The dynamics and scientific visualization for the electrophoretic deposition processing of suspended colloidal particles onto a reinforcement fiber.

摘要

To meet the demands for new, innovative and more efficient manufacturing techniques of matrix composite materials, a method based on the ideas of colloid science has been introduced. The method relies on maximizing the electrophoretic deposition of suspended colloidal matrix particles onto a reinforcement fiber. A numerical algorithm has been developed to simulate the many body problem for the colloidal system. The algorithm uses numerical integration to solve the dynamical equations of motion. Motion of the particles are due to London-van der Waal forces, Coulombic forces, gravitational forces and Stoke's drag.;Visualization of the algorithm in two dimensions has been attempted on a personal computer. A menu user interface allows flexibility and efficiency for modifying the initial condition parameters such that the optimal initial condition parameters that maximize the matrix-collector deposition may be determined.;The colloidal suspension simulator algorithm was intended to be tested with parameters for Fe-40Al matrix particles using an Al
