【碳纖維方管】 碳纖維方管價格貴的主要原因是什么？
碳纖維方管具有質(zhì)輕高強、耐高溫、耐腐蝕抗老化等一系列有點，所以很多人都傾向于使用碳纖維制品，還有一些高科技領(lǐng)域產(chǎn)品，但是碳纖維方管制品的價格普遍偏高，這其中有什么原因在哪里？
Carbon fiber square tube has a series of advantages such as light weight, high strength, high temperature resistance, corrosion resistance and aging resistance, so many people tend to use carbon fiber products, and there are some high-tech products, but the price of carbon fiber square tube products is generally high. What is the reason for this?
碳纖維方管價格偏高主要原因就是其原料——碳纖維。所有的碳纖維制品都是由碳纖維原絲加工而成的，碳纖維原絲是將不同基體碳纖維在高溫環(huán)境中預(yù)氧化、碳化、石墨化而得到的，需要經(jīng)過多次牽伸和干燥致密化，所消耗的能源非常多，制作成本也在增加。再就是對碳纖維制品的生產(chǎn)所要求的技術(shù)非常高，碳纖維的生產(chǎn)是一個極為復雜的過程，這其中包含了一系列的物理化學反應(yīng)，并且現(xiàn)在對于更高強度和更高模量的追求，對于此研發(fā)就需要投入大量的資金，像一些對性能要求高的產(chǎn)品，就需要采用高質(zhì)量的碳纖維，那么價格就相對較高一些 。最后一個是技術(shù)的壟斷，我么都知道碳纖維的核心技術(shù)在日本、美國等少數(shù)發(fā)達國家手中，而國內(nèi)生產(chǎn)的碳纖維一般強度達不到要求，所以基本上所用的碳纖維依賴進口，南無價格就由供應(yīng)商來定，并且他們還禁止技術(shù)的外泄，所以國內(nèi)的碳纖維產(chǎn)業(yè)發(fā)展較為緩慢。
The main reason for the high price of carbon fiber products is its raw material-carbon fiber. All carbon fiber products are processed from carbon fiber precursors. The carbon fiber precursors are obtained by pre-oxidizing, carbonizing, and graphitizing different matrix carbon fibers in a high temperature environment. It needs to be drawn and dried for many times to densify. The energy is very much, and the production cost is also increasing. Furthermore, the technology required for the production of carbon fiber products is very high. The production of carbon fiber is an extremely complex process, which involves a series of physical and chemical reactions, and the pursuit of higher strength and higher modulus is now This research and development needs to invest a lot of money, like some products with high performance requirements, it needs to use high-quality carbon fiber, so the price is relatively higher. The last one is the monopoly of technology. We all know that the core technology of carbon fiber is in the hands of a few developed countries such as Japan and the United States. However, the strength of domestically produced carbon fiber generally does not meet the requirements, so basically the carbon fiber used depends on imports. It is up to the supplier, and they also prohibit the leakage of technology, so the domestic carbon fiber industry is developing slowly.
