  • Open-work knitted textile resin infusion medium and reinforcing composite lamina
    Patent number: 7579292
    Abstract: Resin infusion medium and reinforcing composite lamina textile constituted by a warp knit open work structure produced in the form of polygons of which at least some of the edges are defined by knops such as to give prominence to the design to provide for fluidic channels, the knops being knitted to be sufficiently non-compressible in order to resist collapse of the fluid channels during compression of the composite preform under vacuum induced process pressure.

  • Three-dimensional spacer fabric resin interlaminar infusion media process and vacuum-induced reinforcing composite laminate structures
    Patent number: 7060156
    Abstract: A three-dimensional spacer fabric resin interlaminar infusion medium and reinforcing composite lamina for use in the vacuum-induced manufacture of fiber reinforced polymer composites is described. This use of the three-dimensional spacer fabric as a composite interlaminar component improves both the vacuum-induced resin infusion flow rate and laminate quality control and aids in the achievement of enhanced resin uniformity distribution throughout the laminate.
