Processing and properties characterisation of polylactide based fully biodegradable composites
This project has a goal to manufacture and characterise fully bio-degradable composite material based on polylactic acid (PLA) and wood pulp which has the potential to be used as components in the automotive industry. PLA is acting as the matrix and wood pulp as the reinforcing fibre. PLA has been c...
