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.

胶粘复合技术是保持加拿大木制品生产商竞争力的驱动力之一，它依赖于生产高性能和耐用的工程木制品（ewp）。层压EWP产品的粘合质量决定了其使用性能，必须对其进行准确的评估。申请设备为3D立体显微镜数字图像相关系统，是为满足申请人的研究需求而专门设计的。该系统包含一台立体显微镜和两台数码相机，并配有用于3D和2D图像分析的软件。该系统可以以每秒150帧以上的速度捕捉到沿粘合线产生裂纹的过程。此外，该系统可用于测量相对较大的试样，如梁或墙的变形和形状，而无需安装显微镜。这些结果构成了理解层压木制品粘合质量的基础。
