Fiberglass chopped strand mat is a non-woven fiberglass reinforcement material made from randomly distributed chopped glass fibers bonded together by a special binder.
It is widely used in FRP (Fiber Reinforced Plastic) manufacturing because it provides excellent resin absorption, easy molding performance, and good surface finishing.
The main types of chopped strand mat include powder binder mat and fiberglass chopped strand mat emulsion, which are designed for different resin systems and applications.
Chopped strand mat is commonly supplied in roll form, known as fiberglass chopped strand mat roll, with different weights such as 225g/m², 300g/m², 450g/m², and 600g/m².
Yes, you can touch fiberglass mat, but appropriate protective measures are recommended during handling.
Fiberglass fibers are very fine and may cause temporary skin irritation upon direct skin contact.
When handling chopped strand mat, it is recommended to wear:
Protective gloves
Long-sleeved clothing
Safety glasses when cutting or processing.
High-quality chopped strand mat has a stable fiber structure and produces less fiber shedding during normal operation.
Yes, chopped strand mat can be used with epoxy resin, but customers should select the correct type.
Traditional chopped strand mat is usually designed for polyester and vinyl ester resin systems. Some standard mats may not perform well with epoxy because the binder may not dissolve properly.
For epoxy applications, it is better to choose:
The correct combination of resin and fiberglass reinforcement ensures better strength, bonding performance, and product durability.
The required layers of chopped strand mat depend on the product design, thickness requirement, and final strength needed.
Common applications use different layer structures:
For example, boat manufacturing, FRP tanks, and industrial equipment usually require multiple layers of fiberglass chopped strand mat to achieve better impact resistance and structural strength.
The correct number of layers should be determined according to the final application requirements.
In most wet lay-up applications, sanding between fiberglass layers is not always required.
If the next layer is applied while the previous resin layer is still chemically active, the layers can bond directly together.
However, sanding may be recommended when:
Before adding another layer of chopped strand mat, cleaning and surface preparation are important to achieve strong adhesion.
Emulsion binder chopped strand mat usually offers:
Powder binder mat usually provides:
