IF ROCKET OR MISSILE designers were asked to choose one specific property of engineering materials they would like to have improved, the largest percentage would undoubtedly select strength at high temperature.
In addition to retaining strength at high temperatures, missile materials must be resistant to erosion and ablation. Missile structures must also be satisfactory when subjected to aerodynamic and acceleration loads, high stresses of vibration, and thermal shock. The need for low-density, easily fabricated, heat-resistant materials has resulted in a continuing search for more effective combinations of known materials, as well as the development of new materials.
This paper discusses some interesting results obtained in studies of composite materials that might be used for rocket or missile construction. The studies were conducted at Cornell Aeronautical Laboratory under Contract AF33(616)-2926, DA-30-115-ORD-543, AF33(616)-5683, and at Forest Products Laboratory under Contract DO-33(616)-58-l.*
