硼纤维本身就是一种复合材料。其典型的制造方法是把一根直径12.5μm的钨丝通过玻璃反应室,钨丝电阻加热后引起反应室内三氯化硼与氢气反应,而使元素硼沉积在钨丝上,形成一层包套,这就是所谓的硼纤维,它的直径已达到100～200μm。硼纤维的拉伸强度超过了高强度钢,达到34.32MPa,密度只有2.5g/cm~3,强度比普通金属(钢、铝等)高4～8倍。目前硼 Boron fiber itself is a composite material. The typical manufacturing method is to a diameter of 12.5μm tungsten wire through the glass reaction chamber, tungsten wire resistance heating reaction caused by boron trichloride and hydrogen reaction, leaving the elemental boron deposited on the tungsten wire, forming a layer of package This is the so-called boron fiber, its diameter has reached 100 ~ 200μm. Tensile strength of boron fiber exceeds that of high strength steel, reaching 34.32MPa, density of only 2.5g / cm ~ 3, the strength of ordinary metal (steel, aluminum, etc.) 4 to 8 times higher. Currently boron
