Studying the effect of acetylation Beech on interfacial bonding resistance of transparent paint (nitrocellulose lacquer, asid catalyzed lacquer and Half Ppolyester)

In this study, structural performance of corner joint reinforced by fiber reinforced polymers (FRP) at the area of maximum tension stress was investigated under diagonal tension loading. Therefore 1 to 3 layers of unidirectional woven Glass, Carbon and Kevlar fibers were used and hand lay-up was don...
