Abstract:
Currently, there is an increasing trend of utilizing composite materials in various sectors
of engineering and technology, particularly aerospace and industrial application, for
their exceptional mechanical and thermal properties, lightweight, and lower cost. In a
composite, the constituent materials collectively work to create a new substance whose
properties are superior to those of the original components. A number of factors affect
the properties of the composite material. This paper addresses the effects of the stacking
sequence on the tensile and flexural behavior of Jute/Carbon Epoxy hybrid composites.
Five specimens of unidirectional Jute/Carbon fiber reinforced composite were fabricated
for each of the five stacking sequences of a test to investigate the mechanical properties
of the composite. The distinct stacking sequences consisted of equal quantity of fiber
components. Specimens were fabricated using vacuum assisted resin infusion process
under the ASTM guidelines. Experiment results revealed that similar amount of load or
force generated varying responses on specimens with varying stack up sequences.
Further, identical stacking sequences had different effects on different tests.
Sandwiching four Carbon plies between six Jute plies proved beneficial for the
composite’s tensile behavior, but derogatory for its flexural one. The experimental
results were validated using ACP in ANSYS by recreating the composite laminate,
taking into account the distinct stacking sequences and exact experimental conditions.
The FE Analysis of the tensile and flexural tests consisted outcomes similar to those of
the experimental results, with acceptable errors ranging from 3%-5%.
