Bouligand结构可以改善现有材料的机械性能。然而，目前大多数研究主要集中在常温环境下利用 Bouligand 结构改善材料性能，而忽视了湿热环境下性能的减弱。因此，我们选择具有天然单向结构的高亲水性竹子作为原料，制备具有Bouligand结构的竹复合材料层压板。研究了湿热环境对 Bouligand 结构层压材料力学性能的影响。结果表明，Bouligand结构受湿热环境影响较大，且螺旋铺设角度越小，湿热环境对力学性能的影响越小。另外，在湿热环境下，铺层角度为10°时，层压材料的弯曲强度和冲击强度与室温相比分别下降了11.45%和11.57%，表明螺旋铺层角度大大降低了层压材料的抗弯强度和冲击强度。影响高温和潮湿环境下的机械性能。这项研究深入探讨了 Bouligand 结构在改善炎热和潮湿环境中材料性能方面的应用。

Fiber-reinforced sustainable biomimetic Bouligand structures for hot and humid environments

The mechanical properties of existing materials can be improved with the Bouligand structure. However, most current studies mainly focus on improving material properties with Bouligand structure in ambient temperature environments and neglect the weakening of the properties in hot and humid environments. Thus, we chose bamboo, which is highly hydrophilic with a natural unidirectional structure, as the raw material to prepare bamboo composite laminates with the Bouligand structure. The effect of humid and hot environments on the mechanical properties of laminated materials with the Bouligand structure was investigated. The results showed that the Bouligand structure was greatly affected by the humid–hot environment, and the smaller the laying angle of the spiral, the lesser the effect of the humid–hot environment on the mechanical properties. Additionally, in the hot and humid environment, the bending strength and impact strength of the laminated materials decreased by 11.45% and 11.57%, respectively, at a layup angle of 10° compared with those at room temperature, indicating that the spiral layup angle greatly impacted the mechanical properties in hot and humid environments. This study provides insight into the application of the Bouligand structure in improving material properties in hot and humid environments.
