摘要: 本文介绍了风电叶片用拉挤板的国内外研究发展历程及现状,共涉及五种不同材料体系的拉挤板,分别为碳纤维拉挤板、玻纤拉挤板、碳玻混拉挤板、免脱模布拉挤板及聚氨酯拉挤板。分析了拉挤板相比较于传统的真空灌注、预浸料复合材料的应用优势和面临的挑战。结合目前应用现状,针对各种材料体系的拉挤板分别提出了未来重点关注方向和发展趋势:玻纤拉挤板因其低成本的优势,在未来陆上风电叶片中仍会占据主流,并将向更高模量及更低成本的方向发展;随着海上风电的发展及碳丝国产化进程加速,碳纤维拉挤板将会有更广阔的应用前景;碳玻混拉挤板、免脱模布拉挤板及聚氨酯体系拉挤板减重或降本优势明显,但仍需进一步开展应用研究。

Abstract: The research and development of pultruded plates for wind power blades at home and abroad are introduced in this paper. Five types of pultruded plates of different material systems are involved, which are carbon fiber pultruded plates, glass fiber pultruded plates, carbon fiber-glass fiber hybrid pultruded plates, pultruded plates without peel ply and polyurethane pultruded plates. The application advantages and challenges of pultruded plates compared with traditional vacuum filling and prepreg composites are analyzed. Combined with the current application status, the future focus direction and development trend of pultruded plates of various material systems are put forward respectively: Glass fiber pultruded plates will still occupy the mainstream in the future onshore wind power blades because of its low cost advantages, and will develop in the direction of higher modulus and lower cost; with the development of offshore wind power and the acceleration of the process of carbon wire localization, carbon fiber pultruded plates will have a broader application prospect; carbon fiber-glass fiber hybrid pultruded plates, pultruded plates without peel ply and polyurethane pultruded plates have obvious advantages in weight reduction or cost reduction, but further research and application experiences need to be carried out.
