/ 19982 Effect of Hot -melt Film Impregnation on Mechanical Properties of Composite ( ) Liu DongxunOuyang huang ( Institute of Aeronautical Materials, Beijing) [ ] 32 34/ G 803PV , [ Abstract ] It has been discussed that hot-melt film impregnating G 803PV with 3234 resin affected the mechanical properties of the composite, flexural strength , flexural modulus and in- terlaminar shear strength, the retention of them . It has been show n that the hot w et resistance - . of the composite w as improved by using the method of hot melt film impregnation Keywords hot -melt film methodprepreg composite mechanical properties 1 California Graphit e Machines Inc. , , 2. 3 , , 2 / min , , 12 55 , 1. 5h , 98 , , 123 0 . 5MPa , , 2. 4 , 2. 4 . 148h / , , , 10 55 48h 1055 24h 2. 4 . 2 2 70% 70 100 0 h 2 . 1 3 234 ; 3 G803PV 5 T 30 0-30 00-40 B 2 . 2 3. 1 2 . 2. 1 1 ( a ) , , 10 ( b ) , , 0. 37% , 0 . 9%
