Noise reduction in different applications by use of recycled composite materials

Objective



Noise Reduction in Different Applications by Use of Recycled Composite Materials The proposed project is to develop a totally new concept for acoustical applications using recycled composite material of polyester and glass fibre. By studying applications suggested by the industrial partners, such as large engine casing cladding panels, chemical resistant panels, and noise shields at roads, laminate containing up to 50% by volume of ground composite particles will be produced. The market potential within EC is estimated to 585.5 MECU for these applications. Many composite manufacturers produce a lot of waste, normally disposed in landfills to a constantly increasing cost. By using waste material, converted into useful ground recycled material, new products with good acoustical properties can be developed . The technical risk is high but well considered and justified by the economical and environmental benefits. The wide competence of the consortium gives a unique opportunity to investigate all aspects of the developing process. A successful project will result in new markets and products for SMEs leading to extended business and increasing number of employees. The studied applications are acoustically different and therefore a variety of solutions are required. Test panels of different thicknesses and material composition will be manufactured and the acoustical/dynamical properties measured. The acoustical properties transmission, absorption and reflection of noise (20-20,000 Hz) will be measured in a sound proof laboratory. The dynamical properties, damping and natural frequencies, will be measured for the same frequency interval. Tools for analysing and predicting dynamic and acoustic properties will be developed and evaluated against experimental results. Manufacturing technique and equipment will be developed for using recycled materials. It is important that the developed laminates are of industrial interest with acceptable costs, satisfying mechanical properties, good reduction of noise and a manufacturing technique which is as simple as possible. Environmental considerations are also important in the choice of materials and manufacturing techniques.
