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^® 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).
