The effect of repair using thermal fusion bonding (TFB) on residual compressive strength was investigated in carbon fiber reinforced polyamide 6 (CF/PA6) cross-ply laminate with several impact damage. Cross-ply laminates with different ply-thickness (0.04 mm and 0.12 mm) were prepared in order to investigate the influence of the different impact damage due to ply thickness. The experimental results indicated that TFB was shown as one of the effective methods to repair the impact damage caused by matrix failure and to recover the compressive strength. On the other hand, TFB was not effective to decrease in compressive strength caused by fiber breakage due to buckling before reaching compressive strength of intact specimen.
