Application research of laser treatment in the wind turbine blade pultruded planks
摘要
Abstract
When forming wind turbine blades,the pultruded planks were usually stacked on the blade skin,and the bonding between the pultruded planks and the skin,as well as between the pultruded planks,were comple-ted by injecting resin.However,if the bonding effect between interfaces was not good,there is a risk of detachment.Against this background,this article studied the application of laser treatment in wind turbine blade pultruded planks.By analyzing the tensile and shear properties,interlaminar shear test(pultruded plank+laminate),and surface morphology of plates under different processing speeds,the optimal CO2 laser processing speed was explored and the surface functional groups,roughness,mechanical properties,and secondary bonding properties of pultruded planks treated with laser and peel ply were compared.The results showed that when the processing power was 100 W and the processing speed was 1 500 mm/s,the resin on the surface of the board was ablated,and the fibers were exposed without any damage,making it the optimal combination of process parameters for the experiment.The pul-truded planks treated with the optimal combination of laser process parameters achieved roughness,mechanical properties,and secondary bonding performance equivalent to that of the peel ply treatment.Laser surface treatment technology has fast processing speed,helps to increase extrusion speed,and can avoid the disadvantages of waste,environmental pollution and not conducive to increasing extrusion speed and efficiency caused by peel ply treatment process.It provided a new idea for the surface treatment process of pultruded planks.关键词
