Abstract : The objective of this program was to develop manufacturing methods and technology for producing glass reinforced plastic, ballistically tolerant flight control components with a high degree of reliability while utilizing low-cost fabrication techniques. This objective was achieved through development of component designs to obtain simplicity and ease of manufacture. Maximum use was made of commercially available, finished material forms which required a minimum of additional processing. Matched die molding processes were developed which allowed rapid manufacture of parts to final net dimensions. Assembly techniques were developed which utilized adhesive bonding in precision fixtures and allowed a high degree of reproducibility and reliability of the finished component. Ten complete sets of components, consisting of a quadrant and a connecting link, were prepared for an extensive verification testing program which included mechanical, environmental, and ballistic impact testing. Material, process, fabrication, and quality control specifications were prepared.
