Technical Specifications

Chopped Strand Mat (CSM) is a widely used reinforcement material in composite applications, such as cable ladder, offering flexibility and strength in a variety of projects. The technical specifications of CSM, including area weight, roll width, and roll length, play a crucial role in determining its suitability for different applications. Below, we explore these key specifications in more detail to help guide your selection process.

Area Weight: Available in Weights Like 1 oz/ft², 1.5 oz/ft², and 3 oz/ft² for Different Applications

The area weight of CSM, often referred to as the weight per square foot, directly influences the strength, flexibility, and thickness of the material. The weight of the mat determines its application and suitability for various projects.

• 1 oz/ft²: This is one of the lightest weights available and is best suited for applications requiring flexibility and ease of handling. It’s commonly used for repairs, smaller components, and areas where minimal thickness is needed. It is ideal for applications that do not require heavy structural support but still need reinforcement, such as cosmetic parts or lightweight molds.
• 1.5 oz/ft²: This is one of the most common area weights used in the industry. It strikes a good balance between strength and flexibility, making it ideal for a variety of composite applications. The 1.5 oz/ft² weight is versatile and can be used for boat hulls, automotive parts, and general composite constructions. It is strong enough to provide structural support while still being easy to work with and conform to shapes.
• 3 oz/ft²: This heavier weight is designed for applications that require more rigidity and durability. The 3 oz/ft² mat is commonly used in larger, high-performance components, such as structural elements, pressure vessels, and parts exposed to higher levels of stress. It is also suitable for use in industrial applications, including cable ladders or other heavy-duty structural components. This weight offers increased strength and thicker laminates, making it ideal for projects that demand higher mechanical properties and impact resistance.

GangLong Fiberglass provides a variety of CSM options in different weights, including 1 oz/ft², 1.5 oz/ft², and 3 oz/ft², catering to a wide range of applications. Their products are designed to offer the right balance of strength and flexibility, ensuring optimal performance across various industries.

Roll Widths: Common Widths Include 38”, 41”, and 50”

The width of the Chopped Strand Mat roll is important because it determines how much material you can cover in one go. The right roll width helps reduce cutting and wastage, especially for larger projects or molds.

• 38”: This narrower width is often used for smaller applications, such as repairs or components that don’t require extensive coverage. It’s ideal for tight spaces and precise applications where exact dimensions are needed. Narrower rolls like 38” are often chosen when cutting smaller sections or when a more controlled application is necessary.
• 41”: The 41” width provides a moderate balance, offering more material coverage while still being manageable for various applications. This width is often used for projects that require slightly larger coverage but still need to be handled easily without being too bulky, making it a good choice for medium-sized components.
• 50”: The 50” roll width is commonly used in larger applications, providing a wider material coverage for bigger components or industrial projects. For large structures like cable ladders or boat hulls, the wider roll allows you to minimize cuts and handling time. It is perfect for applications requiring larger surface areas to be laminated in a shorter amount of time.

Roll Lengths: Rolls Are Typically Available in Lengths Ranging from 80 to 120 Yards, Depending on the Weight and Width

The length of the roll is another key specification to consider when selecting Chopped Strand Mat (CSM) for your project. The roll length determines how much material is available for your application and how many layers you can apply without needing to open a new roll. Additionally, the choice of roll length can affect how efficiently you can combine CSM with other materials like fiberglass sheets for enhanced strength and durability.

• 80 Yards: Rolls with a length of 80 yards are often preferred for smaller projects or applications that require less material. For example, smaller repairs or limited-use components may only require shorter lengths of CSM. This shorter roll length helps reduce waste and ensures that you don’t over-purchase material for smaller jobs.
• 100 Yards: 100-yard rolls are a good middle ground for many applications, providing a reasonable length for most typical composite projects. This length works well for medium-sized components, such as automotive parts or smaller structural elements like beams and panels, where a substantial amount of CSM is needed but not in excessive quantities.
• 120 Yards: The longest roll length, 120 yards, is ideal for large projects or industrial-scale applications where significant amounts of material are required. For large molds, extensive construction, or multiple layers in projects like cable ladders, 120-yard rolls offer the convenience of purchasing in bulk, reducing the need for frequent roll changes and minimizing interruptions during the application process.
