Abstract:

The aggregate grading study on particulatereinforced composite (resin and quartz plate composite ) were studied with test.The results show that the prior way of aggregate gradation  can be obtained with right ratio of large particle quartz sand and small particle quartz plate，which can lower the quantity of resin from 20~25% to 12~14%，reduce the cost，improve the economy profits，and ensue not to lower bend strength of winding layer.
