ABSTRACT:
A tubular circular cylindrical member, an attached frustro-conical member, and attached annular stiffening rings are formed of a metal matrix composite (MMC) material such as SiC/Al. The combined cylindrical and conical structure has a tapered wall thickness which reaches a maximum value at the point nearest the attachment of the structure to its launch vehicle. The entire structure and rings are quasi-isotropic, have a homogeneous microstructure, are low in weight, high in strength and stiffness, and are thermally stable with minimum distortion due to exposure to thermal cycling.
