Abstract

[Abstract]: This research project aims to examine the manner in which aluminium particles, reinforce a polymer matrix in respect to impact energy absorption and long term static loaded specimen. In order to observe the behaviour of aluminium particulate two tests were conducted, impact tests and creep tests. The results obtained from these tests were compared with neat resin specimens to evaluate the degree to which the aluminium particles affect the polymer matrix. Vinyl ester serve as the polymer matrix to which aluminium particle were added in different percentage amounts in accordance to the overall mass of resin used. Methyl ethyl ketone peroxide was the catalyst chosen to assist in the curing process. These two chemical agents were chosen due to their low cost and its mechanical properties. Extensive testing conducted in previous studies has shown that these two chemicals allow for the best composite structure. Two separate standards were used for the two tests, each standard referred were used for the preparation of the samples and the testing procedures that were followed. For impact tests ISO 179-2 was used and for creep tests ASTM 1337-96. The impact test proved that the addition of aluminium particle allowed for the absorption of a larger amount of impact energy in comparison to the neat resin specimen. To analyse the impact test results further, Charpy impact strength was calculated, which demonstrated the ability of the aluminium modified polymer matrix to absorb more energy per square metre than neat resin. A creep testing device was designed and made to carry out the tests. However, creep tests proved to be less successful as tests did not provided suitable creep results. Only two specimens were tested for the creep tests as time constraints did not allow for long term tests to be conducted. Finally, future work main will consist of modification to the design creep testing device to obtain results which would represent the creep stages better.
