Abstract

This research examines the strength of the UPRs-Cantula composite with the
addition of filler microcrystalline cellulose (MCC). Composites were created
with a volume fraction of 30% Vf and a 45° angle. This angle variation received
the same treatment as the others, including untreated, alkaline, and fumigation.
The treatment time for alkali treatment was 6 hours, while the treatment time
for fumigation was 10 hours. The strength of each angle variation was
determined, as well as its treatment of tensile strength, modulus of elasticity,
and Poisson's ratio UPRs-cantula composites. According to the results, the
alkali treatment produced the highest tensile strength and elastic modulus
values. The highest Poisson ratio value was discovered without treatment at a
45°. The alkaline treatment yielded the highest tensile strength and modulus of
elasticity test results. The pullout fiber fracture dominated the untreated
composite fracture, whereas the fiber breakage fracture dominated the alkaline
treatment.
