Dual-axis method and machine for producing pre-preg |
| abstract |
An improved method for the manufacturing of wavy pre-preg material that moves a first group of rollers in a transverse and a longitudinal direction with respect to a second group of rollers, to place a sinuous waveform in a fiber reinforced matrix for the manufacture of a wavy pre-preg material. The fabrication of wavy fiber pre-preg (fibers pre-impregnated with epoxy resin as an example) can be accomplished with an automated control system that permits the creation of non-periodic or mixed waveforms. The improved apparatus for this process allows for a more accurate placement of fibers, production of a wider variety of usable waveforms, and increased quality of pre-preg produced. |
