摘要/Abstract

摘要： 针对大型风电叶片用真空灌注型环氧树脂体系,将国产高性能环氧树脂体系MERICAN 3311A/B与国外同类某产品进行了同等实验条件下的对比分析,分别考察了两种树脂体系的基本特性、增黏曲线、放热峰、凝胶时间和机械性能等。结果表明,该环氧树脂体系具有粘度低、适用期长、放热峰低、中高温固化快且固化物机械性能高等优点,符合GL认证的相关要求,并且已经达到甚至在某些方面已超越国外同类进口产品的水平,可完全满足大型风电叶片用真空灌注型树脂的要求。

关键词: 大型风电叶片, 环氧树脂, 放热峰, 机械性能

Abstract: In this work, two kinds of vacuum infusion epoxy resin systems, i.e. the domestic product MERICAN 3311A/B and the imported product, were comparatively analyzed with each other under the same experimental conditions for large-scale wind turbine blades application. The basic characteristics, viscosity change profiles, exothermal peak, gelation time and mechanical properties of both epoxy resin systems were systematically studied. The results indicated that, the domestic product MERICAN 3311A/B possessed a lot of advantages, such as low viscosity, long pot-life, low exothermal peak, fast curing at medium-high temperature and excellent mechanical properties, which were totally in accordance with the GL certification requirements. Besides, the properties of the domestic product MERICAN 3311A/B already reached or even partially exceeded the level of the imported product. Therefore, it can be concluded that the domestic product MERICAN 3311A/B can meet the requirements for the performances of epoxy resin used in large-scale wind turbine blades.

Key words: large-scale wind turbine blade, epoxy resin, exothermal peak, mechanical property
