The project “Life Cycle Technologies for Hybrid Structures” (LCT) aimed to develop methods and technologies that are functional, economical, and environmentally beneficial throughout their entire life cycle. The project focused in particular on the usage phase and end-of-life options, with the aid of targeted condition monitoring. An important component was a holistic ecological and economic evaluation using scenario-based life cycle assessment (LCA) / life cycle costing (LCC).
As part of the project, a methodology for the life cycle-spanning design of technologies was developed that took economic, ecological, and functional criteria into account. It was exemplarily geared toward hybrid structures in vehicle construction and was tested and validated during the course of the project. Through the continuous integration of collected data, the model quality was gradually improved. In addition, an application-oriented guide was created that summarized the key findings on the life cycle-spanning design of hybrid structures.
The content developed can be divided into six sub-results: First, a concept for production-accompanying data collection and evaluation was developed, which enabled statements to be made about life cycle performance. Second, a test approach was developed to map the usage phase using suitable aging and damage tests and accompanying test procedures. Third, the reparability of damaged components was investigated and evaluated in terms of functionality, ecology, and economy on the basis of coupon samples. Fourth, a multiscale model was developed that mapped the component life cycle, including relevant boundary conditions, and allowed the integration of real test data. Fifth, a comprehensive LCA and LCC of the demonstrator components was carried out, taking into account uncertainties and varying boundary conditions. Finally, this work resulted in a guideline documenting the application of the methodology for various technology designs.
