Bonding of polymers and polymer composites with metal and with each
other
Teeth-shaped fins or pin fins on metal or polymer ensure anchor effect
bonding versus adhesion (in glue or glueless joints)
Fig.1 - Friction bearings with Teflon tape pressed into microgrooving
on internal surface
Fig.2- Microgrooving of polymers (teflon, UHMW-PE, and other low-adhesion
plastics) for gluing with metals, composites or other polymers
Fig.3
- Interlaminar shear in layers of carbon composite (CFRP) after
breakup.
No flaking-off from metal
Fig.4
- CFRP plated by stainless steel,
having DC - relief on the bonding surface after the impact test.
No flaking-off from metal
(metal -CFRR bonding was made by vacuum infusion)
