Method & Evidence

AimTo investigate the potential of kenaf and bamboo fibers, combined with modified soy protein isolate resin, to create engineered 'green' composite materials with enhanced mechanical properties.
MethodExperimental material development and characterization
ProcedureSoy protein isolate resin was modified by adjusting pH and plasticizer (glycerol) content, and by incorporating a cross-linking agent (Phytagel?). Kenaf fiber mats were used as the base reinforcement, with some composites also incorporating fibrillated bamboo fiber sheets. The mechanical properties (tensile strength, Young's modulus, flexural strength, chord modulus, and impact strength) of the resulting bio-composites were then tested and compared based on the resin modifications and fiber inclusions.
