“…The size-based FGMs are further classified into thin and bulk FGMs. FGMs have good applications in the field of the nuclear industry, defense, electronics and bio-medical sectors (1)(2)(3)(4). The FGMs mostly show better surface hardness and wear resistance as compared to conventional composite materials (5)(6)(7).…”

In the present work, an in-house centrifugal casting setup was developed in the laboratory. Waste natural fillers such as soap nuts seeds, Aegle marmelos, and Terminalia chebula were used for the preparation of polyester based composite by using centrifugal casting technique. The influence of filler loading (3%, 6%, 9% and 12% by weight) on the physical-mechanical behaviour of hybrid composites has been performed. The moisture absorption tests were conducted according to the ASTM D 570-98 standards. Hybrid composites with varying composition of polyester, Aegle marmelos, Terminalia chebula, and soap nut seed were fabricated. It has been observed that the maximum water absorption was in the range of 0.23% to 2.12% (weight fraction), the maximum tensile strength 47.83 MPa, hardness 71VH and impact strength 5.8 Joule for the hybrid composite material with 12 wt% Aegle marmelos, 9 wt% Terminalia chebula, 6 wt% soap nuts seed. The minimum specific wear rate (0.00196 mm 3 /Nm) was obtained for the composition of 12 wt% soap nuts seed and 3 wt% Aegle marmelos.

“…If continuous structure is preferred, then centrifugal method which is similar to the centrifugal casting was used. Centrifugal method is limited to circular shapes and type of gradient produced since the gradient is formed through the natural process (centrifugal force and density difference) [6]. Rapid prototyping technique is an additive manufacturing process which has ability to design and produce complex shapes due to the liberty provided, as parts are developed directly from CAD data.…”

Abstract-Functional Graded Materials (FGM) are innovative materials in which final properties varies gradually with dimensions. It is the recent development in traditional composite materials which retains their strengths and eliminates their weaknesses. It can be formed by varying chemical composition, microstructure or design attributes from one end to other as per requirement.. Previous investigations show that various techniques such as powder metallurgy, centrifugal method, vapor deposition techniques, solid freeform fabrication methods and friction stir processing etc. have been used to fabricate the FGM. In order to overcome the control over the composition, the present study presents a method to fabricate Functional Graded Material using Friction Stir Processing (FSP) and hole drilling electrical discharge machine (EDM). Holes are drilled on an aluminum plate and filled with Alumina nano-particles of size (<50nm) and stirred using FSP. A mathematical model for positioning of holes in order to acquire a range of maximum to minimum composition of nano particles over a given length is presented. By aligning FSP seem tool center to hole center, multi-pass FSP is carried out to understand the material flow and mixing. The hardness variation along the direction parallel to the surface and perpendicular to the surface and along the depth is measured. The mathematical model is applied to different combinations of composition ranges and is evaluated under different conditions.
