Reflection for 24 May 2016 (Tuesday)

Today, we did Tensile Testing and Composite Material processing. Tensile testing, also known as tension testing, is a fundamental material science test in which a sample is subjected to a controlled tension until failure. In the tensile testing session, our Mentor, Mr. Ho, helped us and explained to us the steps and the reasoning behind each step. We had an opportunity to tensile different material strips, in this case, aluminium, steel and polystyrene, to their maximum until they break. A composite material is a material made from two or more materials that, when combined, produce a material with characteristics different from the individual components. The material combined together usually forms a more useful material than the original material. It has desirable properties which cannot be obtained by either of the constituent materials acting alone. We had the opportunity to create a new material that has more useful properties. 

Today, we learn about the usage of tensile testing and composite material processing. The use of tensile testing is to test the strength, stiffness and the maximum load a material can withstand. This can then help them to make a judgement on which material to use against a product. The usage of composite material processing is to allow one to create a stronger, and more useful material such to create a better product. 

I feel that these tests and process can help us in the future if we are trying to create a new material or trying to make a product and make a judgement on the type of material to use. By doing so, we can expand our range of choices and can increase the difference between each material.
