Abstract
A process for fabricating a unitized structure comprises creating a multilayer structure by applying a flame-retardant resin to a first layer and stacking, on the first layer, an intermediate layer comprising a honeycomb structure. Further, a second layer is stacked on the intermediate layer and the flame-retardant resin is applied to the second layer. The multilayer structure is then heated to a desired temperature and a pressure is applied about the multilayer structure for a predetermined process time. Moreover, the flame-retardant resin is prevented from entering spaces of the honeycomb structure. After elapse of the predetermined process time, the pressure is released, creating the unitized structure.
Claims9
A process of fabricating a unitized structure having a fire rating, the process comprising:
- obtaining an assembly, the assembly comprising:
- a first layer that is permeable to a fire-retardant resin;
- a second layer;
- and
- an intermediate layer comprising a low density, porous insulating material, wherein the intermediate layer is disposed between the first layer and the second layer;
- heating the assembly for a predetermined heating time;
- applying a vacuum to the assembly for a predetermined vacuum time, the applied vacuum being sufficient for the fire-retardant resin to penetrate the first layer but insufficient to penetrate the intermediate layer without a scrim layer;
- and
- controlling a delivery operation wherein the fire-retardant resin is applied to at least a portion of an outside of the first layer of the assembly such that upon completion of the predetermined vacuum time and the predetermined heating time, a unitized structure having a fire rating is fabricated.
