WrapToR composite truss structures Chris Hunt, Michael Wisnom, Ben Woods CDT Conference 2019 16 th April 2019
2 Wrap ped To w R einforced truss concept Winding process Truss geometry Composite materials • • Anisotropy can be tailored to • Move material away from Low-cost constituents maximise efficiency axis of bending • Repeatable • Members experience primarily axial loading • Highly level of automation
3 Manufacturing • Tow twisting investigation • Concept scaling “Flat” “Twisted” • Complex geometries • Non-prismatic • Curved?
4 Analysis • Trusses modelled using matrix structural analysis techniques • Beam elements for each member • Joint members allow: • Node displacement • Introduction of bending moments
5 Future Work • Strength predictions • Further concept scaling • Optimisation • Applications
