ステンレス繊維充てん変性ポリフェニレンエーテルのクリープコンプライアンスに及ぼす繊維含有率の影響

抄録

Polymer matrix composites have sometimes been used for shielding electro magnetic interference (EMI). In order to make clarify the effects of the fiber volume fraction of the composites on creep phenomenon, the creep behavior during 3-point bending creep tests was investigated at various constant temperatures. The material used had stainless steel fiber conductive fillers and a metamorphic poly-phenylene ether matrix. Three fiber volume fractions were 0.73, 1.52 and 2.39%. The master curves of creep compliance were obtained by applying the Arrhenius reciprocation laws of time and temperature for all materials. The shapes of the 3 master curves were found to be the same, being shifted on the time axis and on the creep compliance axis. Therefore it was concluded that creep behavior of the materials depended mainly on the viscoelastic property of the matrix resin and also depended not only on time and temperature, but also on fiber volume fraction.
