Impact Behavior of Aramid Reinforced Polymer Matrix Composites Produced By Hot Press-Prepreg Method
Abstract
In this study, the production of polymer matrix composite material from prepreg with a hot press, which is a different method from the classical autoclave method, was optimized. The impact behavior of the composite materials produced was investigated. For this, 3mm thick and 90mm diameter aramid reinforced polymer matrix composite samples were produced by hot press method. Impact tests were carried out at 15, 30, 45J energy values. For the impact tests, a 10 mm radius semi-cylindrical steel tip was used. The weight of this tip is 5,045 kg. With the impact tests, the contact force time and energy time curves of the composite samples were obtained and the impact behaviors were interpreted from there. Accordingly, as the impact energy increased, there was an increase in the maximum contact forces of the composite samples and a decrease in the contact times. Considering the energy time graphs, it was determined that there was a decrease in the amount of absorbed energy of the samples as the impact velocity applied to the composite samples increased. Besides, considering the ratio of absorbed energy to applied energy, it was observed that the energy absorption ability dramatically decreased as the impact velocity increased. Finally, the densities of the composite samples produced with the hot press were determined according to the Archimedes principle.
