Abstract:

A set of two each engineering panels of each specification thickness were fabricated this period. The fabrication procedure employed extensive preconditioning steps and a long stepwise molding cycle. Major steps in the preconditioning cycle involved a high vacuum conditioning of the loose stack and a long drying cycle at 225 F with the stack compressed under vacuum pressure. The molding cycle employed a long stepwise temperature rise and fall and a twenty minute dwell at maximum temperature. Resultant panels had extensive surface delaminations, surface discoloration areas and a general lack of translucency. Subscale panels were fabricated using a revised molding procedure that eliminated the high vacuum preconditioning, lowered all precondition temperatures to 180 F or less and employed a molding cycle with rapid heatup and cool down and a short dwell time.
