PREPREGS AND CARBON FIBER-REINFORCED COMPOSITE MATERIAL |
摘要 |
<p>A prepreg comprising noncircular cross-section carbon fibers and a matrix resin having a flexural elastic modulus of 2.7 GPa or more and a water absorption of 3.4 % or less under hot-wet conditions after curing; and another prepreg comprising carbon fibers and a matrix resin having an open-hole compression strength under hot-wet conditions and a compression strength after impact under room-temperature conditions of a quasi-isotropic material after curing of each 275 MPa or more. Carbon fiber-reinforced composite materials produced by curing these prepregs are excellent in open-hole compression strength under hot-wet conditions and in compression strength after impact, and can be suitably used especially as an aircraft primary structure material. <IMAGE></p> |
