ABSTRACT In the present scenario, it has been witnessed that the use of natural fibers has been employed for the wide variety of applications because of its innumerable advantages as compared to the conventional materials. In this thesis, pineapple leaf fiber - (PALF) has been employed along with the PLA for enhancing the mechanical properties of the composites. Honeycomb sandwich composites are the special type of composites materials which are fabricated by bonding core structure of the honeycomb sandwiches with the thin plate skins at the top and bottom. These are the special type of hybrid composites where the main concentration is to have a sustained mechanical property with reduced overall weight. This reduced weight makes it ideal for the wide range of applications like automobile, aerospace, constructions and many more. Hexagonal honeycomb structures possess high flexural rigidity, bending strength and compression. In the present work, the Additive Manufacturing technique has been utilized for the fabrication of honeycomb core structure. Manual hand lay up method is used for fabricating the composite.
