摘要: Processes for producing near net-shape panels and panels formed thereby. The processes include forming a preform to comprise a stack of multiple plies that contain an uncured expandable foam material. The preform has regions that differ from each other by the number and/or volume of the plies therein. The preform and its plies are then cured within a restricted volume to produce a near net-shape panel. The curing step causes the expandable foam material to expand, and the restricted volume is sized so that the number and volume of the plies within the regions of the preform cause zones within the panel to have different densities and/or thicknesses.

摘要翻译: 用于生产由此形成的近网状面板和面板的方法。 所述方法包括形成预制件以包括含有未固化的可膨胀泡沫材料的多层叠层。 预型件具有彼此不同的区域的数量和/或体积。 然后将预成型件及其层叠体在受限制的体积内固化以产生接近网状的面板。 固化步骤使可膨胀泡沫材料膨胀,并且限制体积的尺寸使得预成型体区域内的层的数量和体积使得面板内的区域具有不同的密度和/或厚度。

摘要: Polymer-based materials and processes suitable for producing panels, for example, panels for use in a fan shroud abradable seal of a turbofan engine. Such a process includes introducing constituents of an expandable foam material into a continuous forming apparatus that continuously compounds the constituents into a partially-cured compounded polymeric material, which is then continuously formed with the continuous forming apparatus to produce a continuous form having a constant cross-sectional shape transverse to a continuous forming direction of the continuous forming apparatus. A portion of the continuous form is then deformed to produce a preform, and the preform is cured within a restricted volume to cause the preform to expand and produce the panel.
