Adhesive laminating technology is one of the driving forces keeping Canada’s wood products producers competitive, and it relies on the production of high-performance and durable engineered wood products (EWPs). The bond quality of a laminated EWP product governs its service performance, which must be accurately evaluated. The requested equipment is a 3D Stereo Microscope Digital Image Correlation System, which is specially designed to meet the applicant’s research requirements. This system contains one stereo microscope and two digital cameras, accompanied by software for both 3D and 2D image analysis. This system can capture the initiation of a crack(s) along a bond line at a speed of more than 150 frames per second. In addition, this system can be used to measure the deformation and shape of relatively large specimens such as a beam or a wall without mounting a microscope. These outputs form the basis of understanding the bond quality of laminated wood products.

粘合剂层压技术是使加拿大木材产品生产商具有竞争力的驱动力之一，它依赖于高性能和耐用工程木制产品（EWP）的生产。层压的EWP产品管理员的键质量必须准确地评估其服务性能。请求的设备是一个3D立体显微镜数字图像相关系统，该系统专门设计以满足申请人的研究要求。该系统包含一个立体声显微镜和两个数码相机，由软件用于3D和2D图像分析。该系统可以以每秒超过150帧的速度沿键线捕获裂纹的启动。另外，该系统可用于测量相对大型标本的变形和形状，例如梁或壁，而无需安装显微镜。这些输出构成了理解层压木产品的键质量的基础。
