摘要：

An experimental study is made of the flow of a continuous fibre-reinforced laminate subject to plane shear. An apparatus has been constructed in which a plate can be withdrawn from a composite comprising of layers of aligned fibres set within a resin. Experiments are performed on a 'model' composite consisting of nylon fibres in a Newtonian matrix. Measurements of the longitudinal and transverse viscosities of single layers for different fibre concentrations have been made and compared with those obtained from a linear oscillator. During the experiments considerable structure reorganization and the formation of resin layers were detected. The origins of these phenomena and their effect on the results obtained are discussed.
