ADHESIVE JOINT FOR JOINING COMPONENTS OF TRANSPORT CRAFT, IN PARTICULAR OF AIRCRAFT, AND METHOD FOR DETERMINING MINIMUM MECHANICAL LOAD CAPACITY AND/OR MECHANICAL STRENGTH OF AN ADHESIVE JOINT

摘要

This invention relates to an adhesive joint 3, 11 for joining components 1, 2,9, 10 oftransport craft, in particular of aircraft, wherein the adhesive joint 3, 11is formed byan adhesive means 4, 12. According to the invention, the adhesive means 4, 12hasseveral functional elements 6-8, 14-16, 19-24 with actuatory and/or sensoryproperties, in particular for enabling a minimum mechanical load capacity oftheadhesive joint 3, 11 and/or detecting a mechanical loading state in theadhesive joint3, 11. Due to the presence of the functional elements 6-8, 14-16, 19-24integrated inthe adhesive joint 3, 11, direct and simple testing of the mechanical loadcapacity ofthe adhesive joint 3, 11 is possible without costly external test structures,e.g. in theform of measuring and testing systems for conducting tensile load tests or thelike.Moreover, mechanical stress states in the adhesive joint 3, 11 can bedetected.Moreover, the invention relates to a method for determining a minimummechanicalload capacity and/or mechanical strength of an adhesive joint 3, 11 forjoiningcomponents 1, 2, 9, 10 of transport craft, in particular of aircraft, whereinin anadhesive joint 3, 11 formed by an adhesive means 4, 12, several functionalelements6-8, 14-16, 19-24 with actuatory and/or sensory properties are integrated,comprisingthe following steps:- coupling a control signal into the functional elements 6-8, 14-16, 19-24,and- increasing the control signal up to a limiting value.By the inventive method, it is moreover possible to detect also mechanicalstressstates in the adhesive joint 3, 11.
