【碳纖維棒材料】碳纖維,碳纖維棒，石墨都是由碳組成的容易混淆
碳纖維，碳纖維棒，石墨都是由碳組成的容易混淆,下面提供了一些方法區(qū)分：
石墨的分子結(jié)構(gòu)為六邊形，碳原子間的鍵合很強(qiáng)，但平面層相距較遠(yuǎn)，具有柔軟、熔點(diǎn)高、化學(xué)性質(zhì)穩(wěn)定等特點(diǎn)。它的表面是黑色和灰色的，看起來好像它有一層油，它的硬度只有1%。石墨可分為三種類型：致密結(jié)晶石墨、隱晶質(zhì)石墨和片狀石墨。它們的性質(zhì)和形狀略有不同，應(yīng)用領(lǐng)域也不同。
It also has the advantages of high thermal conductivity, good electrical conductivity, X-ray penetration, fatigue resistance, friction resistance, and good chemical stability. Whether in the military or civilian fields, it involves the manufacture of high-tech items such as automobiles and airplanes, as well as the production of small objects such as cups, glasses, and mirror frames. They are indispensable new materials in the 21st century.
First, carbon fiber is light in weight and high in strength. Its specific strength and specific modulus are much higher than other materials.
Carbon rod is one of the most widely used non-metallic materials, with good electrical conductivity, chemical stability and high temperature resistance. Its thermal expansion coefficient is small, it is not easy to be deformed, and its hardness is high, but its texture is brittle and its alkali resistance is worse than acid resistance. Carbon rods are used in machinery manufacturing, metallurgy, chemical industry, national defense and security and other fields, and can be used as battery negative electrodes, spectrum analysis electrodes, and arc lamps.
碳纖維棒是目前應(yīng)用最廣泛的非金屬材料之一，具有良好的導(dǎo)電性、化學(xué)穩(wěn)定性和耐高溫性能。其熱膨脹系數(shù)小，不易變形，硬度高，但質(zhì)地脆，耐堿性差于耐酸性。碳棒用于機(jī)械制造、冶金、化工、國防安全等領(lǐng)域，可用作電池負(fù)極、光譜分析電極、弧光燈。
都知道碳纖維，碳棒，石墨都是由碳組成的，有時(shí)候容易混淆。事實(shí)上，它們是完全不同的材料，碳纖維是通過在幾千攝氏度的高溫下對無機(jī)纖維進(jìn)行預(yù)氧化和碳化而成的，碳棒是由碳、石墨和粘結(jié)劑擠壓成型而成的，石墨是一種軟礦物材料。石墨的分子結(jié)構(gòu)為六邊形，碳原子間的鍵合很強(qiáng)，但平面層相距較遠(yuǎn)，具有柔軟、熔點(diǎn)高、化學(xué)性質(zhì)穩(wěn)定等特點(diǎn)。它的表面是黑色和灰色的，看起來好像它有一層油，它的硬度只有1%。石墨可分為三種類型：致密結(jié)晶石墨、隱晶質(zhì)石墨和片狀石墨。它們的性質(zhì)和形狀略有不同，應(yīng)用領(lǐng)域也不同。
它還具有導(dǎo)熱功率高、導(dǎo)電性好、X射線穿透、抗疲勞、抗摩擦、化學(xué)穩(wěn)定性好等優(yōu)點(diǎn)。無論是軍事領(lǐng)域還是民用領(lǐng)域，都涉及到汽車，飛機(jī)等高科技物品的制造，以及杯子，眼鏡，鏡框等小物件的生產(chǎn)原料，是21世紀(jì)不可缺少的碳纖維定制加工新材料.
首先，碳纖維重量輕，強(qiáng)度高。它的比強(qiáng)度和比模量遠(yuǎn)高于其他材料。
