摘要

由木材工业产生的较短的锯木材材料被认为是废物;因此定期被锯木厂倾倒。手指连接,一种方法连接在一起的小块木材被认为是一种声音的技术,以减少浪费。在这个过程中,不同种类的木材被粘合在一起,制成指缝板。在这方面,选择最好的木材品种组合是至关重要的,因为成功在很大程度上取决于木材的机械性能。本研究以32种常用木材为研究对象,建立了基于木材强度特性的木材分类体系。采用聚类分析对强度性状相近的树种进行分组。据此,将木材种类分为极低、低、中、高和极高五个强度等级。强度指数与木材密度之间也存在显著相关(P = 0.000)。

Strength index-based timber classification of Sri Lankan timbers and potential for finger-joint production from wood off-cuts
ABSTRACT Shorter sections of sawn timber material resulted from timber industry are considered to be wastes; thus regularly dumped by sawmills. Finger-joint, a method which connects two small pieces of timber together is recognized as a sound technique to minimize the wastage. In this process, sections of different timber species are bonded together for making finger-joint boards. In this connection, selection of the best possible combination of timber species is vital as the success largely depends on the mechanical properties of the pieces. In this study, commonly used 32 timber species were employed to develop a timber classification system based on strength properties of timber species. Cluster analysis was used in grouping the species with similar strength properties. Accordingly, timber species were grouped into five strength classes as very low, low, medium, high and very high. A significant correlation (P = 0.000) between the strength index and timber density was also observed.
