High quality clear coatings for veneer-faced aerospace panels

公务机的内部装饰通常会通过使用复合面板和具有高度“图形”的木制饰面的橱柜来增加吸引力，这些饰面非常漂亮。这些面板的美感通过抛光产生高反射镜面光滑表面的透明涂层进一步增强。然而，表面光洁度和反射率可能会受到下面木材的膨胀的影响，这是对射流内部大气条件变化的响应。木材基材的膨胀会传递给涂层，从而产生明显的波纹。对于制造公务机的公司来说，贴面板和橱柜上的涂层泛起涟漪是一个严重的问题，因为它会引起客户的不满，并导致高昂的成本，从公务机内部拆除面板和家具，然后再进行返工以恢复到原来的状态。这个项目寻求解决这个问题的办法。我们将修改贴面的分子结构，以抑制其对水分的尺寸反应。我们将制造贴面的透明涂层航空航天面板，其中包含改性贴面，对面板进行水分循环测试，模拟公务机内部的波动环境条件，并将其性能与目前最先进的面板进行比较。我们预计会有重大改进。该项目将帮助庞巴迪保持竞争力，这一点非常重要，因为庞巴迪是航空航天领域最重要的公司，为加拿大人提供了超过21.1万个优质工作岗位，每年为加拿大经济创造了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.
