IMPROVED PROCESSING OF POLYMER MATRIX COMPOSITES |
摘要 |
Systems and methods for the reduction of volatile component content from shaped prepregs and prepreg layups and the layups and composites formed therefrom are disclosed. One or more shaped prepregs or prepreg layups are placed within an enclosure and a flow of a non-condensing gas is introduced adjacent at least one surface of the shaped prepregs or prepreg layups, accelerating the rate and/or the completeness of removal of volatile components from the shaped prepregs or prepreg layups. The shaped prepregs or prepreg layups may be further subjected to heat, vacuum, and external pressure to facilitate removal of the volatile components. Shaped prepregs and prepreg layups with volatiles reduced in this manner may be further consolidated with heat, external pressure and/or vacuum. Beneficially, reduced matrix bleed and reduced fiber movement may be achieved during processing, reducing manufacturing time and improving part quality. |
