Key Advantages of Glass Fiber Stitched Mat

1. Binder-Free Mechanical Structure

Unlike conventional chopped strand mat that relies on powder or emulsion binders,the chopped E-glass strands in this stitched mat are mechanically held together with polyester stitching yarn.

The binder-free construction reduces dependence on chemical bonding agents and provides a stable reinforcement structure for composite processing.

This structure is particularly useful when resin compatibility and efficient resin penetration are important production considerations.

2. Rapid Resin Impregnation

The open fiber structure allows resin to penetrate the stitched fiberglass mat efficiently.

The current product specification lists resin impregnation time of ≤60 seconds for the standard EMK series.

Rapid wet-out can help improve processing efficiency during hand lay-up,RTM,resin infusion,and other liquid resin molding processes.

3. Multidirectional Fiberglass Reinforcement

The chopped E-glass strands are randomly distributed throughout the reinforcement layer.

This provides reinforcement in multiple directions rather than concentrating fibers along only one orientation.

The structure makes fiberglass stitched mat suitable for FRP components requiring balanced reinforcement across complex shapes and laminate structures.

4. Stable Handling During Composite Manufacturing

Polyester stitching yarn mechanically stabilizes the chopped glass fibers,helping the mat maintain its structure during cutting,handling,positioning,and resin impregnation.

This can make the material easier to process in applications where loose fiber movement or mat deformation needs to be controlled.

5. High-Strength Composite Reinforcement

Glass fiber stitched mat is designed for structural FRP and composite applications requiring reliable fiberglass reinforcement.

Different grammages can be selected according to laminate thickness,mechanical requirements,and final component design.

Heavier grades such as EMK600 and EMK900 are available for structural and heavy-duty composite applications.

6. Multiple Resin Compatibility

The stitched fiberglass structure is suitable for commonly used thermoset composite resin systems,including:

• Unsaturated Polyester Resin (UP)

• Vinyl Ester Resin (VE)

• Epoxy Resin (EP)

Actual resin compatibility should be confirmed according to the selected grade,stitching system,and manufacturing process.

7. Multi-Process Compatibility

Glass fiber stitched mat can be used in several FRP manufacturing processes.

Depending on the selected specification,applications include:

• Hand Lay-Up

• RTM

• Resin Infusion

• Pultrusion

• Filament Winding

This provides composite manufacturers with a versatile fiberglass reinforcement option for different production methods.

8. Flexible Grammage and Width Customization

Standard EMK grades cover multiple grammages from 225–900 g/m².

Customized products can be supplied according to required grammage,width,reinforcement structure,and final application.

Widths up to 3600 mm and grammages up to 1200 g/m² can be evaluated according to customer requirements.

Glass Fiber Stitched Mat Applications

1. Marine & Boat Building

Fiberglass stitched mat can be used as reinforcement in selected marine composite structures,including FRP hulls,decks,bulkheads,and pipe linings.

The combination of random chopped fibers and mechanical stitching provides multidirectional reinforcement while maintaining good handling characteristics during laminate production.

Different grammages can be selected according to the required marine laminate structure.

2. FRP Pipes & Pipe Linings

Selected stitched mat grades can be incorporated into FRP pipes and pipe lining systems.

The material can provide an additional multidirectional reinforcement layer and can be used with suitable resin systems according to the chemical environment and pipe construction requirements.

3. FRP Tanks & Chemical Equipment

Glass fiber stitched mat can be used in composite tanks,cooling towers,and selected chemical equipment.

Vinyl ester or other appropriate resin systems can be selected according to the chemical exposure and corrosion-resistance requirements of the finished composite structure.

4. Automotive & Transportation Components

Fiberglass stitched mat can be used for selected automotive panels,bumpers,interior composite structures,and transportation components.

Its mechanically stabilized fiber structure makes it suitable for molded composite parts requiring efficient material handling and multidirectional reinforcement.

5. Pultruded Composite Profiles

Selected stitched mat grades are suitable for pultrusion applications.

The mat can be combined with continuous fiberglass reinforcement to provide additional transverse or multidirectional reinforcement within pultruded profiles.

Typical applications can include industrial profiles,structural sections,and other continuous FRP components.

6. Structural FRP Components

Higher-grammage stitched mats can be used in selected structural composite applications where additional reinforcement thickness and multidirectional fiber distribution are required.

Applications can include industrial panels,equipment housings,structural FRP components,and other heavy-duty composite products.

7. Wind Energy & Industrial Composites

Selected heavier grades can be used in composite structures associated with wind energy and industrial equipment.

Actual material selection should be based on laminate design,resin system,mechanical requirements,and manufacturing process.

Technical Specifications by Grade

Actual product specifications should be selected according to manufacturing process,resin system,laminate structure,mechanical requirements,and final application.

Resin Compatibility

Because this product uses mechanical stitching rather than a conventional chemical binder,the reinforcement structure provides good resin accessibility.

Actual resin selection should still be based on the manufacturing process,final application,and required laminate performance.

Manufacturing Processes

1. Hand Lay-Up

Glass fiber stitched mat can be used in hand lay-up applications where stable handling and multidirectional fiberglass reinforcement are required.

The mechanically stitched structure helps keep the chopped fibers together during cutting,positioning,and resin impregnation.

EMK225 is one of the available grades suitable for hand lay-up applications.

2. Resin Transfer Molding (RTM)

Selected stitched mat grades can be used in RTM applications.

The open fiberglass structure allows liquid resin to penetrate the reinforcement while the stitching helps maintain fiber distribution during mold loading and resin injection.

3. Resin Infusion

Fiberglass stitched mat can be considered for selected resin infusion applications where resin flow,reinforcement stability,and multidirectional fiber distribution are required.

Material selection should consider resin viscosity,laminate thickness,flow media,and infusion parameters.

4. Pultrusion

Selected stitched mat grades can be combined with continuous roving or other fiberglass reinforcement in pultruded composite profiles.

The mat provides additional reinforcement in directions not fully covered by longitudinal continuous fibers.

5. Filament Winding

Glass fiber stitched mat can be incorporated into selected filament winding structures for FRP pipes,tanks,and cylindrical composite components.

EMK300 is one of the grades listed for pultrusion and filament winding applications.

Hybrid Fiberglass Reinforcement Options

Hybrid structures combining chopped strand layers with woven roving can also be supplied for selected composite applications.

One example listed in the current product range is an EMK600/300 hybrid construction combining a chopped strand layer with woven roving reinforcement.

Hybrid fiberglass structures can be considered when the laminate requires both multidirectional chopped fiber reinforcement and stronger directional reinforcement from woven or continuous fibers.

Actual hybrid configuration should be selected according to laminate design,mechanical requirements,and manufacturing process.
