EFFECT OF POISSON'S RATIO OF AN ELASTIC FILLER ON FORCE TRANSFER BETWEEN EMBEDDED MICROFIBERS

Abstract

The nature of the stress field which develops in a composite material formed of microfibers embedded in a filler substance was investigated. A mathematical analysis is carried out for a representative layer of filler substance contained between two rows of microfibers. The case is considered when one row consists of an infinitely long microfiber, while the second row is composed of two semi-finite microfibers. An exact solution, based on the two-dimensional theory of elasticity, is obtained for the stress field which is activated by giving the two semiinfinite microflakes a tangential displacement of separation. An unexpected peculiar influence of Poisson's ratio of the filler is found which leads to a practical recommendation to avoid fillers with a high value of Poisson's ratio. (Author)
