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.

本研究旨在利用一种创新的基于物理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，因为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性，并占重量节省的很大一部分。新方法是第一个在所有长度尺度上保持一致的方法-从原子到飞机-确保与新的和不断发展的复合材料系统相关。对织物层压板裂纹萌生的新认识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有效的机身。
