摘要:
Prepregs, composites and articles comprising expandable graphite materials dispersed in a thermoplastic layer are described. In some instances, articles that can be used in an as- produced state may provide a desired sound absorption coefficient or a desired flame spread index, e.g., less than or equal to 25 as tested by ASTM E84 dated 2009. Methods of producing the articles are also described.
摘要:
La présente invention porte sur un système étanche d'isolation acoustique sous forme de plaques destiné à être positionné sur un support et directement sous carrelage. Ce système est constitué d'une plaque isolante couplée à une partie étanche, ladite plaque isolante plaque isolante étant composée d'une ou plusieurs couches solidaires les unes des autres. Un procédé de fabrication d'un sol carrelé mettant en œuvre ledit système est également un objet de la présente invention.
摘要:
A burnthrough protection system including a fire protection laminate and a foam insulation material, wherein the fire protection laminate includes a fire barrier layer and a buffer layer, the buffer layer being disposed between the fire-barrier layer and the foam insulation material, wherein the buffer layer is adapted to prevent adhesion between the fire barrier layer and the foam insulation at elevated temperature. The burnthrough protection system may be capable of passing the flame propagation and burnthrough resistance test protocols of 14 C.F.R. § 25.856(a) and (b), Appendix F, Parts VI and VII. Also, an aircraft including an exterior skin, an interior liner, and the burnthrough protection system disposed between the exterior skin and the interior liner.
