Glass fabric 80 g/m² (Finish FK 144, aero, plain weave), width 103 cm

International Style 1610 (formerly Interglas 90070) with FK 144 finish is a lightweight E-glass fabric in plain weave. With an areal weight of 80 g/m², it is suitable for thin glass-fibre laminates, surface reinforcement and facing plies where low laminate build-up is to be combined with good handling stability of the dry fabric.

Benefits of the Fabric

With an areal weight of 80 g/m², International Style 1610 enables lightweight and thin glass-fibre laminates. Identical EC 9-34 yarn in the warp and weft directions, combined with the similar thread counts of 12.0 ends/cm and 11.5 picks/cm, provides a largely uniform fibre distribution in both principal directions.

The high number of yarn interlacings in the plain weave provides good resistance to yarn displacement. The fabric therefore remains comparatively stable during cutting, handling and positioning and is particularly suitable for controlled lay-up on flat and gently curved components.

The FK 144 finish and classification as a material according to aviation standard make this fabric particularly relevant for applications where a correspondingly specified glass fabric is required.

Applications

The 80 g/m² glass fabric is suitable for lightweight sandwich components, surface reinforcement and smaller GFRP components and panels. Its low areal weight allows thin facing and reinforcement plies to be produced.

Typical applications:

• Sandwich components and lightweight facing plies
• Surface reinforcement and coverings
• Small GFRP components
• Thin GFRP panels
• Lightweight and model-making applications
• Applications requiring a material according to aviation standard

Suitable Resin Systems

The glass fabric can be processed with suitable epoxy, polyester and vinyl ester resin systems. Low-viscosity laminating resins are advantageous for thin laminates because they facilitate uniform wet-out of the fabric.

For aviation applications, the fabric must be used with the resin system specified or approved for the particular application and in accordance with the applicable processing requirements.

Benefits of the 103 cm Width

The 103 cm working width is particularly suitable for small to medium-sized components, panels and sandwich components. Parts within the available fabric width can be covered without an additional longitudinal joint.

For narrower components, the width also allows efficient nesting of cut pieces and good material utilisation.

Technical Notes

Plain Weave
The high number of yarn interlacings gives the plain weave good resistance to yarn displacement. This facilitates cutting and positioning with minimal fabric distortion.

Component Geometry
The dimensionally stable plain-weave construction is particularly suitable for flat and gently curved geometries. For more strongly three-dimensional components, a comparable twill-weave fabric generally provides better drapability.

Resin Application
Apply the resin uniformly and in an amount appropriate for the fabric. Excess resin increases laminate weight and thickness without increasing the fibre content or the fibre-related reinforcing contribution.

Sandwich Structures
The fabric can be used for lightweight facing plies in sandwich structures. The required facing lay-up depends on the core material, component geometry and mechanical loading.

Aviation Applications
For aviation applications, the applicable material, processing and approval requirements for the specific component construction must be observed.
