Development of wood-based lightweight sandwich panels for structural applications

虽然木质轻质夹心板（LWSPs）的概念已经存在了很长时间，但LWSPs在不同的应用中越来越受欢迎，例如航空航天，运输，门，家具和运动器材。今天，大多数lwsp由两个坚固的薄面板粘在厚的轻质核心上组成，其中两种成分可以是木材，塑料和/或金属。****位于新不伦瑞克省埃德蒙斯顿的瓦楞加拿大公司（以下简称瓦楞）最近开发了一系列以其获得专利的瓦楞®核心技术为基础的木饰面轻质复合板。核心技术已被用于开发具有不同应用的lwsp。瓦楞公司希望与新不伦瑞克大学木材科学技术中心合作，开展一项研究项目，旨在优化瓦楞公司lwsp的结构和性能，用于脚手架板和墙壁系统等结构应用。** **拟议的项目将调查在建筑中使用具有室外和室内高性能的lwsp的可行性。在这个项目中，将研究生产变量和边缘材料对面板性能的影响。由于瓦楞纸板的芯材具有特殊的配置/形状和材料，因此它们不属于ASTM测试方法中定义的任何类别。因此，还将提出改进的测试方法，从刚度、承载能力和粘结质量等方面评价瓦楞钢板的结构性能。该项目的成果将有助于瓦楞纸板将其市场扩展到建筑行业，并进一步保持加拿大木制品行业在全球的竞争力。**************

Although the concept of wood-based lightweight sandwich panels (LWSPs) has been around for a long time, LWSPs have been gaining popularity in different applications, such as aerospace, transportation, door, furniture and sports equipment. Most LWSPs today consist of two strong thin face sheets glued to a thick lightweight core where both constituents can be of wood, plastics, and/or metal.****Corruven Canada Inc. (hereafter Corruven) located in Edmundston, New Brunswick, has recently developed a series of wood-veneer-based lightweight composite panels with its patented Corruven® Core Technologies. The core technologies have been used to develop LWSPs with different applications. Corruven, would like to collaborate with the University of New Brunswick's Wood Science and Technology Centre to conduct a research project with an aim to optimize the structure and properties of Corruven's LWSPs for structural applications such as scaffold planks and wall systems.** **The proposed project will investigate the feasibility of using LWSPs in construction with high performance in both outdoor and indoor. In this project, effects of production variables and edging materials on panel properties will be studied. Since the cores of Corruven's panels have special configurations / shapes and materials, they do not fall in any category defined in ASTM test methods. Therefore, modified testing methods will be also proposed to evaluate the structural performance of Corruven's LWSPs in terms of stiffness, load capacity and bond quality. The outcomes from this project will help Corruven expand its market to construction sector, and furthermore keep Canada's wood products industry more competitive globally.**************
