This study investigates the mechanical and structural properties of bamboo-glass fiber hybrid composites with
the aim of optimizing strength-to-weight performance for advanced engineering applications. Composites were
fabricated using the Vacuum-Assisted Resin Infusion (VARI) method to ensure uniform resin distribution and
reduced void content. Four configurations—bamboo (BBBB), glass (GGGG), and hybrids (BGGB, GBBG)—were
analyzed. GGGG exhibited the highest density (1.697 g/cm
3
) and tensile strength (125.86 MPa), while BBBB
demonstrated the lowest density (0.954 g/cm
3
), highlighting bamboo lightweight advantage. Hybrid composites
improved tensile strength by 24–30 % and flexural strength by 16–58 % compared to pure bamboo composites,
with BGGB achieving superior tensile performance (87.24 MPa) and GBBG excelling in flexural strength (99.16
MPa). Specific tensile strength showed BGGB as the most efficient (86.39 MPa/g/cm
3
), followed by GBBG, while
specific flexural strength revealed GGGG as the highest (108.76 MPa/g/cm
3
), with GBBG offering a balanced
performance (97.4 MPa/g/cm
3
). The stacking sequence significantly influenced the performance, with BGGB
optimizing the tensile stress distribution and GBBG enhancing the load transfer through glass fibers in the outer
layers. Microstructural and FTIR analyses revealed that the hydrophilic and porous nature of bamboo weakened
interfacial bonding, while glass fibers formed strong chemical bonds, improving rigidity and load transfer. These
findings highlight the potential of bamboo-glass hybrid composites as sustainable, lightweight, and high-
performance materials suitable for applications in sports equipment, automotive components, and other
advanced engineering applications |
