For hybrid composites, the Young’s modulus was also predicted by the rule of hybrid mixtures (RoHM) [1 4]. aforementioned models and found that LAA is suitable for predicting the elastic modulus of SFRP composites. Carbon fiber is a high-strength and high-elastic modulus material, yet its specific gravity is only one-fourth that of iron. Specific modulus is defined as the ratio of modulus of elasticity to the specific gravity. Though glass fibers were used initially for the fabrication of composite structures for satellites, the most widely used fiber in recent years is carbon fiber due to its high modulus, near zero CTE for the composite in fiber direction and processability [52].
