This study is a part of a project in developing natural fibre reinforced composite for wind turbine blade. The objective of this study is to evaluate the effect of fibre stacking sequence on flexural behaviour of the natural fibre reinforced composite hybridized with synthetic fibre. The flexural behaviour of the composite becomes an important consideration in deciding stacking sequence of the fibres. Material used in this study is polyester resin as the matrix. Jute, glass, and carbon fibres are used as the reinforcement. The composites were fabricated using vacuum bagging method cured at room temperature. The combinations of fibre as the reinforcement are configured by arrange two and three types of fibre. As a natural fibre, jute exists in all kind of combination. Flexural behaviour was observed using 3-point-bending test. The specimens were tested in accordance to the fibre stacking sequence. The result shows that stacking sequence of the fibres give significant different flexural behaviour regardless the effect of the fibre strength.

这项研究是开发用于风力涡轮机叶片的天然纤维增强复合材料项目的一部分。本研究的目的是评估纤维堆叠顺序对与合成纤维混合的天然纤维增强复合材料的弯曲行为的影响。复合材料的弯曲行为成为决定纤维堆叠顺序的重要考虑因素。本研究中使用的材料是聚酯树脂作为基体。黄麻、玻璃和碳纤维被用作增强材料。复合材料采用真空袋装法在室温下固化。作为增强材料的纤维组合由两种和三种纤维的排列构成。作为一种天然纤维，黄麻以各种组合形式存在。使用 3 点弯曲试验观察弯曲行为。根据纤维堆叠顺序测试样品。结果表明，无论纤维强度的影响如何，纤维的堆叠顺序都会产生显着不同的弯曲行为。
