Why Binderless Chopped Strand Mat is a Game Changer
Production Process of O Continuous and Chopped Strand Mats
The production process of O continuous and chopped strand mats involves several stages, each tailored to produce the desired material characteristics. Understanding these processes helps to highlight the advantages and differences between continuous strand mats and chopped strand mats. These materials are created using distinct manufacturing techniques that impact their performance, cost, and suitability for various applications.
Manufacturing Continuous Filament Mats
- Process of Laying Down Continuous Strands and Applying Binders:
The production of O continuous and chopped strand mats begins with the creation of continuous glass filaments. Molten glass is extruded through fine nozzles, forming long, continuous strands. These strands are then randomly laid down onto a moving conveyor belt. The fibers are spread evenly, ensuring a consistent mat structure.- A binder is applied to hold the fibers together. The binder is often a resin or polymer that provides adhesion without compromising the flexibility or strength of the mat.
- The mat is formed by layering continuous strands in different orientations to create a mat that is both strong and flexible.
- Trimming, Rolling, and Final Product Characteristics:
Once the continuous strands are laid down and the binder is applied, the mat undergoes trimming to ensure the proper size and shape. The mat is then rolled for easy storage and transport. The final product is a continuous filament mat that offers enhanced strength and durability.- Characteristics:

Production of Chopped Strand Mats
- Fiber Cutting and Distribution for Chopped Strand Mats:
The production of O continuous and chopped strand mats differs from that of continuous filament mats in the fiber length and production technique. Instead of long strands, the glass fibers are cut into short lengths, typically ranging from 1 to 4 inches (2.5 to 10 cm). These chopped fibers are randomly distributed onto a moving conveyor, creating a non-woven mat structure.- A binder is applied to the chopped fibers to keep them together during the handling process. The binder also ensures the mat maintains its integrity when it is used in manufacturing or molding processes.
- The chopped strand mat is then pressed, trimmed, and rolled to form the final product. This process is less complex than continuous filament mat production, making chopped strand mats more cost-effective.
- Differences in Production Between Chopped Strand and Continuous Mats:
While both O continuous and chopped strand mats are made from glass fibers, their production methods are distinct.- Fiber Length:

FAQs about O Continuous and Chopped Strand Mats
The main difference between continuous filament mat and chopped strand mat lies in the fiber length and structure. Continuous filament mats use long, continuous glass fibers that are randomly oriented. These fibers provide superior strength, making the mats suitable for structural applications that require high durability. In contrast, chopped strand mats consist of shorter, cut glass fibers that are also randomly oriented. These mats are more flexible and are commonly used for mold filling and non-structural applications. Continuous filament mats offer higher tensile strength and are often used in demanding processes like resin transfer molding and vacuum infusion. Chopped strand mats, however, are more cost-effective and easier to handle, making them ideal for high-volume production where strength requirements are less critical.
Chopped strand mat offers several advantages, especially in terms of flexibility, cost-effectiveness, and ease of handling. Since chopped strand mats are made of short glass fibers, they are easier to handle and conform to irregular mold shapes. This makes them ideal for complex or large mold cavities. Additionally, chopped strand mats are cost-effective compared to continuous filament mats. They are less expensive to produce, which makes them a popular choice for high-volume manufacturing. Despite their lower strength compared to continuous filament mats, chopped strand mats are still durable and offer good resistance to wear and tear. They are commonly used in non-structural applications such as automotive body panels, boat hulls, and general-purpose composites. Their ability to fill mold cavities smoothly and uniformly makes them a reliable choice for many composite manufacturers.
Chopped strand matting refers to a type of non-woven fiberglass fabric made from short strands of glass fibers that are randomly distributed. The fibers are typically 1 to 4 inches in length and are bound together with a resin or binder to form a mat. Chopped strand mats are used extensively in composite manufacturing processes such as molding, where the mat is laid down in the mold before being infused with resin. This matting provides reinforcement for the composite material, enhancing its strength and durability. The random fiber orientation gives the material flexibility and the ability to conform to complex mold shapes, making it ideal for use in vacuum infusion and resin transfer molding processes. Chopped strand matting is popular in various industries such as automotive, marine, and construction, where lightweight and durable composite materials are needed.
Chopped strand mat and woven roving are both used in composite manufacturing, but they differ in their structure and intended uses. Chopped strand mats are made of randomly oriented, short glass fibers, while woven roving consists of continuous glass fibers that are woven into a fabric pattern. The key difference is that woven roving offers higher tensile strength due to the continuous fibers and their woven structure. This makes woven roving ideal for applications that require high strength, such as structural reinforcement in boats and automotive components. In contrast, chopped strand mats are more flexible and suitable for filling mold cavities and creating smooth surface finishes. While woven roving is often used in combination with other materials for structural laminates, chopped strand mats are commonly used for less demanding applications where ease of handling and cost-effectiveness are more important.
