CompActive designs and manufactures active components and systems based on shape memory alloys (SMA). With our actuator principle, we enable adjustment functions that can be implemented with minimal installation space, minimum weight and with a gap-free and kink-free contour. As a result, the technology offers new opportunities for innovative applications in a cross-industry environment. CompActive provides all steps from idea to modules for series application from feasibility studies, setup of functional prototypes and detailed design to manufacturing of active modules.
Shape memory alloys are metals that can generate large changes in geometry even at low temperature changes. Due to the direct integration of the actuator – the shape memory alloy elements – into a fiber-plastic composite, the actuator system is transferred to the hybrid structure and an active shape adaptation of the component is possible. The tailor-made hybrid assembly with integrated actuator elements offers a number of advantages by dispensing with a mechanical system with mechanical couplings and local load introduction points. With this scalable actuator principle, it is possible to use an adjustment function for:
- minimal space
- lowest weight and
- gap-free and kink-free contour
to realize.
These unique advantages make the technology of active hybrid composites a key to innovative functions that are not possible in the conventional way. Depending on the field of application and implemented functions, the active hybrid assemblies are able to increase the performance, efficiency and / or comfort of technical products.
