Abstract: The ability to quantify materials hardness and thickness co relationship ensures quality assurance. There is a strong demand in quantifying composite joint on the go. Common Non destructive test methods, such as ultrasonic, radiographic inspection and acoustic resonance testing are used in the industry to quantify quality. Furthermore, these market available test devices were expensive and bulky. In this report, a previous designed device for evaluating composite joint by another FYP student was reviewed. The shortfall of the device was enhanced and further improved with a new and better design. The concept behind the new device was based on the acoustic resonance testing fundamentals. The design concept was then being evaluated and examined. The Final product was designed with the aid of “solidWork”, 3-D modeling software. The detailed drawing was then sent to an external vendor for fabrication. The student innovates through the combination of easy available component to build the device, instead of reinventing the whole thing. This report covers the review process of the previous test device through a systematic engineering approach. The student explored and evaluates the concept of the new designed device with the help of a decision matrix based on the requirement specified. The report also consists of the engineering design process, where the student did research, conceptual evaluation, feasibility assessment, embodiment design, detailed design and finally the production of the final design. Lastly, experiments were carried out to endorse the validity of the new device. The relationship based on the readings and different environment parameters were formulate through various experiments. The validity of the establishment model was backed by theoretical hypostasis and experimental data collected. Finally, with all the comprehensive assessment carried out, the new design test device was able to meet all the objective and specification stated in this project.
