SSUCHY aims at exploiting the intrinsic and differentiating properties of plant fibres and biopolymers derived from lignocellulosic feedstock to develop fully bio-based composites with improved functionalities. The main driver behind this project is not only to substitute conventional fossil-based materials with more sustainable bio-based ones but also to achieve improved functionalities that surpasses those of fossil-based ones. Enhanced functionalities are, in addition to load-bearing resistance and weight reduction of structures, enhanced durability, vibration damping, vibro-acoustic control and fire retardancy while retaining an essentially recyclable and, for certain applications, biodegradable character. Such developments would provide to the composite industry a significant value and functions added products with high socio-economic impacts and minimized environmental impact. It will create opportunities to expand market applications for bio-based composites to semi-structural and functional applications in transportation along with new opportunities in high value niches.
