遠心力を利用して成形した傾斜型金属粒子充てんエポキシ樹脂複合材料

New gradient polymer composites were fabricated from epoxy resin filled with metal particles by applying the centrifugal force. Density and electrical conductivity measurements were carried out on samples filled with nickel particles, copper particles and a mixture of both metals. Centrifugal force was applied to samples by a centrifuge machine. Volume distributions of particles were derived from density measurement of samples. The centrifugal force produced the gradient particle distributions in the samples. Particle size markedly affected particle distributions. The electrical conductivity of samples varied in the direction of centrifugal force applied to samples. An additivity law for the volume contents of particles was established for samples filled with particles of different sizes.
