Abstract
Fibre metal laminates based on titanium and carbon fibre reinforced polyimide (TCP-FML) are designed and manufactured to meet the requirements of high temperature applications. In this work, the preparation technology of the TCP-FML was optimized through the investigation of prepreg manufacture as well as surface treatment of titanium. Prepreg were manufactured using a solution dip method. The effects of step width, fibre tension and translational speed on the performance of prepreg were studied. Surface treatments were performed on titanium using sandblasting, chromic acid (CAA) anodization and NaTESi anodization methods. SEM observation and contact angle were used to analyze the surface characteristics of titanium. The effects of surface treatment on the interlaminar properties of titanium/polyimide were investigated by single-lap shear test and double cantilever beam (DCB) tests. This careful surface preparation, to ensure a good interfacial strength, is crucial for good mechanical properties.
