This paper examines the effect of changing temperature on the curved natural composite material pipe (Walnut husks powder with polyester) and curvature angle θ= 34° practically. This work involves the design and fabricates of curved pipe samples with an angle of curvature θ=34° at 50 % weight fraction. Also, tensile and thermo-mechanical test were performing to find the mechanical properties of the specimens. Experimental work included design and manufacturing test rig to simulate thermal stress. The experimental results revealed that a maximum hoop strain and longitudinal strain increased with increasing the temperature. The hoop stresses at crown and intrados positions were more than the hoop stress at extrados position by 150.762% and 138.363% respectively, and the von mises stresses at crown and intrados positions were more than the von mises stress at extrados position by 218.259% and 178.193% respectively. In the curved pipe, the hoop strains at intrados and crown positions were more than the hoop strain at extrados position by 114.583% and 60.416% respectively.
