The production of new sandwich structures, such as those used for example for modern aircraft and vehicles require different heating processes. An infrared system from Heraeus Noblelight offers the necessary flexibility for both trials and for later production. From the Institute of Lightweight Structures and Polymer Technology (ILK) of the TU Dresden as could new combination method such as the thermal pressing, be improved. The ILK has the novel manufacturing processes so implemented that they are now economically viable and are nearing production readiness.
Foam technologies are used increasingly in the future as can improve the performance of components with the new composite technologies and new applications are possible. The requirements for the components are going to increase the functionality and integration capability, while reducing component weight and manufacturing costs.
When thermopressing organic sheets are connected to foam board. For this, the sandwich of thermoplastic cover layer and core material is produced and transformed directly in the pressing tool. Heated semi-finished products are transported in a pressing tool with foam panels, which are covered above and below with Organoblechzuschnitten. When the tool is the outer layers and the foam core are formed and pressed to form a sandwich structure.
Infrared systems transfer heat without contact medium, by means of electromagnetic waves that produce heat directly in the material.
Infrared systems provide a very flexible adjustment and control of power. They also have very short response times, short-wave and carbon emitters react within one to three seconds. This makes heat controllable and helps to realize temperature profiles.
This flexibility of infrared systems makes them an ideal source of heat in the design phase of new technologies.
