More Technology Information

What is epoxy?

Epoxies are thermosetting polymer resins where the resin molecule contains one or more epoxide

groups. The chemistry can be adjusted to perfect the molecular weight or viscosity as required by 

the end use. Their are two primary types of epoxies, glycidyl epoxy and non-glycidyl. Glycidyl epoxy 

resins can be further defined as either glycidyl-amine, glycidyl-ester, or glycidyl ether. 

Non-gylcidyl epoxy resins are either aliphatic or cyloaliphatic resins.

What is epoxy resins commonly used for?

In the realm of fiber reinforced polymers (plastics), epoxy is used as the resin matrix to efficiently

 hold the fiber is place. It is compatible with all common reinforcing fibers including fiberglass, 

carbon fiber, aramid, and basalt.

Common products and manufacturing methods for fiber reinforced epoxy include:

Ø Pressure vessels

Ø Pipes

Ø Rocket housings

Ø Recreational equipment

Ø Insulator rods

Ø Arrow shafts

Ø Compression Molding

Ø Aircraft parts

Ø Skis and snowboards

Ø Skateboards

Ø Circuit boards

Ø Prepreg and autoclave

Ø Aerospace components

Ø Bicycle frames

Ø Hockey sticks

Ø Vacuum Infusion

Ø Boats

Ø Wind turbine blades

Advantages of Epoxy

When compared to other traditional thermoset or thermoplastic resins, epoxy resins 

have distinct advantages, including:

Ø Low shrink during cure

Ø Excellent moisture resistance

Ø Excellent chemical resistance

Ø Good electrical properties

Ø Increased mechanical and fatigue strength

Ø Impact resistant

Ø No VOCs

Ø Long shelf life

What is Pultrusion?

Pultrusion is a method of manufacturing continuous fiber reinforced composites profiles. 

The manufacturing process is that where molten plastic or metal is pushed through a die. 

However, with pultrusion, the material is "pulled" through a die.

The Pultrusion Process

Raw fiber (glass, carbon, aramid, etc) is pulled off of doffs or rolls from a creel racking system.

The fiber is pulled through a bath of thermosetting resin. Most often the resin is polyester resin, 

but also vinyl ester, epoxy, and more recently, urethane.

a. Using guiding systems, the impregnated fiber is led through a heated die. The entrance of 

the die is often cooled to avoid curing the resin while excess resin is squeezed off.

b. As the fiber and resin is pulled through the heated die, the resin cures and exits as a fully 

formed composite. The shape of the pultruded composite part will match the shape of the die.

c. All of this is accomplished by a set of "pullers" or "grippers" which are pulling this material at 

a consistent rate.

d. At the end of the composite machine is a cut-off saw, which cuts the pultrued profiles at a

desired leng

What is Fiberglass?

Fiberglass reinforced plastics (FRP), are a composite material consisting of fiberglass

reinforcements in a plastic (polymer) matrix. The variations of both reinforcements and polymers

allow an incredible range of physical and mechanical properties which can be developed specifically 

for the performance required.

Advantages of Fiberglass Reinforced Plastics (FRP)

Fiberglass reinforced plastic composites are strong, lightweight, corrosion resistant, thermally and 

electrically nonconductive, RF transparent, and virtually maintenance free. There are unique

properties of FRP, that make them suitable and desirable for a wide range of product applications.

FRP Advantages include:

a. Strength & Durability

b. Versatility and Freedom Of Design

c. Affordability and Cost Effectiveness

d. Unique Physical Properties

Fiberglass is an attractive, lightweight, and durable material with one of the highest strength 

to weight ratios available for component fabrication. It is also highly resistant to environmental 

extremes. Fiberglass reinforced plastics (FRP) do not rust, are highly resistant to corrosives, 

and are able to withstand temperature extremes as low as -80° F or as high as 200°F.

What is composite?

"composite" is when two or more different materials are combined together to create a 

superior and unique material. 

This is an extremely broad definition that holds true for all composites, however, more recently

 the term "composite"

describes reinforced plastics.

Background on Composites

Since the days of adobe, the use of composites has evolved to commonly incorporate a structural 

fiber and a plastic, this is known as Fiber Reinforced Plastics, or FRP for short. Like straw, 

the fiber provides the structure and strength to the composite, while a plastic polymer 

holds the fiber together. Common types of fibers used in FRP composites include:

Fiberglass;Carbon Fiber;Aramid Fiber; Boron Fiber;Basalt Fiber;Natural Fiber (Wood, Flax, Hemp, etc.)

What is the composite commonly used for?

Aircraft;Boats and marine;Sporting equipment;Automotive components;Wind turbine blades
