温度変化は炭素繊維圧縮成形の結果にどう影響するか?

The three popular molding techniques for carbon fiber products include compression molding, autoclave molding, and filament winding. Among these, carbon fiber products shaped through compression molding showcase superior surface quality and are extensively utilized across various industries. The molding temperature during compression molding significantly influences the melting and flow of carbon fiber materials and the crosslinking reaction rate of the resin, ultimately impacting the overall quality of carbon fiber products. Within an optimal temperature range, an increase in mold temperature accelerates the flow of resin in carbon fiber prepregs and the crosslinking and curing between prepreg layers, thereby enhancing production efficiency. However, if the temperature rises excessively and rapidly, it […]

炭素繊維とアルミハニカムパネルの遮音効果とは?

炭素繊維アルミニウムハニカムサンドイッチ複合構造の遮音特性 炭素繊維アルミニウムハニカムサンドイッチ複合構造は、その遮音特性が車内騒音レベルに大きく影響する航空機や高速鉄道での利用が増加している。研究の結果、1000Hz以下の周波数範囲では、「炭素繊維複合パネル+アルミハニカムコア+炭素繊維複合パネル」構造の遮音性は、同サイズの「アルミ合金パネル+アルミハニカムコア+アルミ合金パネル」構造の遮音性に劣ることがわかった。同様に、100~3150Hzの範囲では、加重遮音率もアルミ合金製より低い。しかし、ハニカムコアの厚みを増すと、遮音性が向上することがデータから示唆されている。

連続炭素繊維強化熱可塑性樹脂プリプレグ製造の進歩

1.含浸技術の新機軸 従来の方法では、高粘度の熱可塑性樹脂を扱う場合、樹脂の流動性と繊維の濡れ性の点で不十分なことが多い。これに対処するため、研究者は懸濁ホットメルト法と超音波アシスト含浸法を導入した。懸濁ホットメルト法は、水性懸濁液中に樹脂粉末を分散させ、超音波キャビテーションを利用して繊維トウを膨張させ、樹脂顆粒を繊維間に均一に埋め込む。その後の高温溶融と圧密化により、PEEKやPPSのような高性能樹脂の大量生産が可能になる。この環境に優しいプロセスは、連続生産を可能にし、プリプレグの均一性と機械的特性を高めます。超音波アシスト含浸は、高周波振動を利用して樹脂の表面張力を低下させ、樹脂の浸透を向上させ、気孔率を減少させながら、プリプレグの均一性と機械的特性を向上させます。

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

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,
