Delignified wood (DW) retaining its microstructure has increasingly been used as an alternative to synthetic or natural fibers in the preparation of fiber-reinforced composites for novel light-transmitting, high-strength structural materials. In this study, wood laminated composite (WLC) was prepared by impregnating with cycloaliphatic epoxy resin (CAE) and laminating using DW as a continuous reinforcing fiber. Results showed that DW effectively strengthened the resin matrix, increasing the epoxy resin's strength by 25.44 %, while CAE modified the wood's opacity, achieving a transmittance of up to 74.83 %. The mechanical and optical properties of the WLC can be effectively tuned through various lamination combinations. Additionally, due to the UV curing properties of CAE and its infiltration of DW, uncured WLC had long-term shade storage capability and excellent processability. The WLC developed in this study combines good processing, mechanical, and optical properties, making it an attractive option for sustainable home decoration and lightweight structural materials.

一种透明、坚固、可模压的木质层压复合材料，作为可持续的装饰建筑材料


保留其微观结构的脱木质素木材（DW）越来越多地被用作合成或天然纤维的替代品，用于制备新型透光高强度结构材料的纤维增强复合材料。在这项研究中，通过用脂环族环氧树脂（CAE）浸渍并使用DW作为连续增强纤维进行层压来制备木质层压复合材料（WLC）。结果表明，DW有效强化了树脂基体，使环氧树脂的强度提高了25.44%，而CAE则修改了木材的不透明度，使透光率高达74.83%。 WLC 的机械和光学特性可以通过各种层压组合进行有效调整。此外，由于CAE的UV固化特性及其DW的渗透，未固化的WLC具有长期的遮光能力和优异的加工性能。本研究开发的 WLC 结合了良好的加工、机械和光学性能，使其成为可持续家居装饰和轻质结构材料的有吸引力的选择。
