New plant-based composite is 'tough as bone and hard as aluminium'
Looking to develop a composite with high CNC content that could be shaped into strong, durable forms, they mixed a solution of synthetic polymer with commercially available CNC powder in a ratio that would create a gel with a consistency that could either be fed through the nozzle of a 3D printer or poured into a mould for casting. An ultrasonic probe was used to break up any clumps of cellulose in the gel.
