- Abstract
Detonation gun (D-gun) spraying technology was utilized to fabricate Al coatings on modified polymer matrix composite substrates. Prior to the application of the D-gun-sprayed Al coating, an epoxy-Al-mixed layer was directly sprayed onto the laminates surface and cured without sandblasting. The properties of the coatings were characterized utilizing scanning electron microscope, transmission electron microscope, x-ray diffraction, and mechanical testing. The results indicate that well-bonded, polycrystalline Al coatings were fabricated by D-gun spraying technique. The addition of the mixed epoxy-Al-mixed transition layer significantly improved the bond strength of the D-gun-sprayed Al coating on the carbon fiber-reinforced polymer (CFRP) substrate from 8.6 to 21.5 MPa. Moreover, carbon fiber damage was rarely detected in the precured CFRP coupons, indicating less mechanical property degradation of the modified CFRP than that of the traditional sandblast pretreatment.
