Strength-to-weight ratio assessment of a cotton-glass fibers hybrid composite beam

In this work, the strength-to-weight ratio on I-beam of a cotton-glass fibers hybrid composite (64% cotton fibers and 36% glass fibers) was assessed. Numerical simulations were carried out under flexural loads and a flexural test were carried out using a Shimadzu AG-X plus 100kN testing machine. The...

Sumario:In this work, the strength-to-weight ratio on I-beam of a cotton-glass fibers hybrid composite (64% cotton fibers and 36% glass fibers) was assessed. Numerical simulations were carried out under flexural loads and a flexural test were carried out using a Shimadzu AG-X plus 100kN testing machine. The results showed that it is possible to obtain an optimized geometry within the beam through the strategic removal of material zones without compromising the structural integrity. Furthermore, the flexural test on the composite beam showed a higher value in the strength/weight ratio (44) compared to the optimized 6061-T6 aluminum beam (39.65); this behavior can be explained because fiber-reinforced composites are generally less dense compared to metals, and to the distribution of cotton and glass fibers within the beam.
