As a leading fiberglass manufacturer with two decades of industry expertise, Hebei YUNIU Technology Co., Ltd. has consistently delivered innovative solutions that redefine composite material standards. Our fiberglass chopped strand mat (CSM) stands at the forefront of reinforcement technology, engineered to elevate the mechanical properties of composites across industries. From automotive components to marine structures, our CSM products combine precision manufacturing with unmatched performance, making us the preferred choice for 3,162 customers in 128 countries.
Composite materials have revolutionized modern manufacturing, but achieving optimal reinforcement remains a critical challenge. Traditional reinforcement methods often struggle to deliver uniform strength, leading to inconsistent product quality and limited design flexibility. Manufacturers face trade-offs between tensile strength, impact resistance, and processability—until now.
Our chop strand mat fiberglass addresses these pain points head-on. By combining randomly oriented fiberglass strands with a specialized binder, we’ve created a reinforcement solution that offers:
• Isotropic Strength: Uniform performance in all directions, eliminating weak spots.
• Moldability: Adaptability to complex shapes without delamination.
• Cost Efficiency: Reduced material waste and labor costs compared to woven fabrics.
Chopped glass fiber strands form the core of our CSM, with each strand precision-cut to lengths ranging from 6mm to 50mm. These strands are randomly distributed and bonded with a thermosetting resin binder, creating a mat that:
• Distributes Stress Uniformly: The random orientation ensures even load distribution, critical for components subjected to multi-directional forces.
• Enhances Impact Resistance: The discontinuous fiber structure absorbs energy, reducing crack propagation.
• Facilitates Easy Processing: The mat’s flexibility allows it to conform to intricate molds, ideal for hand lay-up, spray-up, and compression molding processes.
• Boat Hulls & Decks: Our chopped mat reinforces fiberglass-reinforced plastic (FRP) hulls, improving impact resistance against waves and reducing water absorption.
• Offshore Structures: Used in oil platform components, our CSM withstands saltwater corrosion and high mechanical stress.
• Body Panels & Underbody Components: Lightweight yet strong, our CSM reduces vehicle weight by 30% while maintaining crash resistance.
• Bus & Train Interiors: Fire-retardant CSM variants meet strict safety standards for public transportation.
• Prefabricated Concrete Elements: Reinforces concrete pipes, manholes, and architectural panels, preventing cracking and extending service life.
• Blast-Resistant Barriers: Military-grade CSM provides ballistic protection in security installations.
• Chemical Tanks & Vessels: Corrosion-resistant CSM withstands harsh chemicals in pharmaceutical and petrochemical plants.
• Wind Turbine Components: Enhances the durability of blade root sections, enduring constant rotational stress.
• State-of-the-Art Facilities: Our automated needle-punching lines in Shijiazhuang and Thailand maintain fiber weight tolerance within ±3%, ensuring consistent performance batch after batch.
• Binder Innovation: Proprietary polyester and vinyl ester binders offer superior wet-out properties, reducing resin consumption by 15%.
• Customized Solutions: From 300gsm to 2400gsm mat weights, we tailor CSM specifications to your exact requirements. Need UV-resistant binders for outdoor applications? We’ve got you covered.
• Rigorous Testing: Every batch undergoes:
◦ Tensile strength testing (ASTM D638: ≥300MPa)
◦ Bend resistance (ISO 14125: no cracking at 180°)
◦ Water absorption (ASTM D570: <0.2% after 24h)
