This project aims to develop hybrid toughening technologies to overcome the major problem of transverse matrix cracking and splitting in existing carbon fibre composites when subjected to thermal-mechanical loading at the ultracold liquid hydrogen temperature. Nano-toughened thin-ply carbon fibre layers will be hybridised with standard-ply laminates to sustain internal pressure and external impact loading at cryogenic temperatures without leaks. The hybrid composites are expected to enable Australian companies to engineer, manufacture and export lightweight carbon fibre tanks for storing and exporting liquid hydrogen, which is emerging as a transformational opportunity for Australia to become a global supplier of green energy.

该项目旨在开发混合增韧技术，以克服现有碳纤维复合材料在超冷液氢温度下承受热机械载荷时横向基体开裂和分裂的主要问题。纳米增韧的碳纤维薄层将与标准层压板混合，以在低温下承受内部压力和外部冲击载荷而不会泄漏。混合复合材料预计将使澳大利亚公司能够设计，制造和出口用于储存和出口液氢的轻质碳纤维罐，这正在成为澳大利亚成为全球绿色能源供应商的转型机会。
