Study on ice adhesion of composite anti-/deicing component under heating condition

Abstract

An anti-/deicing component of composite materials for wind turbine blades is usually carried out under heating conditions. In order to study the ice adhesion properties of composite anti-/deicing component under heating conditions, an experimental platform for measuring ice adhesion force on composites was set up. Based on the heating parameters such as the heating temperature, heating voltage, and heating time, the experiments of ice adhesion of composite anti-/deicing component under deicing conditions were designed by orthogonal analysis. In this article, ice adhesion forces on composite anti-/deicing component were measured at −9.74°C, −11.58°C, −14.1°C, and −16.84°C by the proposed experiment platform, and the real ice adhesion forces under various heating parameters were measured. Through the analysis of experimental data and fitting method, the relationship between various factors and ice adhesion on composite anti-/deicing component was expounded. The influence weight of each heating parameter on the ice adhesion was analyzed. In addition, the mathematical model of ice adhesion on composite anti-/deicing component under deicing condition was established to describe the influence of deicing variables on ice adhesion in the experiments. According to the fitting function of the experimental data, the relationship between the heat consumption of composite anti-/deicing component and ice adhesion force in the process of heating is in accordance with the inverse power exponential expression, which reveals the internal relationship between ice adhesion force and energy consumption.
