100g Fiberglass Chopped Strand Mat

For thin laminates, excessive mat weight can make it harder to control the final thickness and may require additional resin and processing time. A 100g Fiberglass Chopped Strand Mat offers a more manageable layer when the production objective is surface coverage, localized reinforcement or gradual build-up through multiple thin layers.

Key benefits include:

·  Lightweight reinforcement for thin composite structures

·  Good conformability around curves, corners and irregular surfaces

·  Random fiber distribution for multidirectional reinforcement

·  Easy layer-by-layer build-up when a controlled laminate thickness is required

· Compatible with UP, VE and EP resin systems 

· Suitable for cutting and customized widths

· Moisture content controlled at ≤0.2% 

· Available for different composite manufacturing requirements

100g vs. Other Fiberglass Chopped Strand Mat Weights

Choosing the right CSM weight depends largely on the required laminate thickness, reinforcement level and forming method.

Where 100g CSM Makes Sense

Think of 100g CSM as a fine reinforcement layer rather than a bulk reinforcement material. It can be considered for thin FRP sheets, lightweight molded components, surface reinforcement, small composite parts and areas where the laminate needs to follow a complicated contour without excessive material buildup.

It is also useful when manufacturers prefer to construct a laminate progressively, combining several lighter layers rather than relying on one heavy mat.

Manufacturing and Custom Supply

The chopped strands are randomly distributed to form a continuous mat and bonded with a powder binder. During composite processing, the mat is impregnated with the selected resin and integrated into the laminate.

Yuruis can supply different CSM weights and widths according to production requirements. Standard production includes 100g, 150g, 225g, 300g, 450g and 600g/m², while customized specifications can be discussed according to the customer's forming process and laminate design.

FAQ

Is 100g CSM suitable for structural FRP?

It can be used as part of a structural laminate, but the final structural performance depends on the complete laminate design rather than the mat weight alone.

Why choose 100g instead of 300g CSM?

100g is easier to use where thin layers, surface conformity and controlled laminate buildup are more important than rapid thickness buildup.

Can 100g CSM be used with epoxy resin?

Yes. The supplied material can be used with epoxy, unsaturated polyester and vinyl ester resin systems, subject to process compatibility.

Can the width be customized?

Yes. Standard width is around 1.04m, while other widths can be discussed for production requirements.

Is 100g CSM available for OEM orders?

Yes. Weight, width, roll configuration and other production specifications can be customized according to order requirements.

What industries use lightweight CSM?

Typical applications include lightweight FRP panels, automotive composite parts, marine components, sanitary products and other molded composite products.
