C-Flex
C-Flex is a unidirectional fiberglass building material originally developed for the manufacturing of custom boats. Since its invention, countless structures, marine and otherwise, of all shapes, sizes and complexity have been affordably built using this simple construction method. The design of C-Flex allows any form to be built using simple and inexpensive framing procedures instead of costly molding methods.
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.
The C-Flex material system and related application technique can accommodate a wide range of boat building needs, from recreational yachts to commercial fishing boats. In a boat building application it can be used with a temporary framework, a traditional wooden framework, or a permanent and temporary framework combination. The C-flex, a dry fiberglass fabric with longitudinal rods, is typically attached to the framing and then saturated with a slow curing resin. After the resin cures, additional layers of reinforcement are added to develop the full hull thickness.

C-flex is an excellent solution for preserving the life and character of vintage wooden boats, because it can be attached on a wooden hull to create a stronger and more durable hull structure. The C-Flex is applied to the prepared hull with an Elastomeric Adhesive, which creates a strong but flexible interface between the wood and the exterior fiberglass. The hull is then laminated with additional layers of reinforcements to the desired strength level.
C-Flex is manufactured exclusively by Seemann Composites LLC. 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'.
CF-65 is the heavier grade and should be considered for use in most
industrial or commercial applications and boat building where weight
is not a crucial factor.
CF-39 is lighter and should be considered for lightweight boats
(canoes, racing boats, etc.) and any other weight critical application.
C-Flex is sold through our exclusive distributor Sea Chest Marine. http://www.seachestdistributors.com
