Modeling and Optimization of Thermal Transfer and Mechanical Properties of Bio-composite Using Response Surface Methodology

In recent years, scientists have begun to search for more sustainable biomaterials.Although many studies have been conducted on different fiber-reinforced composites, much remains to be done.Using environmentally friendly composite materials for building insulation is a practical solution to reduce energy consumption.In this study, an advanced statistical approach using JMP software was adopted to manage a complex problem involving multiple parameters.This method was applied to optimize the thermal insulation characteristics of a bio-composite.By following a precisely designed experimental program.the study focuses on analyzing the impact of varying concentrations of date palm fibers (DPF) on the thermal properties of the material.The tested samples contained between 0% and 30% DPF. with a fiber length set at 7 mm.The findings of this study clearly illustrate that the thermal conductivity of the biocomposite decreases with an increase in the percentage of DPF.This phenomenon occurs because the incorporation of fibers into the composite enhances the porosity within the matrix.consequently, reducing its density.Thus.these results underscore the advantageous effect of DPF on the insulation properties of the material.
