Aggregate Grading and Mechanical Property Study on Particulate-Reinforced Composite

The aggregate gradation and mechanical property of particle reinforced composite (resin and quartz sand composite ) were studied with test, the results show that: The more optimal scheme of aggregate gradation can be obtained with right ratio of larger particle quartz sand and small particle quartz plate , which can make the gradation resin content from the original 20% ~ 25% reduced to 12% ~ 14%, so as to reduce the cost and improve the economic benefit and guarantee bending strength of winding layer not decrease in the meantime
