Abstract
This study analyzes the tensile strength of a sandwich-structured hybrid composite incorporating apus bamboo fiber as the core and WR400 glass fiber as the outer skin layers with an epoxy resin matrix. Natural fiber composites offer sustainable material solutions; however, they possess limitations in mechanical properties, prompting hybridization with glass fiber to enhance their structural performance. Specimens were fabricated using the manual hand lay-up method at fiber volume fraction variations of 30%, 40%, and 50%, with an alkali treatment (5% NaOH solution) applied to the apus bamboo fibers to improve interfacial bonding with the matrix. Tensile testing conducted in accordance with the ASTM D3039 standard revealed that the tensile strength is directly proportional to the increase in fiber volume fraction, where the highest average tensile strength was achieved at the 50% volume fraction (182.03 MPa), followed by the 40% fraction (150.18 MPa) and the 30% fraction (96.97 MPa). This hybrid configuration demonstrates structural capabilities far superior to pure bamboo composites, highlighting its strong potential as a sustainable material alternative for medium-load engineering applications. Nevertheless, the increase in the coefficient of variation (CV)—from 7.03% (at 30% volume fraction), 9.52% (at 40% volume fraction), to 11.96% (at 50% volume fraction)—indicates higher data scatter at increased fiber loadings, signifying the necessity for future fabrication process optimization to minimize the presence of void defects.
