摘要： Thermoplastic honeycomb capable of formation by expansion of a compacted ribbon stack and of repeated dips in resin solution to form densified honeycomb panels is prepared by impregnating a fiber web with a thermoplastic material which has a soluble form and an insoluble form, and is readily converted from the former to the latter. Poly(amide-imide)s are an example of a suitable resin. The invention is particularly useful in forming compacted ribbon stacks of resin-impregnated glass fiber, expanding the stacks at an elevated temperature to a partial expansion sufficient to expose the cell interiors, then dipping the partially expanded stacks in resin solution, removing the solvent from the resulting film and curing the film, then expanding the stacks further at an elevated temperature to their full expansion, following by further dips to the final desired density.
摘要翻译：通过膨胀压实带堆叠形成的热塑性蜂窝体和树脂溶液中的重复浸渍以形成致密蜂窝板的热塑性蜂窝体通过用具有可溶形式和不溶性形式的热塑性材料浸渍纤维网来制备，并且容易地从前者为后者。聚（酰胺 - 酰亚胺）是合适树脂的实例。本发明特别可用于形成压实的树脂浸渍的玻璃纤维的带状堆叠，将堆叠在升高的温度下膨胀至足以暴露电池内部的部分膨胀，然后将部分膨胀的叠层浸入树脂溶液中，从然后使薄膜固化，然后在升高的温度下将叠层进一步膨胀至其完全膨胀，然后进一步下降至最终期望的密度。

摘要： Honeycomb fabricated of non-crosslinked polymer is prepared by impregnating a fiber web with a linear prepolymer which is soluble in an organic solvent, and which is readily converted by thermal curing in the absence of a crosslinking agent to an insoluble form with a glass transition temperature exceeding 200 DEG C, preferably exceeding 250 DEG C. The preferred prepolymer is the product of diaminodiphenylsulfone and trimellitic anhydride, and forms a poly(amide-imide) upon cure. A process for forming the impregnated honeycomb is also disclosed, which involves impregnating ribbons or sheets, forming them into stacks bonded together at node lines, expanding the stacks into honeycomb structures, and heat soaking the expanded structures to cure the resin and stabilize the structure.
摘要翻译：通过用可溶于有机溶剂的线性预聚物浸渍纤维网来制备由非交联聚合物制成的蜂窝体，并且在不存在交联剂的情况下通过热固化容易地转化为具有玻璃化转变温度的不溶形式超过200℃，优选超过250℃。优选的预聚物是二氨基二苯基砜和偏苯三酸酐的产物，并且在固化时形成聚（酰胺 - 酰亚胺）。还公开了一种用于形成浸渍蜂窝体的方法，其包括浸渍条带或片材，将其形成为在节点线处结合在一起的堆叠，将堆叠扩展成蜂窝结构，并且热膨胀膨胀结构以固化树脂并稳定结构。

摘要： Un nid d'abeilles en polymère non réticulé est préparé en imprégnant une bande de fibre d'un prépolymère linéaire soluble dans un solvant organique, et qui est facilement transformée par polymérisation thermique en l'absence d'un agent de réticulation en une forme insoluble dont la température de transition du verre dépasse 200 °C, de préférence supérieure à 250 °C. Le prépolymère préféré est le produit de diaminodiphénylsulfone et d'anhydride trimellitique et forme un poly(amide-imide) après polymérisation. On décrit également un procédé de formation du nid d'abeille imprégné consistant à imprégner des bandes ou des feuilles, à en former des empilements collés aux lignes nodales, à faire dilater les empilements pour obtenir des structures en nid d'abeilles, et à traiter thermiquement les structures expansées pour polymériser la résine et stabiliser la structure.
