Onset Theory: Pushing the design envelope for textile composite structures

这项研究旨在开发一种创新的基于物理学的方法来预测纺织复合材料的强度。这在飞机设计等领域尤为重要，在这些领域，需要大幅减轻重量，以使设计师在低碳未来保持竞争力。改进的理论和设计工具将消除保守主义，并在很大程度上解释这些重量节省。新方法是第一个在从原子到飞机的所有长度范围内保持一致的方法，确保了与新的和不断发展的复合材料系统的相关性。对纺织层压板中裂纹萌生的新理解旨在减少新飞机的设计和认证工作，并有助于以较低的成本设计更高效的机身。

This study aims to exploit an innovative physics-based approach to predict the strength of textile composites. This is particularly important in areas such as aircraft design, where drastic weight savings are needed to allow designers to remain competitive in a low-carbon future. Improved theory and design tools will remove conservatism and account for a large part of these weight savings. The new approach is the first to be consistent at all length scales — from atoms to aeroplanes — ensuring relevance for new and evolving composite material systems. A novel understanding of crack initiation in textile laminates is intended to reduce design and certification effort for new aircraft and help to design more efficient airframes at a lower cost.
