An investigation into fibre spreading

[摘要] An investigation into the effect of fibre spreading on the physical properties of filament wound tubes has been conducted. Two custom-built spreading rigs were experimentally tested for their ability to spread a single or multiple E-glass fibre bundles. Two sets of filament wound composite tubes were manufactured. One set was wound using a conventional resin bath system. The second set incorporated an optimised spreading station prior to the resin bath. The results of the analysis of physical properties suggest that fibre volume fraction is slightly lower in tubes wound using a spreading station and these tubes also have a higher void content. The average density values are relatively similar although the tubes wound with the spreading station have less variance in the individual values. Further analysis is needed to determine the effect of spreading during manufacture on the mechanical properties of filament wound composite tubes.
