Abstract: Wind power,as a clean and renewable energy form,is being widely utilized. The blades,serving as the core components of wind turbines,demand paramount importance in structural safety. In blade structural design,engineers must consider both the mechanical properties of the materials themselves and the interfacial bonding performance between different materials,ensuring synergistic effects when composite materials work collaboratively. As the most commonly used reinforcement material in blades,the bonding performance between fiberglass fabric and other materials proves particularly critical. Given the diversity of fiber fabrics,this study focuses on investigating how different yarn orientations in fiber fabrics affect the bonding performance of various types of interfaces,aiming to provide theoretical guidance for blade design.

Key words: wind turbine blade, fiberglass fabric, interfacial performance
