了解未固化碳纤维预浸料的层间剪切行为是避免大规模部件制造过程中工艺缺陷的基础。将AS4/8552的剪切试验与一维粘弹塑性层间剪切模型进行了比较。本文提出了一种能够确定温度、速率和压力参数的方法，以使预浸料的运动阻力最小。单独研究节理强度和摩擦值表明，与以前的工作相反，摩擦随温度升高而增加，并且在较低温度下，节理强度的新值占主导地位。速率相关变量与树脂行为密切相关，这证实了粘弹性模型的必要性。讨论了在工业场景中的简单应用，以及更复杂的过程建模。
Understanding the inter-ply shear behaviour of uncured carbon fibre prepreg is fundamental to avoiding process-induced defects during manufacturing of large-scale components. Shear tests for AS4/8552 are compared to a one-dimensional viscoelastic–plastic model for inter-ply shear. The paper presents a methodology capable of determining the parameters of temperature, rate and pressure required for minimum resistance to movement of a prepreg. Investigating the joint strength and friction values individually shows that friction increases with temperature, contrary to previous work, and that the new value of joint strength is predominant at lower temperatures. Rate dependent variables are strongly linked to the resin behaviour, confirming the need for a viscoelastic model. Simple application to industrial scenarios is discussed along with more complex process modelling.
