Effect of thermal treatment on mechanical properties and thermogravimetric analysis of laminate composite jute/epoxy

The search for new materials is the primary objective of industrialists from the point of view of technological, economic and ecological interest. To this end, several studies have been carried out on naturally reinforced composite materials. In this context, the use of natural jute fiber as a reinforcement and a epoxy resin is adopted in the study that we have carried out in this travel. The aim of this research is to elaborate a composite laminate based on epoxy thermosetting matrix and jute fibres. The laminate composite were fabricated using hand lay-up process and to study the effect of temperature at different thermal cycles from ambient to 100 degrees C passing through the following thermal cycles 40 degrees C and 80 degrees C for 1 h on the mechanical and thermal properties, tensile, hardness and thermogravimetric analysic tests will be performed on 3 layers of jute. All specimens are prepared according to ASTM D3039. Microscopic tests (SEM) are carried out to analyze the interfacial characteristics of the internal structure of the composites. The findings revealed that at 80 degrees C treatment improves the properties of the jute epoxy composite (JEC) and also the adhesion of the fibers in the epoxy matrix. These changes were attributed to a modification of the adhesion forces at the fiber/matrix interface. Copyright (C) 2022 Elsevier Ltd. All rights reserved.
