Abstract
In this work, experiments were carried out to develop the glass fiber reinforced composites using the hand layup method and analyze the mechanical properties of the GFRP hybrid composites. The ultimate Tensile strength (UTS) using rice as a filler (GFRPC/R) was 3.04% and 12.89% higher than coir and wheat as filler, respectively. The hybrid composite using coir as a filler (GFRPC/C) revealed 12.54% greater flexural strength, and the hybrid composite using wheat as a filler (GFRPC/W) revealed 14.95% inferior flexural strength than the plain GFRP composite. Hybrid GFRPC/C composite showed the highest impact strength of 278.93 J/mm2, and GFRP composite showed the most minor impact strength of 234.37 J/mm2. Hybrid GFRPC/W showed the most minor impact strength of 245.53 J/mm2. Hybrid GFRPC/C composite showed 15.95% higher impact strength than plain GFRP composite. Hybrid GFRPC/R showed the highest hardness of 41.375 BHK, comparable with the GFRP composite. Hybrid GFRPC/W showed the lowest impact strength of 33.25 BHK. Hybrid GFRPC/R showed 13.23% and 19.63% higher hardness than hybrid GFRPC/C and GFRPC/W respectively.
