炭素繊維強化鋼構造物の表面処理はどのように行うか?

Steel Surface Preparation Steps: 1. Marking: Define the area where carbon fiber sheets are to be applied. 2. Grinding: Grind the marked steel surface to achieve flatness and remove rust or oxides. Begin with coarse sandpaper to smooth the surface, applying even pressure. Finish with fine sandpaper in a cross-grinding pattern. 3. Cleaning: Use cotton balls soaked in alcohol or acetone to clean the application area, eliminate contaminants, and allow it to dry completely. 4. Adhesive Application: Prepare carbon fiber adhesive and evenly apply it to the steel substrate using a brush. 5. Carbon Fiber Sheet Installation: Place the carbon fiber sheet onto the steel substrate. Ensure the adhesive fully penetrates the sheet, allowing excess […]

炭素繊維の熱膨張係数を理解する:包括的ガイド

Understanding the Carbon Fibre Thermal Expansion Coefficient: A Comprehensive Guide Carbon fibre is a revolutionary material used in various industries, including aerospace, automotive, and sports equipment. One crucial property of carbon fibre that engineers and designers must consider is its thermal expansion coefficient (CTE). Understanding this concept is essential for ensuring the performance and durability of carbon fibre components under varying temperature conditions. What Is the Thermal Expansion Coefficient? The thermal expansion coefficient (CTE) measures how much a material expands or contracts when exposed to temperature changes. For carbon fibre, this coefficient is typically much lower than that of traditional materials like steel or aluminum. This property makes carbon fibre

なぜスポーツ用品製造業界はカーボンファイバー素材の採用に熱心なのか?

The Ideal Material for Lightweight and Labor-Saving Sports Bicycles Carbon fiber is the ideal material for lightweight and labor-saving sports bicycles. The creation of a carbon fiber bicycle frame involves an orderly process, including carbon filament weaving, carbon cloth cutting, and molding. After being woven and pressed under high pressure, carbon filaments form carbon cloth. When this cloth is cut, wrapped around core materials, and molded, it becomes the carbon fiber bicycle frame. Compared to aluminum alloy frames, carbon fiber frames are 30% lighter, helping athletes conserve energy during long-distance competitions. Benefits of Carbon Fiber in Sports Equipment: 1. Carbon fiber boasts exceptional properties such as high-temperature resistance, corrosion resistance,
