High quality clear coatings for veneer-faced aerospace panels

商务喷气式飞机的内饰经常因为复合面板和橱柜的装饰性使用而显得更具吸引力，这些面板和橱柜的特点是非常漂亮的木质贴面。这些面板的美观由透明涂层进一步增强，这些涂层经过抛光，以产生高度反射的镜面光滑表面。然而，表面抛光的平整度和反射率可能会受到下面木材膨胀的影响，以响应喷气式飞机内部大气条件的变化。木材基材的膨胀通过涂层传递，从而产生明显的波纹。对于制造商务机的公司来说，贴面面板和机柜上的涂层涟漪是一个严重的问题，因为这会导致客户的不满，并导致从商务机内部拆除面板和家具的成本高昂，以及随后的返工以将它们恢复到原来的状态。这个项目寻求解决这个问题的方法。我们将修改单板的分子结构，以抑制其对水分的空间响应。我们将制造单板表面、透明涂层的航空面板，其中包含改进的单板，对面板进行湿度循环测试，模拟商务机内部发生的波动环境条件，并将其性能与目前最先进的面板进行比较。我们预计会有显著的改善。该项目将帮助庞巴迪保持竞争力，这一点非常重要，因为它是航空航天行业最重要的公司，为加拿大人提供了超过211,000个优质工作岗位，每年为加拿大经济带来280亿美元的GDP。

The interiors of business jets are often given added appeal by the decorative use of composite panels and cabinetry that feature highly 'figured' wooden veneers that are exceptionally beautiful. The beauty of these panels is further enhanced by clear coatings that are polished to produce a highly reflective mirror-smooth surface. The smoothness and reflectivity of the surface finish, however, can be affected by swelling of the underlying wood in response to changes in atmospheric conditions within the interiors of jets. Swelling of the wood substrate is telegraphed through to the coating, which develops noticeable rippling. Rippling of coatings on veneered panels and cabinets is a serious issue for companies that manufacture business jets because it results in customer dissatisfaction and costly removal of panels and furnishings from the interior of business jets, and subsequent rework to restore them to their original condition. This project seeks a solution to this problem. We will modify the molecular structure of veneer to dampen its dimensional response to moisture. We will fabricate veneer-faced, clear coated aerospace panels that incorporate modified veneer, subject panels to moisture-cycling tests that simulate the fluctuating environmental conditions that occur in the interior of business jets, and compare their performance with that of panels that are currently state-of-the-art. We anticipate significant improvements. The project will help Bombardier remain competitive, which is very important because it is the most significant company in the aerospace sector that provides over 211,000 quality-jobs for Canadians and $28 billion annually in GDP to Canada's economy.
