Abstract

Lightweight engineering is a key technology on the way to achieve the EU 2030 targets that aim at least 40% cuts in greenhouse gas emissions from 1990 levels, at least 32% share for renewable energy, at least 32.5% improvement in energy efficiency, and 80% reduction of greenhouse gas emissions by 2050. Therefore, an urgent need is present for a deep market transformation by deploying efficient materials and technologies for different sectors like the automotive industry, the aerospace industry, wind energy and the construction sector [1]. Composite materials play a major role within that transformation process since they unite extraordinary properties with a low weight. The award lecture gives an overview about recent developments in the field of composite lightweight engineering. Using examples of promising developments such as carbon concrete composites [2], multifunctional carbon fibre composites from renewable resources [2,3], and novel textile composites for automotive applications [4]. Beyond that, scientific and industrial efforts to increase the lifetime of composite products are discussed. This includes in particular the use of predictive modelling for a degradation forecast of the material properties [5-7], the development of novel experimental methods [8,9], and diagnostics technologies for structural monitoring [10].
