- Abstract
In this work, FRP panel surface was treated by 12 plasma techniques formed by a pairwise combination of four power consumptions (300W, 400W, 500W, and 600W) and three transmission velocity (2.5m/min, 5.0m/min, and 7.5m/min) respectively, and then adhere to timbers. According to delamination test dates, 7 of 12 specimen groups meet the requirement. Shear strength at dry state of composite – FRP/wood –was improved. Mode GIIC of 4ENF for the composite fracture toughness test was inferred in this paper. Variance analysis results demonstrated that power and velocity interaction has significant influence on delamination properties of FRP-wood interface, and power has significant influence on shear strength and fracture toughness. Considering strength and toughness synthetically, the optimized process of plasma treatment on FRP surface could be concluded, which power consumption was 300W, transmission speed was 5.0m/min. With this process, the properties of the composite interface are as following: the average shear strength at dry state was 9.46MPa, 6.49MPa at wet state, the GIIC was 0.94kJ/m2, and the average delamination ratio was 1% and 3% after soaked in normal and boiling water, which are all meet the request of standard.
