| 摘要 |
A lightweight, flexible, layered insulation composed of glass or ceramic fabric covered with a ceramic coating and overlying an insulating felt made from needled polybenzazole (PBZ) material which is preferably polybenzoxazole (PBO), and which optionally contains a poly(1,3-phenylene isophtalamide) felt material, commercially known as Nomex(TM), either combined with the PBZ felt or layered beneath the PBZ felt as a separate layer. The insulation is readily applied to a reusable launch vehicle via a silicone adhesive.
