Both wood and bamboo are renewable anisotropic materials with a long application history in human society. Engineered wood or bamboo aiming to mitigate the variability of the natural material can provide better material properties and structural performance, compared to original sawn lumber or raw bamboo. In this paper, a state-of-the-art review was conducted on three types of novel engineered wood composites, namely fiber reinforced polymer (FRP) reinforced glulam, cross-laminated timber (CLT), and wood scrimber, as well as three types of novel engineered bamboo composites, namely laminated bamboo lumber (LBL), glued-laminated bamboo (glubam), and bamboo scrimber, with particular attentions to their manufacturing technologies, modeling approaches, and mechanical properties. Then, for these novel engineered wood/bamboo composites, a comprehensive comparison was conducted on their mechanical properties and on their densities. Finally, several cases of structural applications were respectively illustrated, in which these aforementioned engineered wood/bamboo composites were adopted as main building materials. Potentials of applying these engineered wood/bamboo composites for structures were confirmed, and their possible existing drawbacks were also discussed.

用于结构应用的新型工程木和竹复合材料:最先进的制造技术和机械性能评估

木材和竹子都是可再生的各向异性材料,在人类社会中具有悠久的应用历史。与原始的锯材或生竹相比,旨在减轻天然材料变异性的工程木材或竹子可以提供更好的材料性能和结构性能。在本文中,对三种新型工程木复合材料(即纤维增强聚合物(FRP)增强的胶合层,交叉层压木材(CLT)和木模)进行了最新的研究,以及三种新型工程竹复合材料的类型,即层压竹木(LBL),胶合层压竹(glubam)和竹板,尤其要注意其制造技术,建模方法和机械性能。然后,对于这些新颖的工程木/竹复合材料,对它们的机械性能和密度进行了全面的比较。最后,分别说明了几种结构应用案例,其中采用了上述这些工程木/竹复合材料作为主要建筑材料。证实了将这些工程木/竹复合材料应用于结构的潜力,并讨论了它们可能存在的缺点。
