What we stock for this work

Multi stage rocket climbing through the upper atmosphere on launch.

From airframes and fin cans to nose cones, the same fiberglass, carbon, and epoxy systems build parts that fly.

Common applications

The jobs this catalog gets built for, and the materials each one calls for.

01
Filament-wound and hand-laid airframe tubes
biaxial and woven fiberglass over a mandrel with epoxy for a stiff, straight body tube that holds its shape under thrust.
02
Fin cans and fin reinforcement
carbon fiber or fiberglass tip-to-tip layup that ties the fins into the body tube so they survive max-Q and recovery loads.
03
Nose cones and transitions
layup over a plug or pulled from a mold, faired with microballoon filler for a clean ogive.
04
Coupler and bulkhead bonding
epoxy thickened with fumed silica for structural fillets that take the shock-cord and motor-retention loads.
05
Molds and tooling
release agents and surfacing materials for builders pulling repeat parts off a master plug.
06
Surface fairing and finish
microballoon fairing compound sanded to a clean aerodynamic skin on airframes and nose cones before paint.

Frequently asked questions

What fiberglass do high power rocketry builders use for airframes?

Most builders reach for woven fiberglass and 1708 biaxial set in epoxy. The 1708 lays in a 0/90 or 45/45 bias plus a chopped strand backer, so a single ply builds a stiff, straight wall fast. Lighter woven cloth (around 6 to 10 oz) goes on for skins and tip-to-tip work where weight matters.

Should I use epoxy or polyester resin for a rocket airframe?

Epoxy. It bonds to almost anything, has higher strength and better fatigue resistance than polyester, and holds up to the heat and shock a high power flight puts on the airframe. Match the hardener to your working time and the cure temperature you can hold.

Do you stock carbon fiber for fin reinforcement?

Yes. The carbon fiber line carries plain weave and twill cloth that builders use for tip-to-tip fin layups and fin-can reinforcement where stiffness per gram matters. Carbon and fiberglass both bond cleanly into an epoxy laminate, so many builders run a hybrid.

What release agent do I need to pull a part off a mold?

For a nose cone or airframe pulled from a mold or plug, use a film-forming release such as PVA over a mold wax, or a dedicated release agent on a sealed mold. The release agents in the catalog let you pull repeat parts off a master plug without bonding to it.

Can a rocketry club or team get bulk pricing?

Yes. Teams, clubs, and shops building airframes for repeat launches can apply for a Wholesale Pro account for catalog pricing on bulk fiberglass, epoxy, and release agents. Apply through the request a bulk quote link on this page.
