire, acetone-coated SMA wire and roughened SMA wire. The purpose of the pull-out test being conducted is to investigate the interfacial behaviour between the wires� surface and the epoxy matrix polymer. As to determine the flexural properties of the BFRP composite embedded with SMA wires, a three-point bending test is conducted. The test was carried out according to the standard ASTM D790. The parameters are dictated by the number of SMA wires embedded into the composite, which are 0, 1, 2, and 3 number of SMA wires; and the difference between the activated and non-activated SMA wires via Joule heating method. The results from the pull-out test shows an improvement in the interfacial bonding strength by 62.14% for roughened surface SMA and 26.38% for acetone-coated SMA. From the flexural test, the effect of activation of 1, 2 and 3 SMA wires within the composite beams lead to a slight improvement of about 10.98%, 3.08% and 1.46% respectively. The effect of embedding 1, 2 and 3 SMA into the composite beam has greatly enhanced the material stiffness of about 55.74%, 81.36% and 87.6% respectively. It was found that these improvements in the properties cannot last long at high temperature owing to degradation of interfacial strength between SMA and the composite due to recovery stress generated upon activation. After obtaining all the results, the failure modes of the specimens were analysed through Scanning Electron Microscopy (SEM). It is conducted to provide a much more detailed analysis on the internal behaviour of the materials tested, whilst giving a more solid prove to the results of the failure modes. fahmimoksen UTM 69 p.
