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.**************

尽管木质轻质夹芯板 (LWSP) 的概念已经存在很长时间，但 LWSP 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，如今大多数 LWSP 由两种强大的材料组成。薄面板粘在厚的轻质芯上，其中两种成分可以是木材、塑料和/或金属。****Corruven Canada Inc.（以下简称 Corruven）位于新不伦瑞克省埃德蒙斯顿，最近凭借其专利的Corruven®核心技术开发了一系列基于木皮的轻质复合板，该核心技术已用于开发具有不同应用的LWSP，希望与新不伦瑞克大学木材科学技术中心合作。开展一个研究项目，旨在优化 Corruven LWSP 的结构和性能，用于脚手架板和墙壁系统等结构应用。** **拟议项目将研究在建筑中使用 LWSP 的可行性在该项目中，将研究生产变量和边缘材料对面板性能的影响，因为 Corruven 面板的核心具有特殊的配置/形状和材料，因此它们不属于 中定义的任何类别。因此，还将提出修改后的测试方法来评估 Corruven LWSP 的刚度、负载能力和粘合质量方面的结构性能，该项目的结果将有助于 Corruven 将其市场扩展到建筑领域。此外，让加拿大的木制品行业更具全球竞争力。****************
