Chopped strand mat 225 g/m², width 127 cm
USA: width 49.21", weight 6.6 oz/yd²
Fine glass fibre mat for thinner laminates and controlled layer build-up.
With a calculated laminate thickness of approx. 0.58 mm per layer, it is ideal for thin-walled GRP components, repairs and applications where the required laminate thickness needs to be built up in smaller increments. The fine 15 tex split strand structure promotes a uniform surface.
Glass fibre mat 225 g/m²
Powder-bound glass fibre mat made from chopped, randomly oriented glass fibres. The fibre arrangement provides largely direction-independent reinforcement across the surface. The mat wets out easily and is particularly suitable for conventional hand lay-up processing.
At 225 g/m², this is the lightest grade in the product range. It is recommended for thinner laminates or where laminate thickness needs to be built up in smaller, controlled increments. Typical applications include smaller GRP components, moulds, panels, repairs, boatbuilding and automotive parts.
When is 225 g/m² the right choice?
- for thinner and lighter GRP laminates
- for finely controlled build-up of component thickness
- for smaller components and repair areas
- for contours where a lighter mat is easier to conform
- when a lower thickness build-up per layer is required
Which glass fibre mat should I choose?
| Area weight | Laminate thickness per layer* | Recommendation |
| 225 g/m² | approx. 0.58 mm | Thinner laminates, finely controlled layer build-up, smaller components and repairs |
| View glass fibre mat 300 g/m² → | approx. 0.77 mm | Universal standard grade for general laminating work |
| View glass fibre mat 450 g/m² → | approx. 1.15 mm | Greater laminate thicknesses and faster material build-up with fewer layers |
* Calculated value at 15 vol.% fibre content. The actual laminate thickness may vary depending on resin quantity, processing and compaction.
Processing tips
First apply the resin evenly to the substrate, position the pre-cut mat and then wet it out completely with resin. As the mat becomes saturated, it softens and conforms well to the component contour.
Carefully remove trapped air using a brush or laminating roller. Several layers can be applied wet-on-wet. Ensure complete wet-out of all layers and avoid unnecessary excess resin.
Tip: Glass fibre mats absorb considerably more resin than glass fabrics. Calculate the resin requirement before starting and only mix quantities of resin and hardener that can safely be processed within the working time.
Suitable resin systems
Suitable for polyester and vinyl ester resins as well as suitable epoxy resin systems. With epoxy resins, the mat binder may behave differently than with polyester resins, which can reduce drapability.
Artistic applications
Glass fibre mats are also very suitable for artistic and decorative projects, for example when the characteristic fibre structure is intended to remain visible. For such applications, we recommend the highly transparent Epoxy Resin HT 2 + Hardener HT 2 (Item No. 105100). It is particularly suitable for applications where a clear and highly transparent resin matrix is required. n/
