The disclosure provides a mechanically fastened joint with an in-situ thermally cured seal. A method of installing and sealing a friction fastener to at least an upper substrate and a lower substrate includes providing an expandable sealant to an underhead volume of the friction fastener, installing the friction fastener through the upper substrate and into the lower substrate using a joining device, and applying heat in-situ to the expandable sealant such that the friction fastener is sealed to at least the upper substrate. The heat in-situ is applied to the expandable sealant via installing the friction fastener and/or with an external heating source disposed downstream from the joining device. 本公开提供了"利用原位热固化密封的机械紧固的接合部"。一种将摩擦紧固件安装到至少上基板和下基板并进行密封的方法，包括：向所述摩擦紧固件的头部下方体积提供可膨胀密封剂；使用接合装置将所述摩擦紧固件穿过所述上基板安装到所述下基板中；以及向所述可膨胀密封剂施加原位热，使得所述摩擦紧固件密封到至少所述上基板。经由安装所述摩擦紧固件和/或用设置在所述接合装置下游的外部加热源来向所述可膨胀密封剂施加所述原位热。
