METHOD OF MAKING A LAMINATE COMPONENT AND METHOD OF REMOVING VOIDS FROM A PRE-PREG PLY AND A PRE-PREG COMPONENT |
| 摘要 |
A method of making a laminate component and method of removing voids from a pre-preg ply and pre-preg component are provided. The method of making a laminate includes laying up a plurality of pre-preg plies in a desired geometry, the plurality of pre-preg plies having a plurality of fibers and a resin. The method includes creating at least one void-reducing channel in at least one ply of the plurality of pre-preg plies, the void-reducing channel being perpendicular to a fiber orientation in the at least one ply. The void reducing channel locally re-orients the fibers adjacent to the void-reducing channel in the at least one pre-preg ply. The method includes laminating the plurality of pre-preg plies. The resin fills the at least one void-reducing channel and the laminate component has a porosity margin of about 1.5%. |

1. A method making a laminate component comprising:
laying up a plurality of pre-preg plies in a desired geometry, the plurality of pre-preg plies having a plurality of fibers and a resin; creating at least one void-reducing channel in at least one ply of the plurality of pre-preg plies, the at least one void-reducing channel being perpendicular to a fiber orientation in the at least one ply, wherein the at least one void-reducing channel locally re-orients the fiber orientation adjacent to the at least one void-reducing channel in the at least one pre-preg ply; and laminating the plurality of pre-preg plies, wherein the resin fills the at least one void-reducing channel, wherein the laminate component has a porosity margin of about 1.5%. |
