An article to understand the application of carbon fiber in the field of rail transit
Relevant data show that by 2025, the mileage of China's high-speed rail will exceed 38,000 kilometers, and there will be more than 2,500 high-speed trains in service. The energy saving, environmental protection, comfort and convenience of trains have become the future development direction of high-speed trains. Because of its excellent performance, carbon fiber has attracted more and more attention and adoption by rail vehicle development enterprises, and has huge development potential.

Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
Choosing the right abrasion testing equipment is essential for obtaining accurate and repeatable wear resistance results. DIN Abrasion Tester and Taber Abrasion Tester are two widely used abrasion testing machines, but they are designed for different material types and testing purposes.
This article provides a detailed comparison between DIN Abrasion Tester and Taber Abraser, covering their working principles, specimen requirements, industry applications, standard compliance, technical characteristics, operation features and practical advantages. DIN Abrasion Tester is mainly designed for rubber, elastic materials, tires, conveyor belts and footwear soles, while Taber Abrasion Tester is suitable for flat materials such as coatings, textiles, plastics, leather, metals and decorative surfaces.
By understanding the differences between these two abrasion testing methods, laboratories can select the most suitable abrasion tester based on sample geometry, testing standards and production quality control requirements.
The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
