Abstract
In order to reduce the cost and improve the performance of potash feldspar (PF)/unsaturated polyester (UP) composites, the effects of potash feldspar loading towards mechanical, physical, and morphology of UP/PF composites were studied. In this study, the UP/PF composites with varies ratio of potash feldspar (2.50, 5.00, 7.50, and 10.00 phr) were prepared by using casting technique. The results showed that the potash feldspar can improve mechanical properties of UP/PF composites effectively. For the best tensile and flexural properties of UP/PFF composites, the appropriate amount of potash feldspar was 5.00 phr. The potash feldspar amount for preparation of UP/PFF composites should be based on the processing requirements and the demands for different working conditions.
