Abstract
This report describes a program, comparing the bird impact resistance of new as-extruded polycarbonate with polycarbonate that has undergone natural aging, artificial heat aging, fabrication heat treatments, and fabrication heat treatments with subsequent artificial heat aging. The two pound bird impacts were carried out on flat 24 inch by 24 inch monolithic specimens, mounted 45° to the horizontal. A rigid test frame incorporating a "clamped" specimen edge design was utilized. Bird impacts on the modified material resulted in a significant decrease of penetration velocity, with a corresponding change from a ductile to a brittle type failure mode
