Abstract

Gravity and centrifugal castings are considered the most economical and attractive processes for making functionally graded materials (FGMs). The control on property change in radial direction in aforesaid methods is mainly based on the initial concentration, viscosity, time, centrifugal force, particle size, and density difference in dispersed and dispersion medium as per Stoke's law. The modified Stoke's law in the form of HD model that takes into account the intrinsic changes in viscosity those occur during the polymerization of resins, was used for determining changes in concentration with time at different locations of test samples for SiC dispersed poly sulphide epoxy resin FGM. The experiments as well as simulation were conducted under gravity as well as centrifugal force. The simulated results are in good agreement with those ofexperiments. The process parameters, initial concentration, etc., can be selected for a desired concentration profile of FGM. POLYM. COMPOS., 2009. © 2008 Society of Plastics Engineers
