300 g/m² Plain Weave Fiberglass Fabric

300 g/m² Plain Weave Fiberglass Fabric

300 g/m² Plain Weave Fiberglass Fabric is a woven glass fiber reinforcement material used in composite laminate manufacturing. Featuring a nominal areal weight of 300 g/m² and a plain weave construction, the fabric consists of interlaced glass fiber yarns arranged in the warp and weft directions.

The fabric is used as a reinforcing layer in resin-based composite laminates. Its woven structure positions glass fibers along two principal directions, providing bidirectional reinforcement for composite components. The nominal areal weight of 300 g/m² represents the dry mass of the fabric per unit area.

Plain Weave (1/1) Construction

Plain weave is a fundamental textile construction in which each warp yarn passes alternately over and under successive weft yarns. This 1/1 interlacing pattern mechanically connects the yarns and helps maintain the structural integrity of the fabric.

The regular woven construction helps reduce yarn displacement during cutting, handling, and positioning of the dry fabric. Plain weave fiberglass fabrics can be used for laminating flat surfaces and components with relatively simple geometries.

Technical Specifications

Fabric Characteristics

• Bidirectional reinforcement: Glass fiber yarns arranged in the warp and weft directions provide reinforcement along two principal laminate axes.
• Regular weave construction: The 1/1 interlacing pattern helps maintain the woven structure of the fabric.
• Weave stability: Mechanical interlacing helps limit yarn displacement during dry fabric cutting and handling.
• Composite lamination: When impregnated with a suitable resin system, the fabric forms a fiber reinforcement layer within composite laminates.

Applications

• Composite panel and sheet manufacturing
• Fiberglass-reinforced composite component production
• Composite mould manufacturing
• Resin-based composite laminate production
• Hand lay-up composite manufacturing

Application Information

The fiberglass fabric can be impregnated with a suitable resin system and used as a reinforcing layer in composite laminates. In hand lay-up processing, the fabric is positioned on the prepared mould surface and impregnated with the selected resin system.

The number of fabric layers, fiber orientation, and laminate configuration should be determined according to the geometry and design requirements of the finished component. Resin compatibility and processing conditions should be evaluated according to the relevant material technical data sheets.
