Abstract
The invention discloses a vacuum container for a heat-vacuum test chamber used for testing equipment mounted on a satellite or the like. A body of the vacuum container comprises an outer layer intended for mechanical reinforcement, an intermediate layer (main body) formed of a fiber-reinforced epoxy resin and intended to suppress the possibility of decomposed gas generation as much as possible, and an inner layer (voidless layer) formed inside the intermediate layer.
Claims5
A vacuum container which is highly permeable to electromagnetic waves for simulating a thermal environment and a vacuum environment in space of about 10.sup.-10 Torr, said container comprising walls having;
- an inner voidless layer consisting of epoxy resin layers and glass film layers which are alternately laminated;
- an outer layer of a thermosetting resin fiber reinforced plastic, the thermosetting resin of said outer layer being different from the epoxy resin of said inner voidless layer;
- a core layer disposed between said inner voidless and said outer layers, said core layer consisting of a low gas emission layer of epoxy resin fiber reinforced plastic;
- and
- said inner voidless, outer and core layers being adhered to one another to form a unitary structure.
