Effect of thermal treatment on mechanical properties of sustainable composite : experimental and simulation study
Abstract
The aim of this work is to accurately characterize the thermomechanical behavior of jute-polyester composites. The thermal characteristics and the mechanical properties are determined over a temperature range from ambient to 100°C. The
effect of temperature on the tensile breakage of specimens was investigated in order to determine the ability of this composite
to maintain its mechanical resistance. It was observed that Young’s modulus and the tensile strength undergo an increase of
about 80% when the temperature rises from ambient temperature to 60°C and a decrease for a temperature range from 60°C
to 100°C. Numerical simulations, based on FEM analysis, provided results in good agreement with the experimental data in
terms of the stress-strain curves. These simulations were achieved using Abaqus explicit finite element code. The increase and
decrease in the mechanical properties were attributed to modification of the adhesion forces at the fiber/matrix interface
