摘要

通过试验探究不同密度和含水率对竹基纤维复合材料的静曲强度（modulus of rupture，MOR）以及弹性模量（modulus of elasticity，MOE）的影响，并建立密度和含水率对MOR以及MOE影响的预测模型。结果表明，在测试区间内试板的密度与抗弯性能呈正相关；随着含水率升高，试板抗弯性能先增大后减小。根据预测模型，压制密度1.17 g/cm,3,、含水率11%左右的板材可以获得较高的MOR，大约为151.32 MPa；压制密度1.20 g/cm,3,、含水率10.65%左右的板材可以获得较高的MOE，大约为19.68 GPa。该研究为提高竹基纤维复合材料的抗弯性能以及生产实践提供一定理论指导。

Abstract

This paper investigated effects of different densities and moisture contents on the modulus of rupture (MOR) and modulus of elasticity (MOE) of bamboo-based fiber composite panels. A predictive model was developed to predict the effects of density and moisture content on MOR and MOE. The results showed that the density was positively correlated with the flexural properties of panels in the test range. With the increase in the moisture content, the flexural properties of the composite panels increased first and then decreased. Based on predictive model, the panels with the pressed density of 1.17 g/cm,3, and the moisture content of 11% obtain a higher MOR, which was 151.32 MPa. When pressed density was of 1.20 g/cm,3, and the moisture content was of 10.65%, the panel obtains a higher MOE of 19.68 GPa. The study provided reference for improving bamboo-based fiber composites flexural properties and a theoretical guidance for practical production.
