Abstract
This thesis presents experimental and finite element analysis results of eccentrically loaded carbon-fiber composite booms that can deploy solar sails. Using the collapsible tubular mast design along with the geometry from the upcoming Advance Composite Solar Sail System mission, short composite booms segments were manufactured for testing. New clamps were also designed to allow a column bending test to achieve eccentric loading. As buckling through eccentric loading has not previously seen much research, the geometry and composite layups were simplified to allow for ease of manufacturing and verification. The work presented here shows that a finite element simulation, using a new composite material model, can easily simulate the eccentric buckling of collapsible tubular mast booms. It was found that composite booms with this geometry realize two different buckling events. First, local buckles form near each set of clamps, and then a second buckling causes a loss of structural support.
