    • The adherence of an individual fibre embedded in a polymer matrix is determined by a drawing experiment in which the fibre is drawn out of the polymer matrix and simultaneously the pertaining force-distance diagram is registered. To this end a test sample consisting of the polymer matrix with the individual fibre embedded therein is manufactured by melting down a quantity of polymer present in granular or powder form on an object holder, the individual fibre is dipped into the molten polymer mass and the polymer mass is subsequently cooled down below the melting point. Subsequently the object holder with the test sample adhering thereto is brought into a force-distance measuring device, and the free end of the fibre is fixed to a chucking device moveable in the direction of the fibre. In the drawing experiment, the drawing force acting on the fibre is converted into corresponding electrical signals by the force transducer, and evaluated, and simultaneously the distance covered by the chucking device is converted into corresponding electrical signals by the distance transducer, and evaluated.
    • 嵌入聚合物基质中的单独纤维的粘附性通过拉伸实验来确定,其中将纤维从聚合物基质中拉出,同时注册相关的力距离图。 为此,由聚合物基质和嵌入其中的单独纤维组成的测试样品是通过在物体保持器上熔化颗粒或粉末形式存在的一定量聚合物来制造的,将单个纤维浸入熔融聚合物物质中,并且聚合物 随后将质量冷却至低于熔点。 随后将附着有测试样品的物体夹持器插入力距离测量装置中,并且将纤维的自由端固定到沿纤维的方向移动的夹紧装置。 在绘图实验中,通过力传感器将作用在纤维上的拉力转换为相应的电信号,并进行评估,并同时将夹持装置覆盖的距离由距离传感器转换为相应的电信号,并进行评估。
