300g Fiberglass Chopped Strand Mat

300g Fiberglass Chopped Strand Mat is a nonwoven E-Glass reinforcement material with an area weight of 300 g/m². The chopped glass fibers are randomly distributed and bonded into a continuous mat, allowing the material to conform to molded surfaces and contribute reinforcement across multiple directions within a laminate.

With a 300 g/m² area weight, the material sits between lighter and heavier mat specifications commonly used in composite manufacturing. It can be incorporated into single or multiple reinforcement layers according to the required laminate thickness, resin system, mold geometry and finished-part requirements.

For production, the mat can be cut, positioned and combined with other reinforcement materials before resin application. The final laminate structure should be determined according to the design and processing method rather than area weight alone.

Where 300 g/m² Chopped Strand Mat Is Used

Boat Manufacturing

Used in selected hulls, decks and molded sections where chopped strand reinforcement forms part of a multi-layer laminate.

FRP Pipes and Tanks

Can be incorporated into layered composite structures for pipes, storage tanks and corrosion-resistant equipment.

Sanitary Ware

Applied in molded fiberglass products with curved or irregular surfaces, including baths and other sanitary components.

Cooling Towers

Used as one of the fiberglass reinforcement layers in selected cooling tower and related FRP components.

Automotive and Building Components

Used for selected molded FRP parts where a 300 g/m² reinforcement layer fits the specified laminate construction.

Random Fiber Structure for Laminate Reinforcement

Unlike woven roving, which has defined fiber directions, chopped strand mat consists of randomly dispersed short glass fibers. This structure provides reinforcement without establishing a single dominant fiber direction.

The material can be cut into sections, overlapped and combined with woven fabrics or other reinforcement products as part of a laminate schedule. Its flexible sheet structure also makes it easier to position around curves, corners, transitions and other molded contours.

The contribution of the mat to the finished composite depends on the complete laminate design, including fiber content, resin ratio, reinforcement sequence, curing conditions and manufacturing process.

Resin Compatibility

The 300g Fiberglass Chopped Strand Mat from Yuruis is listed as compatible with the following resin systems:

·  Unsaturated Polyester (UP) Resin

·  Vinyl Ester (VE) Resin

·  Epoxy (EP) Resin

·  Phenolic (PF) Resin

The resin should be selected according to the finished product, curing process, service environment and required chemical or mechanical performance. Resin compatibility should also be confirmed for the specific production process before regular manufacturing.

FAQ

Is 300g chopped strand mat suitable for hand lay-up?

Yes. The material can be cut and positioned according to the mold shape, making it suitable for hand lay-up applications where the selected laminate design calls for chopped strand mat.

What products can use 300g mat?

Typical applications include boats, FRP pipes and tanks, sanitary ware, cooling tower components and selected automotive and building parts.

Can it be combined with woven roving?

Yes. Chopped strand mat and woven roving can be combined when the laminate requires both randomly distributed reinforcement and reinforcement with defined fiber directions.

Can the width be customized?

Yes. Customized widths are available according to production requirements. The required width should be confirmed together with the mold dimensions, laminate layout and expected quantity.

Which resin systems are compatible?

UP, VE, EP and PF resin systems are listed as compatible. The final resin should be selected according to the application, curing conditions and service environment.

What is the standard roll length?

The listed reference roll length is 96 meters, with other requirements subject to production confirmation.
