Abstract:
The objective of the project is to expand the successful developmentof DWG (Grfiber/Al) end fitting and integrate the continuing work into a comprehensive
program designed to achieve a thermally stable truss structure using DWG end fittings
and tubes. Zero CTE end-fitting material, fabricability of DWG into complex geometry,
and end-fitting design concepts have been accomplished. The major objective is to
establish the design requirement for fittings, tubes and joints in terms of CTE,
load capability and weight; to optimize DWG materials used for fittings and tubes
over the intended temperature spectrum. The program will also consider innovative
DWG heat pipe for temperature control; cored panel with DWG face sheet; DWG-angle
structural members; and metal-matrix composite weldment. It is anticipated that
uses of DWG in the steady will spawn applications of this stiff, strong, low-density
MMC in aerospace structure, missile components, medical apparatus, and instrumentation.
