- Good mechanical properties: It offers good strength, rigidity, and impact resistance when used with fiber reinforcements like Chopped Strand Mat (CSM).
Benefits of Using CSM with Polyester Resin
- Strength and Durability: Polyester resin impregnates the glass fibers in CSM to form a strong, rigid composite material. This provides the final product with good tensile strength, flexural strength, and impact resistance.
- Good Surface Finish: Polyester resin provides a smooth, glossy finish, especially when used with lighter weights of CSM, making it ideal for aesthetic applications.
- Cost-Effectiveness: Polyester resin is one of the most economical resin choices, and CSM is typically less expensive than other reinforcements like woven fabrics or unidirectional tapes.
- Quick Curing Time: Polyester resin cures faster than other resins (like epoxy), allowing for faster production and turnover times in manufacturing.
- Ease of Application: Polyester resin is easy to apply and has good wetting properties, ensuring that it penetrates and bonds well with the CSM fibers.
Application Process
The process for using Chopped Strand Mat (CSM) with polyester resin generally involves the following steps:
Preparation
Clean the mold or surface thoroughly, removing dust, grease, or oil. Apply mold release wax if needed for easier demolding. Cut the Chopped Strand Mat (CSM) to the required size according to the project’s specifications. Proper preparation ensures better resin bonding, smooth curing, and easy part removal, reducing defects and saving time during later stages of the fiberglass lamination process.
Mixing the Resin
Combine polyester resin with MEKP catalyst at 1–2% by weight, following manufacturer instructions. Mix thoroughly but avoid excessive air bubbles. Be mindful of the limited working time—polyester resin cures quickly, often within minutes. Prepare only the amount you can apply within the pot life to ensure proper wet-out and avoid wasted material during the lamination process.
Laying Down the Mat
Apply a layer of resin to the mold or surface using a brush, roller, or spray gun. Place the CSM over the wet resin and press gently to ensure full contact. Add more resin as needed to saturate fibers. Continue layering CSM and resin, rolling each layer to remove air bubbles, ensuring uniform saturation and strong bonding between layers for structural integrity.
Curing
Allow the laminate to cure undisturbed. At room temperature, polyester resin typically cures in 1–2 hours. Cure time varies with temperature, layer thickness, and resin type. Heat can accelerate curing, but avoid excessive temperatures. For thicker parts, optional post-curing can improve mechanical properties, strength, and heat resistance, especially for components subject to heavy loads or high-stress environments.
Demolding and Finishing
Once fully cured, carefully remove the part from the mold to avoid damage. Trim excess material, sand rough edges, and perform additional finishing as required, such as painting or polishing. Proper finishing improves appearance and surface smoothness while preparing the part for functional use, whether in marine, automotive, or structural fiberglass applications.
Considerations When Using CSM with Polyester Resin
- Ventilation and Safety: Polyester resin and its catalyst (MEKP) release fumes during the curing process, so ensure that the workspace is well-ventilated and that proper personal protective equipment (PPE) is used (gloves, respirators, goggles).
- Exothermic Reaction: Polyester resin undergoes an exothermic reaction when curing (it generates heat). Ensure that the application area can dissipate heat, especially for thicker layers or large parts.
- Resin Saturation: Proper resin saturation of the CSM is essential for achieving good strength. Insufficient resin can result in weak spots, while excessive resin can add unnecessary weight.
- Gel Coat: For visible parts (like boat hulls or automotive panels), a gel coat may be applied to provide a glossy, smooth surface finish and additional protection.
Using Chopped Strand Mat (CSM) with polyester resin is an effective and cost-efficient method for producing a variety of fiberglass-reinforced composite materials. It offers good strength and durability for applications in industries like marine, automotive, construction, and industrial equipment. By following proper application procedures and safety precautions, CSM and polyester resin can be combined to create high-performance, lightweight, and cost-effective composite structures.

Length: Chopped fibers are short lengths of fibers, typically a few millimeters to several inches long. These fibers are often randomly oriented and used in non-woven mats or as fillers in composite materials.
Strength: Provides more uniform but lower strength compared to continuous fibers. Chopped fibers are used to add bulk, improve surface finish, and provide reinforcement in multiple directions.
Applications: Used in chopped strand mats, fillers, and as reinforcements in injection molding and other composite applications where complex shapes are involved and directional strength is less critical.
What is the difference between continuous filament mat and chopped strand mat?
Structure: Made from long, continuous glass fibers that are randomly laid and bound together with a binder. The continuous fibers provide better strength and consistency compared to chopped fibers.
Strength: Generally stronger and more uniform than chopped strand mat due to the uninterrupted length of the fibers.
Flexibility: More flexible than chopped strand mat, making it easier to conform to complex shapes.
Chopped Strand Mat (CSM):
Structure: Made from short, chopped glass fibers that are randomly oriented and held together with a binder. The fibers are typically 1-2 inches in length.
