Abstract



For this study, woven glass and carbon fibres
reinforced composite materials were produced. Composite materials have been
produced with eight laminates.  For
experimental study, specimens with 10 mm internal hole were prepared. Then, these
specimens were repaired by using adhesive and composite patches with different
repair parameters. Two different bonding patch type were used for external
bonding patch repair of the specimens. These were wet lay out patches and
prepreg patches.  Test specimens were
prepared in necessary curing temperatures and laboratory conditions. By
performing the unidirectional tensile test to these specimens, the ultimate
failure loads of these repaired specimens were indicated. By comparing these
ultimate failure loads of repaired specimens that prepared with various
parameters, the effects of several repair parameters on the ultimate failure
strength are investigated. These repair parameters are patch bonding area (D/W
ratio), bonding length, adhesive thickness and patch thickness.
