This proposal reviews and summarizes our recent efforts in nanostructuring multifunctional inter-phases, characterizing their structure and properties. Based on the progress made in the first funding period, the main goal of the intended research is to further develop fundamental knowledge on inter-phase phenomena of the most widely utilized glass fibre reinforced epoxy system. The work compri-ses mainly three parts: i) Structure: Interphase formation associated with nanoreinforcements, solid orientation/distribution/modification; ii) Properties: multiscale evaluation of both mechanical and physi-cal properties, with an emphasis on using interphase self-diagnosing capabilities as developed in the first funding period; iii) Characterization: mapping fundamental physical parameters and chemical composition of interphase. Various thermal/elasticity/electricity mapping techniques (nano-TA, force volume nanoindentation, electric force microscopy) are employed for collecting relevant data. In conclusion, the nanoscale dimensions, sensitive electronic detection, and flexible structure control of interphase between most widely used reinforcement-glass fibre and epoxy hold immense promise for new generations of composites with intelligent sensing capability.

该提案回顾和总结了我们最近在纳米结构化多功能中间相，表征其结构和性能的努力。根据第一个资助期取得的进展，预期研究的主要目标是进一步发展最广泛使用的玻璃纤维增强环氧树脂系统的相间现象的基本知识。这项工作主要包括三个部分：i）结构：与纳米增强材料相关的界面形成，固体取向/分布/修饰; ii）性能：机械和物理性能的多尺度评估，重点是使用第一个资助期开发的界面自诊断能力; iii）表征：绘制界面的基本物理参数和化学组成。各种热/弹性/电映射技术（纳米TA，力体积纳米压痕，电力显微镜）收集相关数据。总之，最广泛使用的水泥-玻璃纤维和环氧树脂之间的界面的纳米尺度，灵敏的电子检测和灵活的结构控制为具有智能传感能力的新一代复合材料带来了巨大的希望。
