Joining composite materials by means of reactive microparticles

Reactive systems generate high temperatures within a few seconds through exothermic reactions. Researchers of the Technical University of Munich use the energy from the reaction of the so-called reactive microparticles to create joints in plastics, metals or ceramics.
Joining Different Types of Material
Resource-efficient lightweight structures are a result of the targeted use of plastics, fiber-reinforced plastics or metals. However, joining materials of the same type or of different types is a key challenge in production engineering, as the joint partners can only be exposed to thermal or mechanical stress to a limited extent. Diverging thermophysical properties in particular, such as different coefficients of thermal expansion, make it more difficult to use conventional methods and demand innovative and adaptable joining technologies. Reactive systems, which react in an exothermic combustion reaction,enable a specific amount of heat to be released into the joint zone within a short...
