In 1999-2000 Australia spent $19 billion on civil engineering infrastructure renewal (3% of the country's GDP). The repair of damaged structures and strengthening of existing structures has become a research priority to maximise the life of aging infrastructure. A method that shows particular promise is the use of CFRP technology to retrofit structures. The repair technology, however, requires development and questions remain as to bonding mechanics and debonding strength of the repair material from the structure. This research will provide high quality experimental data and will develop a rational analytical model for debonding between CFRP plates from the parent concrete.

1999-2000年，澳大利亚在土木工程基础设施更新上花费了190亿澳元（占该国国内生产总值的3%）。修复受损结构和加强现有结构已成为研究重点，以最大限度地延长老化基础设施的寿命。一种特别有希望的方法是使用CFRP技术来改造结构。然而，修复技术需要发展，并且关于修复材料与结构的粘结力学和脱粘强度仍存在问题。这项研究将提供高质量的实验数据，并将开发一个合理的分析模型之间的剥离CFRP板从母体混凝土。
