The stickiness of prepregs (tack) is considered a decisive material property for the success of high‐quality composite manufacturing by automated lay‐up processes such as automated fiber placement (AFP) or automated tape laying (ATL). Adverse control of prepreg tack can easily result in laminate defects or machine breakdown, which are highly undesirable considering the tremendous machinery and material costs of these processes. Prepreg tack is governed by a complex interaction of adhesive and cohesive phenomena that are influenced by machine and environmental parameters of the production process as well as by intrinsic properties of the prepreg material itself. This review aims at providing a condensed insight into the current state of research on prepreg tack. Therefore, experimental studies including the discussion of utilized tack measurement methods as well as model approaches to prepreg tack are reviewed. The findings are discussed against the background of fundamental mechanisms, the strong interdependency of influencing parameters and the challenge of translating measured tack data into an enhanced AFP/ATL process stability by process adjustment.

预浸料粘性：机制、测量和制造影响的回顾

预浸料的粘性（tack）被认为是通过自动铺层工艺（例如自动纤维铺放 (AFP) 或自动铺带 (ATL)）成功制造高质量复合材料的决定性材料特性。预浸料粘性的不利控制很容易导致层压板缺陷或机器故障，考虑到这些过程的巨大机械和材料成本，这是非常不可取的。预浸料粘性受粘合剂和内聚现象的复杂相互作用控制，这些现象受生产过程的机器和环境参数以及预浸料材料本身的固有特性的影响。本综述旨在提供对预浸料粘性研究现状的简要见解。所以，实验研究包括讨论使用的粘性测量方法以及预浸料粘性的模型方法。这些发现是在基本机制、影响参数的强烈相互依赖性以及通过工艺调整将测量的粘性数据转化为增强的 AFP/ATL 工艺稳定性的挑战的背景下进行讨论的。
