Associated Project 8 (AP 8)

BIOPROFILE: (CO-)EXTRUDED PROFILES FROM BIOPLASTICS REINFORCED WITH PLANT RESIDUES 

The goal of the research project is the production of various plant-residues bioplastic reinforced profiles, ranging from window and facade profiles with good thermal insulation and good flame retardant properties, up to semi-elastic flat profiles in form of plates with potential of being used as core material in fabrication of structural sandwich panels. All profiles are made by extrusion and co-extrusion from disintegrated wheat straw fibres and other natural fibres. The aim is to propose an alternative biomaterial which could replace conventional PVC profiles used for windows productions, as well as aluminum, wood and Wood-Polymer Composites (WPC) ones. Products made from renewable biomaterials are becoming increasingly important due to climate change and the noticeable shortage of fossil raw materials. The co-extrusion process is to be used primarily to produce bio window profiles, with the core consisting of plant/wood waste-based natural fibre-reinforced bioplastics and the outer layer/cover of plant waste-reinforced bio plastics and/or veneer. Within the framework of the physical and mechanical properties required for the component, the aim is to achieve the highest possible degree of fibre filling. The product itself should consist of up to 100% renewable raw materials. In the course of the project numerous semi-product samples and mock-ups demonstrating their potential application were developed.
