The Handbook of Pultrusion Technology provides the latest information on the pultrusion process, including materials, processing, and equipment. With detailed coverage of industry practices and troubleshooting techniques, this book is an essential resource for anyone involved in the pultrusion industry.

What is Pultrusion?

Pultrusion is a continuous manufacturing process in which a fiber-reinforced polymer (FRP) composite is produced by pulling a continuous strand of fibers through a resin bath and then through a heated die. The die forms the final shape of the composite, and the heat cures the resin.

Applications of Pultrusion

Pultruded FRP composites are used in a wide variety of applications, including:

Structural components in the construction industry
Electrical insulation in the electrical industry
Reinforcements in the automotive industry
Medical devices in the healthcare industry

Benefits of Pultrusion

Pultruded FRP composites offer a number of advantages over other materials, including:

High strength and stiffness
Lightweight
Corrosion resistance
Electrical insulation
Design flexibility

The Pultrusion Process

The pultrusion process consists of the following steps:

A continuous strand of fibers is pulled through a resin bath.
The resin-impregnated fibers are then pulled through a heated die.
The die forms the final shape of the composite, and the heat cures the resin.
The cured composite is then cut to the desired length.

Materials Used in Pultrusion

The following materials are commonly used in pultrusion:

Fibers: Glass, carbon, and aramid fibers are the most commonly used fibers in pultrusion.
Resins: Polyester, epoxy, and vinyl ester resins are the most commonly used resins in pultrusion.
Additives: A variety of additives can be used to modify the properties of pultruded composites, including fillers, pigments, and flame retardants.

Processing of Pultruded Composites

The pultrusion process can be divided into the following stages:

Preparation: The fibers are cleaned and sized, and the resin is prepared.
Pultrusion: The fibers are pulled through the resin bath and the die.
Curing: The composite is cured in an oven or by other means.
Post-processing: The composite is cut to the desired length and finished.

Equipment Used in Pultrusion

The following equipment is used in pultrusion:

Pultrusion machine: The pultrusion machine pulls the fibers through the resin bath and the die.
Resin bath: The resin bath contains the resin that is used to impregnate the fibers.
Die: The die forms the final shape of the composite.
Oven: The oven is used to cure the composite.

Troubleshooting Pultrusion Problems

The following are some common problems that can occur during pultrusion:

Fiber breakage: Fiber breakage can be caused by a number of factors, including excessive tension on the fibers, improper sizing of the fibers, or contamination of the resin.
Resin voids: Resin voids can be caused by a number of factors, including inadequate impregnation of the fibers, improper curing of the resin, or contamination of the resin.
Delamination: Delamination can be caused by a number of factors, including poor bonding between the fibers and the resin, improper curing of the resin, or excessive tension on the composite.
