Abstract
The results of recent work accomplished under a NASA Johnson Space Center contract to develop an advanced composite geodetic beam and beam fabrication machine for the on-orbit construction of large space structures are given in this paper. Testing to determine mechanical, physical, thermal and electrical property characteristics of a near thermally inert advanced composite material for fabrication of geodetic structures is described and results are presented. Development testing of full-scale segments of geodetic structures fabricated with this material is discussed, along with results of a test to demonstrate structural feasibility of the cylindrical geodetic beam's end attachment design. Future tests of a long geodetic beam with conical end attachments are described. These latter tests are to verify the ability of geodetic structures to withstand mechanical and thermal loading environments of space.
