纤维尺寸对纤维悬浮液屈服应力的影响
Influence of Fiber Size on the Yield Stress of the Fiber Suspension
摘要
Abstract
The yield stresses of the suspensions containing different size nylon fibers were measured by the rheometer with the propeller-type rotor at the same fiber volume fraction and crowding number.The yield stresses of the suspensions containing different mixing ratios of two kinds of nylon fiber were also studied.The results showed that the suspension containing the fiber with larger aspect ratio showed higher yield stress at the same volume fraction.But there was no regular relationship between the aspect ratio and the coefficients of power-law equation of the yield stress and the volume fraction.The yield stress could not be expressed by the function only with the crowding number but was inversely proportional to the aspect ratio.So at the same crowding number,the suspension containing the fiber with lower aspect ratio showed higher yield stress.The yield stress of the mixing suspension of two kinds of nylon fiber decreased linearly along with decreasing of the volume fraction of the fiber with lager aspect ratio.关键词
