Fiberglass chopped strand mat is made of randomly distributed chopped glass strands held together by a powder or emulsion binder. Widely applied to FRP boat, bath equipment, automobile, chemical tank, cooling tower, and furniture, etc.

Properties of Fiberglass Chopped Strand Mat

Powder

1. Excellent weight uniformity

2. High tensile strength

3. Great wet-through and fast wet-out in resins, rapid airlease, stiffer than emulsion

4. High mechanical strength of parts

5. Excellent transparency of finished products

6. Excellent laminate clarity

Emulsion

1. Excellent weight uniformity

2. No flying objects during operation

3. Good wet-through and fast wet-out in resins, softer than powder

4. High mechanical strength of parts

5. Excellent transparency of finished products

6. Excellent laminate clarity

FAQs

Q₁: How does it differ from woven roving or fiberglass cloth?

A: Fiberglass chopped strand mat has short, random fibers, making it flexible, easy to shape, and impact-resistant, while woven cloth has continuous fibers, offering higher strength along fiber directions but less flexibility.

Q: How resistant is it to heat, chemicals, or moisture?

A: Fiberglass chopped strand mat is generally resistant to heat, most chemicals, and moisture, though its exact resistance depends on the type of glass fiber (like E-glass or S-glass) and the resin used in the composite.

Q: Which molding methods are suitable for CSM?

A: Chopped strand mat is suitable for hand lay-up, spray-up, vacuum bagging, and resin transfer molding, thanks to its flexibility and ability to absorb resin easily.

Q: How can you evaluate the quality of chopped strand mat?

A: The quality of chopped strand mat can be evaluated by checking fiber length and uniformity, mat weight (gsm), binder distribution, tensile strength, thickness consistency, and how well it wets out with resin.

QWhat are the common weaknesses of CSM in composite structures?

A: Common weaknesses of chopped strand mat include lower tensile and flexural strength compared to woven fabrics, less dimensional stability, higher resin consumption, and potential for air entrapment or surface roughness in molded parts.
