Effect of Thermal Aging on the Mechanical Properties of Hybrid Multilayer Composite with Various Core Structure
Steels well known for their sturdiness and long-term life expectancy; however, there are drawbacks such as it is expensive, corroded as exposed to air and difficult to be formed into shape. Hybrid composite fiberglass consists of the combination of matrix, reinforcement and core structure that are well known as cheap, non-corrosive and easy to fabricate with superior characteristic that attract in many applications including utility usage as replacing steel materials. Hybrid composite panels with two different cores (aluminum and plywood) are prepared by hand lay-up method and treated at various temperature 60, 90, 120, and 150 °C. Hybrid composite fiberglass with Aluminum core observed good mechanical properties compared to plywood in the properties of flexural strength, impact and moisture resistant. Flexural strength for both Plywood and Aluminum show significant p values, meanwhile p values for strain in Aluminum observed more significant compared to plywood. Both plywood and aluminum observed significant p values in moisture test and impact strength as temperature increases. However, tensile and hardness properties show lower significant p values, R and R-square value at increasing temperature.
