| Within this research work natural fibre reinforced composites with high natural fibre content between 70 wt.-% and 80 wt.-% and a thermoset polymer system on acrylic basis will be treated with environment-friendly sodium silicates (water glass). Water glass is applied in other fields as binder, hydrophobic system, and flame retardant system. The new matrix system will be applied by binder dispersion in a dipping process on the natural fibre mats. Processing conditions such as curing temperatures and times of this system should be comparable to those of a standard acrylic resin system. Mechanical characteristics and the water absorption of manufactured components were examined. The effectiveness of the flame retar-dant effect of water glass was also tested. This paper describes the first results of the research project.
