Determination of Mechanical Properties on Co-cured Glass Powder Reinforced Composites
Main Article Content
Abstract
Co-cure adhesive joints are gaining popularity as a practical alternative to mechanical fastenings across diverse industries such as automotive, marine and aerospace. These industries require effective techniques for joining two surfaces in structural applications. The current focus of research lies in understanding the impact of water absorption on Co-Cured Glass Fiber Reinforced Composites (CCGFRP). To this end, composites were prepared using the hand layup method, incorporating varying weight percentages of Glass Powder (GP) ranging from 0.5 to 2. The prepared composites were then immersed in distilled water at 24°C for two hours, adhering to ASTM D750 standards. Tensile, flexural and impact tests were conducted to evaluate the mechanical properties of the water-absorbed composites. The results indicated that the inclusion of 1 wt.% GP significantly enhanced the tensile and flexural properties of CCGFRP, resulting in an impressive increase of 51.09% (357.95 MPa) and 106.89% (450 MPa) respectively. Additionally, the composite containing 0.5% wt. GP exhibited the highest impact strength compared to the other composites.
