The focus of this paper is the realization and verification of a modified fiber bundle pull-out test setup to estimate the adhesion properties between threads and elastic matrix materials with a more realistic failure mode than single fiber debond techniques. This testing device including a modified specimen holder provides the basis for an adequate estimation of the interlaminar adhesion of fiber bundles including the opportunity of a faster, easier, and more economic handling compared to single fiber tests. The verification was done with the single-fiber and microbond test. Overall, the modified test setup showed the typical pull-out behavior, and the relative comparability between different test scales is given.
本文的重点是实现并验证一种改进的纤维束拔出试验装置，以评估线与弹性基体材料之间的粘附性能，其失效模式比单纤维脱粘技术更符合实际情况。这种包括改进试样夹具的测试装置为充分评估纤维束的层间粘附力提供了基础，与单纤维测试相比，它具有操作更快、更简便且更经济的优势。通过单纤维和微粘结试验进行了验证。总体而言，改进后的测试装置呈现出典型的拔出行为，并且给出了不同测试尺度之间的相对可比性。
