KEVLAR® 4HS Weave Fabric

KEVLAR® 4HS Weave Fabric
5 oz/sq yd, 50" Wide, 0.012" Thick, 17 x 17 4HS Weave


KEVLAR® in 4HS is often preferred for maximum conformability. 4HS construction means that one filling thread (width) floats over 3 warp (length) threads resulting in a fabric that looks different on each side and features conisiderable conformability and drape. Along with being highly impact resistant, this satin weave is most often selected for aerospace and structural designs. Generally, KEVLAR® is not suited for applications that call for compressive strength. It is meant to be used with a resin, like our System #2000 epoxy.

Before starting your project with KEVLAR®, consider:
  • To produce a symmetrical laminate with a satin weave, you must invert alternating plies.
  • KEVLAR® is difficult to cut, sand, and machine. Consider a dedicated pair of serrated scissors, like our #1731-A.
  • Our KEVLAR® is not meant to be sewn.
  • Unused KEVLAR® should be stored away from UV light.

GINGHER® Serrated Scissor
Designed to cut KEVLAR®

Our GINGHER® Serrated Scissors feature a serrated edge which allows you to cut KEVLAR® without pulling fibers along with the scissor. The serrated blade holds the fabric in place while the smooth blade cuts. These scissors can be used with prepreg fabrics, dry fabrics, or even during a wet layup. They are compatible with fiberglass, carbon fiber and KEVLAR®, however, the same pair should not be used for KEVLAR® and any other fabric. If used during a wet layup, we recommend soaking the blades in acetone after use and wiping clean prior to storage.

The Perfect Line Tape
Make clean, straight cuts and prevent fraying

Our #1735 Perfect Line Tape is such a reliable way to ensure straight cuts and clean fabric edges, we use it ourselves! Every roll of fabric that leaves our shop was cut with Perfect Line Tape.

To use, apply the tape onto your reinforcement and cut along the dashed line printed between the two text lines. You get an even cut and prevent fraying on both edges. This low cost item is an effective solution to the fraying associated with cutting expensive fabrics features a medium-tack adhesive that removes and leaves a negligible residue, allowing the fabric to be laminated all the way to the edge.

Can be applied directly to Carbon Fiber and Fiberglass fabrics. We recommend first applying a layer of standard blue painter's tape below Perfect Line tape when cutting Kevlar fabrics.

Perfect Line tape is best used to make straight cuts, but can be sectioned for use on gradual, simple curves. 55 yards per roll.
