Locking Mechanism for a Flexible Composite Hinge

Abstract
Content

Composites have excellent strength characteristics, are lightweight, and are increasingly being used in space applications. However, they are highly inflexible and require hinged joints when used as deployable structures. This is a challenge for CubeSats/SmallSats, as the hinges and actuation mechanisms get very small and require multiple custom precision parts. A method of impregnating carbon fibers with a silicone matrix has been developed, which makes the composite flexible. This also makes it self-deploying, as the strain energy in the fibers will cause it to straighten. Unfortunately, a purely flexible beam does not have the required rigidity to maintain dimensions accuracy, as it can sag.
