5 Often, Designs are not Optimized for the Use of Composites Materials A&D Industry Observations 6 "Overdesignedcomposites cannot compete with lowercost, established material systems." "The relative inexperience with composite materials compared to their metallic counterparts often necessitates either overdesign of components or more frequent inspections and monitoring." OVERDESIGN "Overdesignto address uncertainty negates the advantages of composites" Page 6
