Theoretical Analysis of Conductivity for Composite Bipolar Plate

چکیده
Conductive composite bipolar plate is made of composite materials filled with high content conductive filler. The conductivity of this bipolar plate is influenced by many factors. It is difficult to use a formula to accurately calculate its conductivity, and current models have certain defaults. In this paper, in view of the contact resistance, a model is established and the conductivity formula has been educed. The conductivity formula reveals some factors that influence the conductivity, especially the particle size and pressure. Several ways to improve the conductivity of the composite material are discussed.

متن کاملAn Introduction to a New Criterion Proposed for Stopping GA Optimization Process of a Laminated Composite Plate
Several traditional stopping criteria in Genetic Algorithms (GAs) are applied to the optimization process of a typical laminated composite plate. The results show that neither of the criteria of the type of statistical parameters, nor those of the kinds of theoretical models performs satisfactorily in determining the interruption point for the GA process. Here, considering the configuration of ...
متن کاملVibration analysis of a rectangular composite plate in contact with fluid
In this paper, modal analysis of the fluid-structure interaction has been investigated. Using classical laminated plate theory, a closed form solution for natural frequencies of FSI is extracted. For fluid, homogenous, inviscid and irrotational fluid flow is assumed. Then, a combined governing equation for the plate-fluid system is derived. In order to validate the equations and results, they a...
