摘要:	本文建議用一種二維的複合材料短纖維模型,來模擬單向的複合材料纖維材分布。用高等的剪力分析導出微分方程式,解得沿著短纖維的應力分布狀況。其特色是除了基礎材料和纖維假設為完美結合之外,短纖維端點間的基材亦承受軸向負荷,就如纖維材的一部分。更進而可解得平均的應力分布,其公式可應用在預測內部材料的阻尼值。 The present paper proposes a three-fiber model represents a two dimensional aligned short-fiber arrangement in the matrix material. An advanced shear-lag analysis is used and modified to develop analytical relations for the stresses along the short-fiber length. This analysis assumes perfect bonding between the fiber and the matrix materials, and allows for the matrix material to partially sustain axial loads. The average stress in a representative fiber length can be obtained through averaging formula.
