ABSTRACT This paper examines the effect of fiber orientation [0𝑜𝐺𝐹 / 90𝑜𝐺𝐹 / 0𝑜𝐷𝑃𝐿𝐹 /0𝑜𝐷𝑃𝐿𝐹 ]𝑆 , [15𝑜𝐺𝐹 / −75𝑜𝐺𝐹 / 15𝑜𝐷𝑃𝐿𝐹 /15𝑜𝐷𝑃𝐿𝐹 ]𝑆 , [30𝑜𝐺𝐹 / −60𝑜𝐺𝐹 / 30𝑜𝐷𝑃𝐿𝐹 /30𝑜𝐷𝑃𝐿𝐹 ]𝑆 , [45𝑜𝐺𝐹 / −45𝑜𝐺𝐹 / 45𝑜𝐷𝑃𝐿𝐹 /45𝑜𝐷𝑃𝐿𝐹 ]𝑆 , [60𝑜𝐺𝐹 / −30𝑜𝐺𝐹 / 60𝑜𝐷𝑃𝐿𝐹 /60𝑜𝐷𝑃𝐿𝐹 ]𝑆 , [75𝑜𝐺𝐹 / −15𝑜𝐺𝐹 / 75𝑜𝐷𝑃𝐿𝐹 / 75𝑜𝐷𝑃𝐿𝐹 ]𝑆 and [90𝑜𝐺𝐹 / 0𝑜𝐺𝐹 / 90𝑜𝐷𝑃𝐿𝐹 /90𝑜𝐷𝑃𝐿𝐹 ]𝑆 on the tensile behavior of continuous Date Palm Leaf Fiber (DPLF) – Glass (GF) hybrid reinforced epoxy composites. Laminate with 33% volume fraction of reinforcement (12% DPLF and 21% GF) was prepare using hand layout manufacturing technique. The developed composites were characterized by tensile test and the mechanical properties such as maximum stress, Young´s modulus, energy absorption, percentage total elongation at fracture were compared with that of the theoretical values. In the case of [0𝑜𝐺𝐹 / 90𝑜𝐺𝐹 / 0𝑜𝐷𝑃𝐿𝐹 /0𝑜𝐷𝑃𝐿𝐹 ]𝑆 and [90𝑜𝐺𝐹 / 0𝑜𝐺𝐹 / 90𝑜𝐷𝑃𝐿𝐹 / 90𝑜𝐷𝑃𝐿𝐹 ]𝑆 lamina composites, longitudinal tensile strength values has been found to be closer to each other. However, for [90𝑜𝐺𝐹 / 0𝑜𝐺𝐹 / 90𝑜𝐷𝑃𝐿𝐹 /90𝑜𝐷𝑃𝐿𝐹 ]𝑆 lamina composites shown higher energy absorption. The experimental results revealed that the tensile properties strongly depend of DPLF-matrix interface and DPLF defects. The DPLF morphology, DPLF-GF/Epoxy hybrid composite fracture surfaces and sections through the coupon were examined by means of scanning electron microscopy (SEM). SEM hybrid composite morphology study indicates that debonding, matrix cracking, matrix crazing, fiber fracture, fiber splitting and fiber pull out were the major features of hybrid reinforced composites damage characteristics.
