Abstract
A joining method and assembly for an aircraft. To improve the characteristics or permit hitherto impossible connections between thermoplastic and thermoset components, a multi-material joining method is disclosed in which a thermoplastic connecting region is formed on the thermoplastic component. The connecting region is connected to the thermoset component by interdiffusion. For this purpose, the uncured second component is brought into contact with the connecting region and heat is supplied. An interdiffusion layer is formed which fixedly connects the second component and the connecting region to one another and thus joins the first component to the second component.
Claims15
A joining method for joining a fiber-reinforced, first component, which contains a first polymer material as matrix, to a fiber-reinforced second component, which contains a curable thermosetting second polymer material as matrix, the method comprising:
- a) providing the first component;
- b) forming a connecting region on the first component to generate a joining surface on the first component, the connecting region comprising one or more thermoplastic polymer materials and being formed with at least one of:
- ba) the connecting region is formed with a plurality of adjacent spatial regions, two adjacent spatial regions in each case comprising different thermoplastic polymer materials;
- and/or
- bb) the connecting region is formed with a surface structure region which has periodic elevations and indentations in at least one direction;
- and
- c) arranging a region of the second component to be in contact with the joining surface and supplying heat to fix the connecting region to the second component while curing the second polymer material to join the first component to the second component.
