应我校机械工程学院方素平教授邀请，日本京都大学北条正树教授将来我校进行学术交流，并为我校师生举办学术讲座。讲座的相关安排如下：

一、讲座题目：Recent Advances in Carbon Fiber Reinforced Plastics

讲座人：北条正树 教授

时 间：10月17日上午9:00～11:00

地 点：西二楼机械学院第三会议室

内容简介：Carbon fiber reinforced plastics (CFRPs) have superior specific strength and stiffness. Their application is quite active in the aerospace area where the lightweight structures are critical. This lecture briefly review key characteristics and current status of advanced composite materials, and further research trends from the viewpoints of structural and material developments. First one is the development of crack arrester for sandwich structures, which are expected to realize the full potential capability of composite materials. The second one is the novel through-the-thickness reinforcement technique for laminates, which is expected to improve the weakest point of common laminated structures of CFRP.

二、讲座题目：In-situ observation of interfacial fatigue crack propagation in microscopic model composites using bifiber specimens

讲座人：北条正树 教授

时 间：10月18日上午9:00～11:00

地 点：西二楼机械学院第三会议室

内容简介：Interfacial fatigue crack growth behavior in GF/epoxy model composites was investigated using bifiber shear (BFS) specimens in a scanning electron microscope. The specimen is composed of two E-glass filaments with diameters of 23 and 40 m, and bisphenol A type epoxy is impregnated between the filaments. The crack growth behavior under different stress ratios was investigated to clarify the fatigue crack growth mechanism. The change in the crack growth rate, da/dN, was not monotonic with crack length, suggesting a variation in the resistance to fatigue crack growth along a single filament. The resistance to fatigue crack growth of the interface is much smaller than that of composite laminates. The fatigue crack growth mechanism of the glass fiber/epoxy interface under different stress ratios is controlled by the maximum energy release rate, Gmax, which is completely different from that of composite laminates.
