One-piece seamless enclosure and methods of making it |
摘要 |
Methods and means for providing a one-piece seamless enclosure include a plurality of panels each having a foam core surrounded by a fiber reinforced cloth or woven material. The panels are joined inside of an outer mold. An inner inflatable mold is inserted into the area between the panels and pressurized. Resin is pumped into the cavity between the inner and outer molds and then cured. The molds are removed and a one piece seamless enclosure or shelter is provided.
