    • 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.
    • 公开了用于从成形的预浸料坯和预浸料叠层以及由其形成的叠层和复合材料来降低挥发性组分含量的系统和方法。 将一个或多个成形的预浸料坯或预浸料叠层放置在外壳内,并且在成形的预浸料坯或预浸料叠层的至少一个表面附近引入非冷凝气体流,从而加速挥发性组分的除去速率和/或完整性 从成型的预浸料或预浸料上层。 成型的预浸料坯或预浸料叠层可以进一步经受加热,真空和外部压力以便于除去挥发性组分。 以这种方式减少的具有挥发物的成型预浸料坯和预浸料叠层可以进一步加热,外部压力和/或真空固化。 有利的是,在加工过程中可以实现减少的基体渗出和减少的纤维移动,减少制造时间并提高零件质量。
