POLYMER NANOPARTICLES FOR CONTROLLING PERMEABILITY AND FIBER VOLUME FRACTION IN COMPOSITES |
摘要 |
A fiber tow may include a plurality of reinforcing filaments each having a filament cross-sectional width. At least a portion of the polymer nanoparticles may be coupled to at least one of the reinforcing filaments and/or to other polymer nanoparticles. The polymer nanoparticles may have a particle cross-sectional width that is less than the reinforcing filament cross-sectional width. The polymer nanoparticles may provide a local filament spacing between the reinforcing filaments to reduce or avoid direct contact between reinforcing filaments, to allow for resin flow between the filaments, and/or to meet fiber volume fraction requirements. |
