Wrapped Tow Reinforced truss concept2
Truss geometry Composite materials Winding process
• Move material away from axis of bending
• Members experience primarily axial loading
• Anisotropy can be tailored to maximise efficiency
• Low-cost constituents
• Repeatable
• Highly level of automation
Manufacturing3
• Tow twisting investigation“Flat” “Twisted”
• Concept scaling
• Complex geometries• Non-prismatic
• Curved?
Analysis4
• Trusses modelled using matrix structural analysis techniques• Beam elements for each member
• Joint members allow:• Node displacement
• Introduction of bending moments
Future Work5
• Strength predictions
• Further concept scaling
• Optimisation
• Applications
