El punzonado con agujas de fieltro de fibra de carbono consiste en abrir, peinar y colocar fibras cortas en una red de fibras y, a continuaci\u00f3n, reforzar la red de fibras en tela mediante agujas. Las agujas tienen ganchos y espinas que perforan repetidamente la red de fibras. Los ganchos y las fibras se refuerzan para formar fieltro crudo de fibra de carbono perforado con agujas. La producci\u00f3n de fieltro de fibra de carbono por punzonado con aguja consiste en reforzar y sujetar la red de fibra esponjosa mediante la acci\u00f3n de punci\u00f3n de la m\u00e1quina de punzonado con aguja para obtener resistencia.<\/p>

La red de fibras es perforada repetidamente por una aguja con una p\u00faa en el borde de una secci\u00f3n transversal triangular (u otra secci\u00f3n transversal). Cuando la p\u00faa atraviesa la red de fibras, la superficie y las fibras interiores locales de la red de fibras se ven forzadas a penetrar en la red de fibras. Debido a la fricci\u00f3n entre las fibras, la red de fibras esponjosa original se comprime. Cuando la aguja se retira de la red de fibras, los haces de fibras insertados se desprenden de la p\u00faa y permanecen en la red de fibras. De este modo, muchos haces de fibras enredan la red de fibras de modo que ya no puede recuperar su estado esponjoso original. Despu\u00e9s de perforar muchas veces con la aguja, se perfora un gran n\u00famero de haces de fibras en la red de fibras, de modo que las fibras de la red de fibras se enredan entre s\u00ed, formando as\u00ed un fieltro de fibra de carbono en bruto con una cierta resistencia y grosor. A continuaci\u00f3n, el fieltro de fibra de carbono original se oxida previamente y se carboniza para obtener el fieltro de fibra de carbono (proceso de producci\u00f3n del fieltro de fibra de carbono a base de PAN).<\/p>

El fieltro de fibra de carbono tiene una alta resistencia axial y m\u00f3dulo, baja densidad, resistencia a temperaturas ultra altas en entornos no oxidantes, buena resistencia a la fatiga, resistencia a \u00e1cidos y \u00e1lcalis, resistencia a altas temperaturas, buena transmitancia de rayos X, buena conductividad el\u00e9ctrica y t\u00e9rmica, y buenas propiedades de blindaje electromagn\u00e9tico. Se utiliza cada vez m\u00e1s en la industria, la atenci\u00f3n m\u00e9dica, la protecci\u00f3n del medio ambiente y otros campos.<\/p>

Las preformas punzonadas de fibra de carbono est\u00e1n hechas de tela de fibra de carbono con un \u00e1ngulo de plegado optimizado, combinadas con relleno de fibra corta de carbono y conectadas como un todo mediante procesos especiales. Los materiales compuestos de C\/C se fabrican mediante deposici\u00f3n de vapor y compounding, lo que constituye una estructura portante ligera, resistente y duradera. Las especificaciones habituales incluyen piezas normales, como placas planas y ollas, as\u00ed como piezas de formas especiales, como tubos gu\u00eda y crisoles.<\/p>

La preforma punzonada de fibra de carbono es un tipo de preforma de material compuesto de C\/C. El proceso de formaci\u00f3n de la preforma punzonada con aguja consiste en utilizar malla de fibra como materia prima para el punzonado con aguja, y utilizar una aguja especial con ganchos invertidos para el punzonado con aguja a fin de formar un refuerzo de estructura de malla casi tridimensional con cierta resistencia tanto en el plano como entre las capas. La preforma punzonada con aguja supera la d\u00e9bil resistencia entre capas de la preforma laminada en 2D, y al mismo tiempo supera la debilidad de la preforma tejida en 3D, que es un proceso complejo y de alto coste.<\/p>

Las preformas de fibra de carbono se fabrican con fibra de carbono de alta resistencia, tela de fibra de carbono y fieltro de fibra de carbono mediante estratificaci\u00f3n repetida y punzonado. Est\u00e1n rellenas de fibras cortas y tienen cierta densidad y firmeza. Los productos incluyen varios crisoles de campo caliente, tubos gu\u00eda, crisoles, preformas de barril de aislamiento y preformas de placa plana. Los productos se componen con valor C\/C en componentes de campo caliente ligeros, resistentes y duraderos. Tambi\u00e9n pueden transformarse en carriles de alta velocidad, discos de freno para autom\u00f3viles, elementos de fijaci\u00f3n y productos especiales.<\/p>
