Which materials make the strongest composites? Woven or knit or crochet? Which stitch, hook size, and fiber geometry creates the most structurally sound and lightweight material? Check out our material studies to see what we learned.
Hand crocheted (single crochet, size 4 hook)
Composite materials are traditionally used as built up layers of perpendicular woven fiberglass to provide fiber strength in all directions. We hypothesized that a crochet or knit material, whose interlocking loops and omni-directional fibers traditionally create stretch, might provide more strength and stability when paired with resin.
Hand crocheted, lace crochet stitch
Because cotton has long staple fibers and is so absorbent, it created a promising composite.

single crochet. size 10 hook
This particular Kevlar was not absorbent at all and thus was one of our weakest samples.
