Ett VINNOVA-sponsrat projekt

Project description:

The BIOAUTO project describes the set-up and organization of two parallel demonstrators aiming to produce 3D composite prototypes made from renewable resource based fibres, matrices and surface textiles for use in the automotive industry. The constituent materials are reinforcement cellulose fibres; sisal, flax, hemp, wood fibres and a biopolymer matrix; cellulose ester. Surface materials are based on PLA, viscose, cotton, wool, flax etc. The main objective of this work is to explore the possibility of industrially viable applications of renewable resource based materials for the manufacture of a limited and pre-selected number of automotive interior components. The prime considerations for the project are the development of suitable basic materials and appropriate process technologies for achieving the necessary product functionalities fulfilling the technical specifications laid by the automotive manufacturers. The project is sponsored by VINNOVA (Swedish Agency for Innovation Systems) and started mid 2003 and will run for 2,5 years.

Demonstrator A is designed to produce 3D high-density prototypes by using extrusion and injection moulding techniques for applications such as interior panels and covers. Demonstrator B is designed to produce 3D low-density prototypes using web-making techniques such as carding, air-laying, needle-punching followed by compression moulding. These prototypes will find applications as car components where thermal and acoustical insulation is of high priority.

The research activities include development of cellulose fibres with suitable surface and bulk properties, development of suitable biopolymer based matrices and suitable process technology. Special attention is given to enhancement of natural fibre- bio-matrix adhesion, drastic reduction in the moisture sensitivity of cellulose fibres and biopolymers, significant resistance in thermal sensitivity of bio-composites products etc.
