Effect of study of composite materials under high-velocity impact

<ns3:p>The research investigates the design, fabrication, and experimental and theoretical testing of a hybrid composite material. The purpose of the research is to find the design and precise calibration of a custom-made projectile launcher, which ensures consistency in the impact tests.It can achieve these aims by calibration according to air pressure variation, checking the consistency in the velocity of the projectile, hence proving the reliability of the device for impact resistance measurements.Test results indicated that an increase in glass fibre percentage significantly improved the values of tensile strength and shock resistance for the tested samples, with the best performance attained for specimens containing a 60% fibre content. The addition of aluminium powder exhibited a moderate improvement in the material characteristics at impact absorption. This study proposed that the addition of carbon fibres or replacing aluminium powder with copper powder could further increase the resistance to impact.It is suggested to carry out the study, which provides useful input into the development and optimisation of the hybrid composite materials, plus forms an extremely solid basis for studies that could be dedicated later to further improvement of the material performance in view of commercial applications. By combining practical testing with theoretical research using SolidWorks and ANSYS, it has been proven that hybrid materials work well in any application requiring high tensile strength and impact resistance.The effect of aluminium powder exhibited a moderate improvement of the material characteristics at impact absorption. It has again been proposed that the addition of carbon fibres or replacing aluminium powder with copper powder will further increase the resistance to impact. The results showed a significant increase in tensile strength and shock resistance, especially for samples affected by the glass fibre content, which improved the shock resistance grade of the material.</ns3:p>
