Abstract
Abstract Experimental and analytical solution using classical shell theory solve by Matlab software was used to found thermal stresses under thermal load for natural composite materials pipe. Two types of natural fibers (eggshell and ash of fire wood) were used as reinforcements with polyester-resin. The experimental work including the manufacturing of the test samples (eggshell/polyester and ash of fire wood/polyester) by resin casting method with 40% volume fraction. Tensile and thermo-mechanical test were performing to find the mechanical properties of the specimens The results showed that eggshell natural composite had the highest strain, stress, and good mechanical properties compared with ash of fire wood natural composite but regarding temperature withstand the ash of fire wood specimens had the highest compared with egg shell specimens.
