Glass fabric 124 g/m² (plain weave) 68.6 cm

USA: width 27", weight 3.66 oz/yd²

Lightweight 124 g/m² plain weave glass fibre fabric for surfboard construction and thin-walled GFRP laminates.

The glass fibre fabric with A905 finish is suitable for use with epoxy, polyester and vinyl ester resins. Its width of 68.6 cm (27 inches) corresponds to an internationally established standard size for glass fibre fabrics used in surfboard construction.

Product properties

Plain weave: Uniform, dimensionally stable fabric structure.
Universal resin compatibility: Suitable for UP, VE and EP resin systems.
Standard surfboard width: 68.6 cm (27 inches) for surfboard construction.

Technical data

Manufacturer's grade	01522
Areal weight	124 g/m² (± 5%)
Weave	Plain weave
Width	68.6 cm (27 inches)
Sizing / finish	A905
Warp / weft yarn	EC9-34 × 2 / EC9-34 × 2
Warp / weft thread count	9.3 / 8.7 threads/cm (± 5%)
Dry fabric thickness	0.14 mm (± 5%)
Breaking strength, warp / weft	> 53 / > 35 N/cm

Fabric advantages

The thread count of 9.3 threads/cm in the warp direction and 8.7 threads/cm in the weft direction produces a nearly balanced fabric structure. Identical yarns in both directions support uniform reinforcement.

Applications and processing

Applications

Surfboard construction and repairs
Lightweight, thin-walled GFRP components
Model making and mould making
Reinforcement of shell components

Processing information

The fabric can be processed with suitable epoxy, polyester and vinyl ester resins. For surfboards with EPS foam cores, suitable epoxy resins must be used, as styrene-containing polyester and vinyl ester resins can attack the foam.

When planning cutting layouts, allow sufficient overlap to wrap the fabric around the surfboard edges (rails).

Calculated laminate values

Indicative values for hand lay-up laminates with a glass fibre volume fraction of 35%:

Resin consumption	Approx. 98 g/m²
Laminate thickness	Approx. 0.136 mm
Laminate weight	Approx. 222 g/m²

Calculated using a glass fibre density of 2.55 g/cm³ and a resin density of 1.10 g/cm³. Actual values depend on the resin system and processing method.

Technical information

Plain weave

In a plain weave, warp and weft yarns alternate over and under each other, creating a dimensionally stable fabric structure. Compared with twill fabrics, its ability to conform to strongly curved contours is more limited.

Fabric width

The width of 68.6 cm corresponds to 27 inches and is an internationally established size for surfboard glass fibre fabrics. When planning cutting layouts, the board geometry and the overlap required to wrap the fabric around the rails must be considered.

Manufacturer's data

The breaking strength specified in the manufacturer's data sheet is greater than 53 N/cm in the warp direction and greater than 35 N/cm in the weft direction. These values refer to the dry fabric, not the finished laminate.
