Study on Bonding Performances of Air Plasma Treated FRP

Abstract:

Article Preview

This paper reports on the effect of air plasma on the FRP surface wettability via change of the water contact angle. The aim is to alter the surface in a manner and scale resulting in stronger bonding strength between FRP and wood. The specimens are exposed to the direct current discharge. The irradiation time and power are variables. Goniometry is employed to determine the contact angle of FRP surface. The plasma treatment leads to radical generation and activation of such agents as oxygen, thus the surface contact angle decreases significantly. The shear strength of samples of wood reinforced by treated FRP is also given to show the bond quality at the FRP-wood interface.
