The effect of fibre laser surface treatment with different energy densities on the surface microstructure and bonding performance of a carbon fibre reinforced polymer (CFRP) composite was investigated. Results indicate that the effect of laser surface treatment on the CFRP with a defocusing amount of 4 mm is the optimal. With increasing energy density the resinremoval degree of the CFRP structure surface increases gradually, the surface free energy of CFRP greatly increases and the contact angle of CFRP decreases. At the same time, the high energy density will lead to the fibre being easily damaged. A combined mechanism of laser treatment on CFRP is discussed. [ABSTRACT FROM AUTHOR] |
