FAQ: What Resin Is Used For Kevlar Canoe Construction?

What kind of epoxy do you use for a canoe?

Epoxy resin works best in a warm envionment, about 24 degrees Celcius (75 degrees Fahrenheit). We recommend West System 105 resin, with 207 hardener.

What resin is used with Kevlar?

Kevlar® should be used with an epoxy or vinyl ester resin.

How are Kevlar canoes made?

The canoes are made by gluing several layers of Kevlar fabric together to create a solid laminate material. But of course there are many more steps to the process than that, and much more skilled workmanship involved.

What composite material is used for the manufacture of canoes?

Fiber reinforced composites Fiberglass is the most common material used in manufacturing canoes. Fiberglass is not expensive, can be molded to any shape, and is easy to repair. Kevlar is popular with paddlers looking for a light, durable boat that will not be taken in whitewater.

Which canoe material is best?

Royalex. For years Royalex has been the go-to material for most casual canoe buyers. Lighter than polyethylene and with more variety of design than aluminum, Royalex is essentially a plastic sandwich made of layers of vinyl, plastic and rigid foam.

Is Kevlar expensive?

Kevlar production is expensive because of the difficulties arising from using concentrated sulfuric acid, needed to keep the water-insoluble polymer in solution during its synthesis and spinning.

Is Kevlar better than steel?

Kevlar is five times stronger than steel on an equal weight basis and provides reliable performance and solid strength. To achieve both the strength and stiffness of Kevlar, the molecular chains within the organic fiber needed to be fully extended and perfectly aligned to make them strong, stiff and tough.

Is Kevlar stronger than fiberglass?

Because Kevlar® is much higher in stiffness and tensile strength than fiberglass, the builder can use fewer layers of cloth and in turn use much less resin reducing weight by approximately 15-20%. Kevlar® is much more expensive than fiberglass and much more difficult to repair.

How much does it cost to build a Kevlar canoe?

The canoe weighs 60 pounds, cost $1,000 and took about four months to build.

Why did they stop making Royalex canoes?

Royalex was developed by Uniroyal in the 1970s. In 2013, plastics company PolyOne, of Avon Lake, Ohio purchased Spartech, and decided to shut down Royalex production due to its low volume. The last sheets of Royalex were shipped from the factory in December, 2013. Production will be shut down in April 2014.

Is Kevlar fragile?

Standard Kevlar Canoes are hand-laid in a similar fashion to ‘Standard’ fiberglass canoes, except a stronger, more expensive Vinylester resin is used in the production process. Note: Standard Kevlar canoes are the least expensive but weigh more and are the most fragile of the composite Kevlar choices.

What is the most durable canoe?

Roto-Molded/Polyethylene Canoes These are the most common type of canoes on the market today. They are great for general recreational because they are the most affordable and are extremely durable. Many outfitters and rental facilities use these due their high-level of abuse tolerance.

What are canoes normally made of?

Canoes are made of wood, canvas over wood frames, aluminum, molded plastic, fibreglass, or synthetic fibre composites. The optimum material for canoe construction varies by the intended usage of the craft.
