本工作旨在研究可逆热塑性粘合剂的愈合潜力。粘合剂可通过使用感应加热系统来活化，该感应加热系统可在整个电磁场中在颗粒中感应热，因此它们可熔化粘合剂以用于粘合或分离过程。愈合过程包括用准静态和疲劳测试破坏单搭接接头（SLJ）样本，然后使用感应器产生电磁场，该电磁场能够将粘合剂加热到其熔点，以便愈合受损的SLJ样本。对受损和愈合的样本进行SLJ测试，以分别评估受损样本的残余力学性能和愈合后的力学性能。SLJ试验表明，愈合过程可以完全恢复受损胶接接头的刚度，最大剪切强度和SLJ吸收的能量的很大一部分。这项工作还表明，重新粘接完全失败或分离的SLJ的可能性，通过使用相同的程序。将愈合和重新粘合后SLJ的机械性能与原始样本上的SLJ进行比较，以评估恢复的机械性能。
This work aims to study the healing potential properties of a reversible thermoplastic adhesive. The adhesive is activable by using induction heating systems that can induce thermal heat in the particles throughout the electromagnetic field so they can melt the adhesive for bonding or separation procedures. The healing procedure consists of damaging single lap joint (SLJ) specimens with quasi-static and fatigue tests and then using an inductor to generate an electromagnetic field able to heat the adhesive to its melting point in order to heal the damaged SLJ specimens. SLJ tests were performed on damaged and healed specimens to assess, respectively, the residual mechanical properties of the damaged specimens and the mechanical properties after healing. SLJ tests showed that the healing procedure can completely recover the joint stiffness of the damaged adhesive joints, a huge part of the maximum shear strength and the SLJ absorbed energy. This work shows also the possibility of re-bonding completely failed or separated SLJs by using the same procedure. The mechanical properties of SLJs after healing and re-bonding are compared to the SLJ compared on virgin specimens to assess the recovered mechanical properties.
