Experimental fatigue tests performed on riveted carbon fiber laminates showed that the specimens, after some thousands of cycles, heated up, reaching around the rivet holes high temperatures. These temperatures if not properly controlled could be detrimental for the joint health. In order to understand the relative importance of all the mechanical and geometric parameters involved in the joint manufacturing, a numerical model of the joined carbon fiber laminates was developed using a commercial finite elements code. A simplified analytical model of heat transfer was then used to simulate the rivets thermal behavior under the assigned operating conditions: this model allowed comparisons with finite elements and can be used for simple thermal simulations. The numerical and analytical results were found in a good agreement with the available experimental results. The present research conclusions can be used for drawing better design rules in the definition of riveted carbon fiber laminates.

航空航天应用铆接碳纤维层压板的热力学分析

对铆接的碳纤维层压板进行的实验疲劳测试表明，经过数千次循环后，试样升温，达到铆钉孔周围的高温。如果控制不当，这些温度可能对关节健康有害。为了了解接头制造中涉及的所有机械和几何参数的相对重要性，使用商业有限元代码开发了连接碳纤维层压板的数值模型。然后使用简化的传热分析模型来模拟指定操作条件下的铆钉热行为：该模型允许与有限元进行比较，并可用于简单的热模拟。发现数值和分析结果与可用的实验结果非常一致。目前的研究结论可用于在铆接碳纤维层压板的定义中绘制更好的设计规则。
