Abstract
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.
Highlights
Composite materials are a combination of matrix and reinforcement materials in order to get the properties of combined materials
Tensile test specimens from the laminates were prepared as per the ASTM D638 standard, as shown in Tables 4 and 5 for testing the tensile properties such as tensile strength, tensile modulus, % elongation, and the failure strain of rectangular cross section of the specimen
Four to five specimens for longitudinal and transverse direction of the fibers for all composition of composites were tested at a room temperature 23°C ± 2 with a controlled room humidity
Summary
Composites are being made for several thousand years; mud brick is an example of a composite. It has good compressive strength, so it is hard to be squashed. It breaks quite when it is attempted to bend which means it has low tensile strength. Composite materials are a combination of matrix and reinforcement materials in order to get the properties of combined materials. Composites have two main materials which are reinforcement materials (discontinues) and matrix or base (continues material)