Strength: Provides uniform strength in all directions, but it is generally less strong than continuous filament mat due to the shorter fiber lengths.
Flexibility: Less flexible than continuous filament mat, but still capable of conforming to moderately complex shapes.
What is the difference between chopped and continuous fiber?
Length: Short fibers, typically a few millimeters to several inches long.
Strength: Offers uniform strength in all directions but is generally weaker than continuous fiber due to the shorter length.
Applications: Used in non-woven mats, fillers, and composite materials where multi-directional reinforcement is needed.
Continuous Fiber:
Length: Long, unbroken strands of material that provide high tensile strength.
Strength: Superior strength, especially in the direction of the fibers, due to the continuous nature of the material.
Applications: Used in woven fabrics, reinforcement materials for composites, and other applications where high strength and rigidity are required.
What is a continuous filament mat used for?
Composite Layups: For creating strong, lightweight composite structures.
Automotive and Aerospace Parts: Where uniform strength and stiffness are crucial.

What is the difference between a cutting mat and a self healing cutting mat?
Surface: Typically made from hard plastic or rubber, offering a protective surface for cutting but can show cuts and wear over time.
Durability: Cuts made on a standard cutting mat may remain visible, leading to a worn surface.
Applications: Suitable for general cutting tasks but may not last as long as self-healing mats.
Self-Healing Cutting Mat:
Surface: Made from multiple layers of specialized materials that allow the mat to ""heal"" itself after being cut. The surface closes up small cuts, maintaining a smooth surface.
Durability: Lasts longer as the surface remains smooth and free from permanent grooves, even after repeated use.
Applications: Ideal for frequent cutting tasks, such as quilting, crafting, and precision work, where a smooth, long-lasting surface is needed.
What is the difference between chopped and woven carbon fiber?
Structure: Made from short carbon fibers that are randomly oriented.
Strength: Offers uniform strength in all directions but is generally less strong than woven carbon fiber.
Applications: Used as a filler or in non-woven mats for applications requiring multi-directional reinforcement.
Woven Carbon Fiber:
Structure: Made from continuous carbon fibers woven into a fabric. The weave pattern can vary, providing different levels of flexibility and strength.
Strength: Provides higher strength and rigidity, especially along the direction of the fibers.
Applications: Used in high-performance applications, such as aerospace, automotive, and sporting goods, where maximum strength and low weight are critical.
Which carpet fiber type is a continuous strand?
What is the difference between a staple Fibre and a continuous filament Fibre?
Length: Short fibers that are typically a few inches long.
Structure: Need to be spun into yarns, resulting in a fabric that can be soft and fluffy but might shed fibers.
Applications: Used in textiles like cotton or wool fabrics, where softness and comfort are important.
Continuous Filament Fiber:
Length: Long, continuous strands of fiber that can be woven directly into fabric.
Structure: Results in a smoother, stronger, and more durable fabric with less shedding.
Applications: Used in high-performance textiles, such as those made from nylon, polyester, or silk, where durability and a smooth finish are desired.
What is the difference between fiberglass cloth and mat?
Structure: Made from continuous glass fibers woven into a fabric. The weave pattern can vary, providing different levels of flexibility and strength.
Strength: Offers higher tensile strength and is used for structural reinforcement.
Applications: Used in applications requiring high strength and a smooth finish, such as boat building, automotive panels, and aerospace components.
Fiberglass Mat (Chopped Strand Mat):
Structure: Made from short, randomly oriented glass fibers held together by a binder.
Strength: Provides uniform strength in all directions but is generally less strong than fiberglass cloth.
Applications: Used to build thickness and provide bulk in composite layups, as well as to smooth surfaces and reinforce complex shapes.
What is chopped strand matting?
What is the difference between vinyl and rubber ESD mat?
Material: Made from vinyl, a synthetic plastic polymer.
Durability: Generally less durable than rubber but lighter and easier to clean.
Applications: Commonly used in electronics manufacturing, assembly lines, and areas where static control is important but heavy wear is not expected.
Rubber ESD Mat:
Material: Made from natural or synthetic rubber.
Durability: More durable and resistant to wear and chemicals than vinyl, making it suitable for heavy-duty environments.
Applications: Used in environments where both static control and durability are critical, such as in laboratories, industrial settings, and areas with heavy foot traffic.
What is the difference between filament tape and strapping tape?
Structure: Reinforced with continuous filaments (usually fiberglass) embedded in the tape, providing high tensile strength and resistance to tearing.
Applications: Used for bundling, reinforcing, and securing heavy items. Commonly used in packaging and shipping to secure boxes and pallets.
Strapping Tape:
Structure: Typically made from polypropylene or polyester, without the embedded filaments. It provides good tensile strength but is less resistant to tearing compared to filament tape.
Applications: Used for bundling and securing lighter packages and materials. It’s often used in situations where the tape needs to be cut easily or where extreme strength is not required.
