Ceramicx developed equipment as part of this program to facilitate the removal of wind-screens from cars. Infrared heat was put through the laminate glass and used to activate microspheres in the adhesive. The microspheres grew to 200 times their size breaking the adhesive allowing the windscreen to be removed without breaking. The reset of the program is described below and pictures of the Ceramicx delivery are also included.
Ecological and Economical Development of Innovative Strategy and Process for Clean Maintenance, Dismantling and Further Recycling of Vehicle Parts
This project is about the eco-conception of automobiles by using adhesive joining technologies, which include active systems providing for further easy dismantling of bonded parts, at the end of a vehicle’s life or at a maintenance stage, and finding the technologies for activating these systems.
ECODISM - A New concept for an easy dismantling of structural bonded joints in auto elv and repair
To achieve the objectives of the End of Life Vehicle directive (ELV), the automotive industry and its suppliers need to come together at the design stage of the next generation of vehicles, and develop innovative processes and methodologies that will be used for maintenance, dismantling and recycling of car elements.
Today, the automotive industry suffers from a lack of solutions that could combine cost-effectiveness, speed, low energy consumption and selectivity for maintenance with the dismantling and recycling of materials, such as plastic, composite, glazing, metals and aluminium parts, which are being used more and more.
The objective of the ECODISM project is to provide ecologic and economic processes to the automotive industry to overcome these difficulties and improve its competitiveness. This will be done through the integration of active systems within adhesives that are expandable when exposing them to an external energy source. To develop processes for debonding operations, the partners will focus their efforts on:
- specifications of a wide range of active systems, type, temperature sensitivity range and coating preventing degradation
- a range and type of suitable energy sources, infrared, UV and electrical
- the technological results of the experiments and the best options for each interface
- a computer mathematical model identifying the most suitable microspheres with the trigger options to match the adhesive and materials to be bonded and debonded
- a computer mathematical model identifying the most suitable active systems with the trigger options for the application of curing to match the adhesive and the materials to be bonded
- processes and methods to use these materials for debonding operations during maintenance and dismantling operations.
- The consortium gathers 12 partners from six EU countries and Switzerland, and includes three high-tech SMEs. The consortium is representative of the European automotive industry (carmakers, suppliers for glazing, plastic composites, etc.).
Description of work
There are nine work packages merged into four main themes:
- Materials to bond (for example: glazing to painted metal sheet, composites to composites, glazing to plastics, aluminium to aluminium)
- Application methods of adhesives
- Dismantling specifications, dismantling protocols and life cycle assessment (LCA)
Adhesives and active systems:
- Integration of active systems within adhesive (thermo-expandable microspheres, blowing agents, etc.)
- Formulation of adhesives
Assembly line compatibility:
- Application of adhesives on concrete examples
- Tests on application methods
