Definition
Referring to a manufacturing process where raw composite materials are pulled through a heated die to form continuous, reinforced structural shapes.
Etymology
The word is a portmanteau of the words 'pull' and 'extrude'. It was coined in the mid-20th century to describe this distinct fabrication process for reinforced plastics.
In the news
The article discusses the properties of glass fiber composites that were created using this specific manufacturing method. It is central to understanding how the materials were formed before being tested for heat resistance.
