REPARATURSYSTEM FÜR VERBUNDMATERIAL MIT Z-FÖRMIGEN KLAMMERN

摘要

The strength of composite patches is improved over conventional bolted or bonded patches by including Z-pins in the patch/parent structure interface to provide a mechanical link with small stress concentration between the patch and the parent structure. In some cases, we achieve a stronger repair removing the pins to leave holes that fill with resin from the patch during the curing or bonding operation.
