Abstract: Graphite Storable Tubular Extendable Masts (GSTEMs) are being investigated and developed for use as an extendable spacecraft boom that can be deployed and retracted on orbit. The advantages of GSTEMs over traditional metallic deployable booms include reduced thermal deformations due to reduced coefficient of thermal expansion and stronger/stiffer booms due to higher strain limit allowing thicker materials to be used. Despite the advantages of GSTEMs, much work is needed to understand and characterize their per… Show more

“…Thermal radiation in space structures leads to thermal instabilities such as thermal shock, thermally induced oscillations, and thermal bending [42]. Also, temperature has been used to change the matrix properties of the BiTSs which leads to a release of the strain energy in their stowed configurations [43].…”

“…These thin composite laminates are desirable in the field of deployable space structures for the lack of reliance on mechanical mechanisms for structure packaging and on orbit unfolding. Variations of the laminate established by AFRL have been employed in the fabrication of structural tape springs used as flexural hinges 3,4 , in storable tubular extendible masts 5 , in the SIMPLE boom 6 and in antennas 7 . The specific tape springs studied here are integrated into a structure that will be the first space flight of a thin, flexible carbon fiber laminate structure known to the authors.…”

“…A number of deployable space structure architectures have been or are currently under development, which employ thin composite laminates [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26], two of which are shown in Fig. 1 [18,19].…”
