项目摘要
This project uses new 3D printing and laser etching technologies to simulate and model the effect of different droplet arrays on the bond strength between strand adherends. The difficulty with a very heterogeneous material like wood is the high coefficient of variation in strength and toughness measurements requires a large number of samples to be tested. A metal substrate would meet the requirements of a uniform, homogeneous material. Part 1 uses 3D printing to deposit `adhesive' droplets in the form of hot melt glue of fixed shape and size onto a uniform surface, i.e. aluminium plates. Droplets can be pre-printed onto one or both of the plates and bonds formed by heating them on a hot plate until the adhesive melts and then letting them cool to room temperature. The strength and toughness of the bonds will be measured and related to the droplet size and spacing, and optimal target distributions identified. These will then be tested on the non-uniform wood-resin adhesive (both hot melt and a thermoset) system of strand-based composites to validate the model. Part 2 will use laser etching to produce wooden adherends with raised bonding surfaces of controlled size and spacing. Adhesive droplet size dispersion at the interface between two wood adherends and the strength of that interface has been examined in the past by Kamke et al. (1996), Conrad et al. (2003) and Smith (2003), but the close control over droplet size and placement was limited. Smith (2005) was able to have some control over the size of the resin droplets that were printed onto a strand surface using the modified flexographic printing technique but the range of droplet sizes that could be reproducibly deposited was small. The 3D printer does not have this limitation and that should permit a much wider range of droplet sizes to be examined quickly and easily. The range of droplet sizes and inter-droplet spacing on wood strands in an industrial blender is large and with this new approach the droplet size and spacing can be carefully controlled. This will permit distributions from simple, monodisperse droplet size distributions where every droplet has the same size and distance from its neighbor to complex, random distributions that mimic those occurring in an industrial blender to be created. The next step in this process will be to bond adherends with the same or different droplet arrays together and measure the strength and fracture toughness of those bonds. Practical means of modifying the current lab spray system to produce optimal resin distributions will also be investigated. It is expected that the difference in bond strength obtained for the model bond samples and those coated in the lab-scale blender will define how much additional strength could be obtained by depositing the resin more effectively.
该项目使用新的3D打印和激光蚀刻技术来模拟和建模不同液滴阵列对链粘附体之间粘合强度的影响。对于像木材这样非常不均匀的材料,困难在于强度和韧性测量的变异系数很高,需要测试大量的样品。金属基底将满足均匀、均质材料的要求。第1部分使用3D打印将固定形状和尺寸的热熔胶形式的存款“粘合剂”液滴沉积到均匀的表面上,即铝板上。液滴可以预先印刷到一个或两个板上,并且通过在热板上加热它们直到粘合剂熔化并且然后使它们冷却到室温来形成粘结。将测量粘合剂的强度和韧性,并将其与液滴尺寸和间距以及确定的最佳目标分布联系起来。然后将在绳基复合材料的非均匀木材树脂粘合剂(热熔胶和热固性胶)系统上进行测试以验证模型。第2部分将使用激光蚀刻来生产具有受控尺寸和间距的凸起粘合表面的木质被粘物。Kamke等人(1996年)、Conrad等人(2003年)和Smith(2003年)过去曾研究过两种木材被粘物之间界面处的胶粘剂液滴尺寸分散和该界面的强度,但对液滴尺寸和位置的严密控制是有限的。Smith(2005)能够对使用改进的柔性版印刷技术印刷到股线表面上的树脂液滴的尺寸进行一些控制,但是可以重复沉积的液滴尺寸范围很小。3D打印机没有这种限制,这应该允许更广泛的液滴尺寸范围被快速轻松地检查。在工业混合器中的木片上的液滴尺寸和液滴间间距的范围很大,并且利用这种新方法,可以仔细地控制液滴尺寸和间距。这将允许从简单的单分散液滴尺寸分布(其中每个液滴具有相同的尺寸和与其相邻液滴的距离)到复杂的随机分布的分布,所述复杂的随机分布模拟在待创建的工业混合器中发生的那些分布。该过程的下一步将是将具有相同或不同液滴阵列的粘附体粘合在一起,并测量这些粘合的强度和断裂韧性。还将研究修改当前实验室喷涂系统以产生最佳树脂分布的实用方法。预计模型粘合样品和实验室规模混合器中涂覆的样品获得的粘合强度差异将确定通过更有效地沉积树脂可以获得多少额外强度。
