Abstract
Based on the material systems of TA2 foil, carbon fiber and PEEK, the preparation process of titanium foil-carbon fiber cloth-PEEK sheet directly composited by hot pressing method was investigated. After pre-treatment of ultrasonic cleaning degreasing and sandpaper polishing for the initial materials, the layers were manually laid and put into self-designed hot pressing moulds, and the TA2/ CF/ PEEK laminates were prepared by hot pressing method based on different temperatures (370 and 390 ℃), pressures (0. 8, 1. 6 and 2. 5 MPa) and holding time (20 and 40 min). The influence of hot pressing process parameters on the bending properties of laminates was investigated using the three-point bending experiment method. The results show that the better hot pressing process is: deformation temperature of 390 ℃, hot pressing pressure of 1. 6 MPa, holding time of 40 min and laying two resin films on each side. The TA2/ CF/ PEEK laminates prepared under this process have bending strength of 681. 68 MPa and bending modulus of 69.5 GPa.
