Study of the Physical Property Expression Factors of Direct Molding and Construction of GF Dispersibility Index

Abstract

To reduce material costs, a direct molding method that can reduce the cost of resin and fiber compounding by mixing resin and fiber and by molding using an injection molding machine has been actively researched. However, a glass fiber bundle size of visible size that remains in the molded product is a factor in the loss of strength due to the insufficient kneading. Elucidating the mechanism of physical property expression is necessary to achieve the target physical properties of the molded products.
