【摘要】：以慈竹(Bambusa distegia)为原料,探讨了浸胶方式对慈竹竹基纤维复合材料力学性能和耐水性能的影响。结果表明:采用一次浸胶的方式,随着胶黏剂固含量的增大浸胶量逐渐增加,力学性能和耐水性能随着浸胶量的增加而增强。采用二次浸胶的方式,板材的静曲强度和弹性模量整体差别不显著,耐水性能和内结合强度随着第二次浸胶胶液固含量的增加而增强。采用二次浸胶的方式压制的竹基纤维复合材料较一次浸胶的相比,可以在保持板材强度的情况下,提高板材的耐水性能,同时大幅降低浸胶量,从而节省板材的压制成本。
[Abstract]:(Bambusa DISTEGIA) with bamboo as raw material, to investigate the effect of dipping method on the mechanical properties and water resistance of bamboo bamboo based composites. The results show that using a dipping method, with the increase of solid content of the adhesive glue content gradually increased, the mechanical properties and water resistance properties increased with dipping the amount of two. The dipping method, the overall difference between the static bending strength and elastic modulus of the plate is not significant, the water resistance and internal bond strength increased with second dipping glue solid content. By pressing two dipping way based on bamboo fiber composite material is a dipping compared, can keep the plate strength, improve the water resistance of the sheet, and greatly reduce the resin content, thus saving the cost. Pressing plate
