Pultrusion

The first commercial pultrusions were provided by Glastic Company of Cleveland, Ohio under the patent filed in 1952 by Rodger B.

The patent issued to W. B. Goldsworthy in 1959 helped initiate the promotion and knowledge spread within the industry.

Engineered Composites Ltd in the UK has led the improvements in the process over the last 38 years working with major production houses and universities.

Ecological cleanness of manufactured products, in contrast to composites on thermosetting resins base, as well as practically unlimited possibilities of recycling (processing) after the resource depletion appear to be forcible arguments in favor of reinforced thermoplastics.

New developments (see process modifications) which enable the manufacturing not only of straight but also curved profiles are actually pushing the demand for this technology, especially in the automotive sector.

Pultrusion technology of manufacturing of fiber composites with polymer matrix appears to be energy-efficient and resource-saving.

It also is beneficiary for a number of tasks in the linear process especially if quite complex textile reinforcements with a low rate of distortion are needed.
