Compoflex®

Fibertex Compoflex® products are breathable micro-porous peeling materials, designed to replace up to three consumables – peel ply, release film and breather – with a single layer in composite manufacturing.

Compoflex

Compoflex® for infusion
In the resin infusion process, dry fibre material is placed directly in the mould. A distribution fabric or grid is installed to ensure correct resin flow and optimal vacuum distribution. A peel-ply is installed as a separator between the dry fibre material and the distribution fabric. Compoflex® 150 replaces the peel-ply and ensures easy peeling, leaving a clean surface.

Compoflex® for vacuum moulding
In the vacuum bagging process, the lay-up consists of a laminate, peel-ply, release film and a breather/bleeder fabric. Compoflex® can replace all of these products, simplifying the process.

Maximum use temperature
The melting point for polypropylene is 165°C (329°F) and our recommended working temperature is approx. 145°C (293°F). However, we do have customers using Compoflex at 200°C (392°F). This is because Compoflex performs before the temperature exceeds the melting point. Peeling is just as easy and the material becomes stable again. We recommend conducting a test on a small part first.

Features and installation of Compoflex®

  • Easy lay-up with only one product .
  • Always place the smooth side against the laminate.
  • Always place the fluffy side against the vacuum bag.
  • We recommend testing on a small part, prior to full scale installation.
  • This material can be pre-cut with a CNC or hand cut with scissors.
  • Overlap is possible.
  • This material works well with polyester, vinylester, epoxy, phenolic and other types of resin.
  • The melting point for polypropylene is 165°C (329°F) Recommended working temperature is approx. 145°C (293°F). Maximum temperature, depending on process, is 200°C (392°F).
