L'invention concerne un dispositif d'absorption d'énergie cinétique pour élément de structure d'aéronef susceptible d'être soumis à un impact dynamique, comportant: - une enveloppe externe (21) en matériau composite tressé apte à conserver, après impact, une intégrité, - un cœur en mousse (22), contenu dans l'enveloppe externe et apte à remplir au moins partiellement ladite enveloppe externe, ledit cœur en mousse étant apte à absorber au moins partiellement l'énergie cinétique générée par l'impact, et - des éléments de renfort comportant au moins une préforme en fibres composites sèches (30) intégrée dans le cœur en mousse pour dissiper, en association avec le cœur en mousse, l'énergie cinétique générée par l'impact. L'invention concerne également un procédé d'intégration de ce dispositif d'absorption d'énergie cinétique.
摘要:
A fast cure epoxy resin system is provided that upon curing has a Tg no greater than 140°C and a Phase angle below 20° at a temperature of 140°C or below, and prepregs and mouldings based on the system. The resin formulation matches the reactivity of the resin to the amount of curative and hardener employed.

摘要:
ie Erfindung betrifft ein Paneel zur Verkleidung einer Decke oder Wand in einer Kabine, insbesondere der Kabine eines Passagierflugzeugs, bei dem eine Platte (3) beidseitig mit einer Deckschicht (2a, 4a) laminiert ist, wobei die Platte (3) eine aus einer Vielzahl von Zellwänden (7) gebildete Wabenstruktur aufweist. Zur Verbesserung der geräuschdämmenden Eigenschaften wird erfindungsgemäß vorgeschlagen, dass die Zellwände (7) in einem vorgegebenen Bereich (B) der Platte (3) abschnittsweise gewölbt oder geknickt sind.
摘要:
The present disclosure encompasses three-dimensional articles comprising flexible- composite materials and methods of manufacturing said three-dimensional articles. More particularly, the present system relates to methods for manufacturing seamless three- dimensional-shaped articles usable for such finished products as airbags/inflatable structures, bags, shoes, and similar three-dimensional products. A preferred manufacturing process combines composite molding methods with specific precursor materials to form fiber- reinforced continuous shaped articles that are flexible and collapsible.
摘要:
A powder resin layered nonwoven material and a method of construction thereof are provided. The method includes forming a nonwoven web; applying a powder resin material on the nonwoven web to form a coated portion of the nonwoven web; and cross-lapping the nonwoven web to sandwich separate powder resin layers of the powder resin material between layers of the nonwoven web.
