Fiberglass & Carbon

Every reinforcement we cut, in one place

Glass, carbon and aramid, from 0.75 oz mat through 24 oz roving and 19.7 oz 12K carbon. Cut to the yard from full rolls, or bought as a full roll. This is the parent page. The child collections below are where the detail lives.

Start with what the job needs

Woven cloth is the general answer: strength with a clean surface that finishes well, 3 oz to 40 oz, in plain, twill and satin weave. Chopped strand mat builds thickness fast and conforms to shape, and it only works with polyester or vinyl ester resin. Stitched biaxial such as 1708 puts the fibres on the 45s where a transom or stringer actually needs them. Woven roving at 18 and 24 oz is the cheapest way to add bulk in a hull laminate.

When to spend on carbon or aramid

Carbon fiber is for stiffness per unit weight, not for toughness, and it is worth the money on spars, foils, panels and anywhere flex is the enemy. Kevlar aramid is the opposite trade: it is what you want where something is going to get hit, like a skid plate or a hull bottom, because it absorbs impact instead of shattering. Neither is a general upgrade over glass, and both cost considerably more.

Tape instead of cutting strips

Glass tape and carbon tape come in 1 in to 12 in widths with finished edges. For seams, chines, stringers and joints they are faster and cleaner than slitting a wide roll, and you are not paying for the yardage you throw away.

How much you need

The layup calculator takes a full ply schedule, peel ply and all, and returns fabric yardage plus the resin to wet it out.
