Scientific Case

Traditional reinforcement for fibre composites are fabricated by laying up plies of aligned fibres. Over the years, the textile technology for manufacturing complex-shaped composite structures has significantly improved, among which braiding is a promising technique to form continuous fibre reinforced composites. Braiding has the potential to produce complex near net shapes with fibre continuity at the edges. Braided composites provide many advantages over traditional laminated composites, including their higher resistance to delamination damage. However, there are more variables involved in the braiding process determining the properties of braided composites, making it comparatively difficult to correlate the damage micro-mechanics with braid microstructure. This project aims to establish the relations between macro behaviour and micro mechanisms of braided composite tubes by tracking damage evolution under torsion and correlating with braid microstructure.The 10kN open frame rig will be integrated onto Nikon Custom Bay to apply torsional load for time-lapse imaging.
