circles摘要：This paper describes the analys performed to determine why nominally flat composite isogrid panels designed for the Clementine I satellite were warping during the autoclave cure cycle. Analytical models indicated that the largest factor was the mismatch in the coefficient of thermal expansion of diff高帽子
nbjerent parts of the tooling. The next most important factor was the coefficient of thermal expansion mismatch between the skin and rib materials of the composite isogrid itlf. A new tooling design eliminated the first factor, producing a rib-only panel with no warping. An analytical model was developed, which predicted that warping caud by the rib/skin mismatch would be 3.31 mm over a length of 147.32 cm. A panel with the skin was manufactured and found to have a warp of 3.80 mm. Further improvements in producing flat panels
