PA+GF is one of the best solutions for the selection of high-end automotive engine covers. PA+GF has excellent high temperature resistance, aging resistance and good mechanical properties, chemical stability, alcohol and hydrolysis resistance, but poor fluidity and difficult injection molding. In order to increase its fluidity, it must be modified.
Such as: Audi's high-flow A1G6-HR, with excellent fluidity and mechanical properties, fluidity increased by nearly 60%, production cycle shortened by 15%-30%, and the parts are light, thin, and reduced in thickness. Up to 20%.
Glass fiber reinforced nylon for Audi engine cover
The hood has high requirements on the thermal aging mechanical properties of the material. The materials applied to the hood must be studied in terms of long-term thermal aging mechanical properties.
The PA6-GF30 material was subjected to a heat aging test at 150 ° C for 2,500 hours. The results of the heat aging test showed that the tensile strength retention rate of the material was above 80%, and the notched impact strength retention rate was above 65%. Heat aging performance. Therefore, PA-30GF material is suitable for the engine cover.
