Design improvement of self-deployable booms made of fibre composite

What is it about?

Process of design improvement of self-deployable composite booms via virtual testing. Both static and dynamic behavior of composite hinges are simulated and newly developed anisotropic failure criterion is used to check for material failure. Hinge geometry is defined with three parameters and sensitivity is examined for a single hinge first. Selected hinge geometry is then used for a 1 m long boom designed to wrapped round a spacecraft and dynamic behavior is validated against physical experiments.

Why is it important?

This paper describes complete cycle of design improvement of self-deployable booms made of fibre composites. Prediction of material properties, application of failure criteria and simulation of both static and dynamic behavior is discuss in the paper.
