ABSTRACT:
A vacuum-tight, nonmetallic hollow article is fabricated from composite material of fibers in a resin matrix. The article has a closed end, and is laid up from sheets of the composite material and end pieces to form the closed end. The layers are mechanically worked and debulked repeatedly during layup between the addition of successive layers, to remove irregularities that can cause vacuum leaks. The joints between the sheets applied to the sidewalls and the end pieces are mechanically worked to effect a vacuum-tight seal, and the joints are staggered as between succeeding layers for strength and integrity. The laid up and debulked piece is finally cured.
