Abstract: |
The polymer matrix composites with natural fibers have been in use with various industries such as automotive, aerospace, construction and others for different applications. In pursuit to gaining popularity, a natural fiber reinforced polymer composite (NFRPC) with polyester as matrix and jute fabric as a reinforcement along with alumina as particulate material has been synthesized to investigate its mechanical properties. In the present study, the bending behaviour of the composite material has been investigated to know the effectiveness under different load conditions. The study evaluates the effectiveness of natural fiber materials as reinforcement, as they are available in abundant, biodegradable and cost effective. The specimens are prepared using three laminates of size 310 x 310 x 4 mm, produced by hand layup process. Three specific compositions A, B and C with 18%, 22% and 26% by weight of jute fabric along with 8% of alumina and rest of the weight fraction constituted of polyester resin respectively were used to prepare the laminates. The water jet cutting process was employed to cut the specimens as per the ASTM standard dimensions from the laminates. There were 3 specimens for each of the compositions prepared. The specimens were subjected to mechanical characterization tests of tension and compression using Universal Testing Machine (UTM). The specimens exhibited reduced bending strength as the increase in weight percentage of jute fabric and thus denotes good bending strength at 18% and drastic reduction at 24% and 26% of jute fabric reinforcements. |
