The Influence of Coating on the Elastic Modulus of Basalt Filament Diaphragm Fabric

Abstract:

This paper focuses on the influences of the technologies such as curing time, curing temperature and coating on the elastic modulus of basalt filament diaphragm fabric. This paper compares the elastic modulus of basalt filament diaphragm fabric with that of glass fiber diaphragm fabric under the same fabric density, texture and coating thickness, thus discusses the feasibility of using basalt filament as cone material. In the experiment, we use CSW-03 loom to weave basalt filament diaphragm fabric and glass fiber diaphragm fabric, then we use Werner Mathis AG LTF97885 coating machine to coat them and then use 3380Instron advanced testing machine to test the elastic modulus and the breaking strength. Conclusion: The coating curing effect, the elastic modulus and the breaking strength will reach their best when the temperature is 120°C, the time is 30 minutes. When the coating thickness is 0.05mm, the elastic modulus of basalt filament diaphragm fabric will be best. So considering the elastic modulus, basalt filament diaphragm fabric is more suitable than glass fiber diaphragm fabric. The result of this paper can be used as theoretical basis for the development of basalt filament diaphragm fabric. So we can develop more materials related to basalt filament diaphragm fabric to enhance market competitiveness.
