ABSTRACT:
Irradiation of FRP surfaces by means of pulsed eximer lasers of from about 180 to 260 nm to etch or to photo ablative decompose the surface of the FRP parts without causing changes in the matrix of the FRP parts increases the adhesive potential of FRPs to structural adhesives. Thus, the bond between FRP parts is strengthened.
