What is Fiberglass Chopped Strand Mat​

Fiberglass chopped strand mat is a non-woven reinforcement fabric made from chopped fiberglass strands randomly distributed and held together by a binder, typically either powder or emulsion-based. Known for its excellent durability, strength, and ease of use, it is a critical component in the production of fiber-reinforced plastics (FRP) used in various industries, such as marine, automotive, construction, and more.

YONGXING Fiberglass, one of China’s premier chopped strand mat fiberglass manufacturers, offers top-quality products at factory-direct pricing, tailored to meet a wide range of specifications and project requirements.

Raw Materials

The primary material used in the production of fiberglass chopped strand mat is E-glass (electrical-grade glass fiber). E-glass is known for its superior insulating properties, corrosion resistance, and high tensile strength. The fiberglass is produced by melting raw materials, such as silica sand, alumina, calcium carbonate, and boron oxide, at high temperatures, followed by a process where the molten glass is pulled into fine strands.

Manufacturing Process

1. Chopping of Glass Fibers: During the production of fiberglass chopped strand mat, continuous glass fibers are chopped into specific lengths (usually 50mm) to form chopped fiberglass strands.
2. Distribution and Forming: These chopped strands are randomly distributed to create a mat, ensuring a multi-directional reinforcement. This randomness allows the mat to provide strength and stability in all directions.
3. Bonding: The distributed strands are then held together using either a powder binder or an emulsion binder, depending on the desired end-use. Powder binder mats are preferred for dry applications, while emulsion binder mats are easier to wet out with resins.
4. Cutting and Packing: The final mats are rolled into different sizes and weights, typically ranging from 100 g/m² to 900 g/m², based on customer requirements.

Key Technical Parameters

• Fiber Length: Standard chopped strands are usually around 50mm in length, though custom lengths are available upon request.
• Binder Type: Options include powder or emulsion binders, each suited to different resin systems and applications.
• Weight: Available in weights ranging from 100 g/m² to 900 g/m², with the ability to customize based on project needs.
• Resin Compatibility: Fiberglass chopped strand mat is compatible with a wide range of resin systems, including polyester, vinyl ester, and epoxy. This flexibility makes it suitable for hand lay-up, vacuum infusion, and spray-up processes.
• Thickness: Customizable thickness options allow for tailored reinforcement strength and surface finishes depending on the complexity of the project.

Benefits of Fiberglass Chopped Strand Mat

1. High Strength-to-Weight Ratio: Provides exceptional strength while keeping the composite structure lightweight, making it ideal for applications requiring both durability and weight reduction.
2. Excellent Corrosion Resistance: E-glass fibers used in chopped strand mats resist moisture and chemicals, ensuring long-lasting performance in harsh environments.
3. Ease of Use: The material wets out quickly and evenly with resin, making it easy to work with and perfect for rapid production cycles.
4. Dimensional Stability: Provides excellent structural stability, preventing warping or deformation, even under mechanical stress or exposure to environmental elements.
5. Multi-Directional Reinforcement: The random arrangement of chopped strands allows the mat to distribute mechanical loads evenly across all directions, enhancing the overall integrity of the finished composite.

Applications

Fiberglass chopped strand mat is utilized in a wide array of industries, owing to its adaptability and strength:

• Marine Industry: Used in the manufacturing of boat hulls, decks, and marine structures for its lightweight and corrosion resistance.
• Automotive Industry: Widely used in the production of exterior and interior panels, bumpers, and other structural components, offering significant weight savings while maintaining strength.
• Construction: Commonly used in the reinforcement of roofing panels, wall claddings, and water tanks, offering durability and thermal insulation.
• Waterproofing: Plays a key role in enhancing waterproof membranes in buildings and pools.
• Wind Energy: Used in the production of wind turbine blades, contributing to the overall structural strength while minimizing weight.
