What is C flex fiberglass?

What is C flex fiberglass?

C-Flex is a unidirectional fiberglass building material originally developed for the manufacturing of custom boats. The C-flex, a dry fiberglass fabric with longitudinal rods, is typically attached to the framing and then saturated with a slow curing resin.

Do fiberglass boats Flex?

The softening of the polyester/fiberglass matrix is ongoing and inevitable with flexing. The boat hull is more than a quarter of an inch thick which would have been pretty stiff when new. Each time the panel flexes there is micro fracturing, the more deviation that the panel experiences the larger the fracturing.

What is the best boat building material?

Steel is one of the most popular materials used for boats and has consistently been the material of choice for the past century. Its high strength, durability, resistance to abrasion, and relatively low cost are some of the main reasons why steel is widely used in the industry.

What is FRP in boat building?

The term FRP is generally accepted to mean fibre reinforced plastic. The names fibreglass reinforced polyester, resinglass, and glass reinforced plastic (GRP) are also used. This material is a plastic and is unique in that it is made by the user in situ.

Who makes C Flex?

Saint-Gobain North America
C-Flex® | Saint-Gobain North America.

What is C Flex material?

C-Flex® is the original patented thermoplastic elastomer tubing specifically designed to meet the critical demands of pharmaceutical and biopharmaceutical applications for fluid processing. C-Flex tubing for Biopharma Manufacturing is specifically designed for aseptic welding connections and sealing disconnection.

How do you flex fiberglass?

Apply heat to the surface of the fiberglass for about 30 seconds. Hold the heat gun about 3 inches from the fiberglass. Move the heat gun slowly up and down the area you want to bend. Apply more heat or less heat by moving the heat gun closer to, or farther away from, the fiberglass.

What is the best hull material for salt water?

A relatively expensive metal used only very occasionally in boatbuilding is cupronickel. Arguably the ideal metal for boat hulls, cupronickel is reasonably tough, highly resistant to corrosion in seawater, and is (because of its copper content) a very effective antifouling metal.

Why is glass reinforced plastic is used for building boats?

It is a popular alternative over metal, wood, or plastic. Where exposure to harsh environments is a concern, GRP can aid resistance to UV light, extreme temperatures, salt air, and a variety of chemicals. As GRP is chemically inert and corrosion-resistant it is often a cheaper alternative to stainless steel.

How FRP boats are made?

Most fiberglass boats are built from a female mold that accepts multiple layers of fiberglass cloth or matt and resin that eventually cure together to form a hull shape. Next, a thick layer of high-quality resin called gelcoat is sprayed into the mold.

What is C-Flex made of?

C-Flex tubing is manufactured from pharmaceutical-grade thermoplastic elastomer, is fully characterized, validated and tested to a variety of specifications. Extensive biological, chemical, physical properties and extractable testing is available to assist in the validation of C-Flex application.

How is C Flex used in boat construction?

Creates a boat with high longitudinal strength, as the fibreglass ‘rods’ in C‑flex are not only relatively large and solid compared to all other glass fibres but they are also laid in as one piece from bow to stern. C‑flex lays on as multiple lengthwise battens and therefore provides basically fair lines over the construction form.

How does C Flex fiberglass hold its shape?

Each “plank” of C-Flex contains small semi-rigid rods in the longitudinal direction. These rods allow the fiberglass to hold its form while resin is applied to the cloth. This eliminates the need for a full mold as is used in traditional fiberglass construction.

Can a C Flex boat be built without a mold?

Aside from the obvious advantage of being able to build an all fibreglass boat without a mold, C-Flex also affords the designer and builder the opportunity to save weight over a conventional fibreglass laminate without sacrificing strength.

How big is a C Flex steel hull?

The hull is then laminated with additional layers of reinforcements to the desired strength level. C-Flex is manufactured exclusively by Seemann Composites Inc. in two “grades” or weights, CF-65 and CF-39. All planks are 12″ wide and are made in continuous lengths of up to 250′.
