Sawchuk, Mike (2008) Flexural strength SLG-reinforced phenolic composites cured in microwaves. [USQ Project]
[Abstract]: As time passes and technology gets more developed it is applied in every aspect in human life. One of the applications in which we have the most to gain is in the use of composite materials being used as engineering building materials. Currently these composites are replacing foundation building materials such as steel and wood. Since the composites are made of different materials they can possess different mechanical properties and this is the source of their popularity. One main characteristic desired from a composite is a cheap cost. Cheap efficient filler is required to make the composite more cost effective.
This study tests a composite composed of Envirospheres, phenolic resin, and a catalyst. Envirospheres are small ceramic spheres that can be used as the filler in a
composite. Envirospheres are becoming increasingly popular because of their strength and heat resistant properties. The most optimal cost savings would be if the composite can be made with as much Envirospheres as possible. Although to possess the strongest cost to strength ratio this may no be the case; therefore 8 different sample types have been produced. The samples are mixed in percentage by weight to
resin and catalyst, starting at 0% and going as high as 35% in 5% intervals. After the samples are cured and removed from the mould they are post-cured. The postcure operation is to add desired mechanical properties, like strength and possibly flexibility. After the sample is post-cured the testing is conducted using a flexural testing machine. The flexural strength, strain and young's modulus have been
calculated from the data retrieved from the test. The results are then tabulated and compared to previous testing and a confirmed optimal percentage has been presented in the final chapter.
