Pultrusion Process

The Pultrusion Process is used to create composite materials consisting of a reinforcing material encased in a synthetic resin. Pultruded sections are being used to replace metals in many applications because composites are light, strong, non-corroding and need little maintenance.

The pultrusion process involves pulling fibre or mat reinforcing material through:

  • a resin tank the impregnates the fibres with resin
  • then through preforming guides that give the composite its initial shape
  • then through heated dies that shape and cure the resin / reinforcement mixture 
  • the fully cured composite is cooled and pulled to a circular saw or bandsaw where it is cut into designated lengths.
  

Applications

Fibre reinforced plastic (FRP) composites are being used to replace metals in many applications including:

  • rods and poles
    • gardening tool handles
    • broom handles
    • plant supporting poles
    • fence poles and posts
    • flag poles
    • lamp posts
    • tent poles
    • poles for sports
  • electric conduit and sheathing
  • rails and fences
  • construction industry applications, e.g. bridges, walkways, tanks and decks and many others where a structural section is required

Learn about Plastics

We use animations and supporting technology notes to describe plastics and plastics processes.

Animations illustrate plastics processes in probably the most clear way possible, making plastics processes easy to understand, easy to learn and easy to remember.

Our plastics technology notes and animations describe all the major processes including:

Plastics Module

Our new Plastics Module developed from the work in the KS3 and KS4 D&T packages. It is a complete package that includes:

  • plastics technology notes
  • animations of plastics processes
  • a range of exercises that include design and make assignments (DMAs), focused practical tasks (FPTs) and technology questions.

To make teaching easier, the technology theory notes and exercises are in digital format, making them suitable for computers and whiteboards; and in PDF format, which makes it simple to print and duplicate A4 theory notes and worksheets.
