This article explains to study the feasibility of natural fiber (date palm frond and coir fibers from Oman) reinforced polymer composite laminates processed using the hand lay method. Untreated and alkali-treated fiber composite laminate specimens of longitudinal and transverse direction fibers were subjected to various mechanical property tests (such as tensile, flexural, compression, shear, and hardness). Results show that the required polymer composite is ecofriendly, has no harm by natural fiber composite, and enhances mechanical strength and low density with specific strength. Hence, it is suitable for industrial and structural applications due to its improved mechanical properties.
