HONEYCOMB CORE HAVING A HIGH COMPRESSION STRENGTH |
| 摘要 |
This invention pertains to a method of making a fiber-reinforced composite structure comprising the steps of (i) forming a paper sheet having a Gurley air resistance at least 200 seconds per 100 milliliters, the sheet comprising from 30 to 70 weight percent p-aramid fiber, (ii) depositing on both surfaces of the paper sheet a compression enhancing layer in a quantity up to 5 weight percent based on the weight of the paper, (iii) forming a honeycomb from the sheet of step (ii), and (iv) applying a matrix resin coating to the honeycomb of step (iii). |

1. A method of making a fiber-reinforced composite structure comprising the steps of:
(i) forming a paper sheet having a Gurley air resistance at least 200 seconds per 100 milliliters, the sheet comprising from 30 to 70 weight percent p-aramid fiber, (ii) depositing on both surfaces of the paper sheet a compression enhancing layer in a quantity up to 5 weight percent based on the weight of the paper, (iii) forming a honeycomb from the sheet of step (ii), and (iv) applying a matrix resin coating to the honeycomb of step (iii). |
