代寫:CFRP材料拓撲優化

就優點而言,儘管這種材料被認爲是在已經使用鋼材和其他材料的應用中使用,但可以說,在某些情況下,CFRP的成本也可能高得令人望而卻步。並不是所有的應用都希望使用CFRP複合材料。在某些情況下,有必要使用更堅固的複合材料,因此具有更大的密度,即使強度是一種權衡。由於這些問題,優化本身成爲一種權衡,因此CFRP不能應用於此。其次,碳纖維增強塑料的可用性是由市場決定的,市場條件、可用性、需求和更多將取決於供應,或者對產品的更高需求可能導致爲該產品備貨的供應商更少。不同行業對碳纖維的要求也不盡相同。一些工業使用的碳纖維更商業化,因此,在航空航天應用方面,或在其他方面,如研究工作、實驗等方面,這裏的等級預期確實較低至中等。可以說,碳纖維的使用將會有很大的變化。單是成本問題並不是這裏的主要問題,質量問題也起了作用。最後,儘管優化帶來了好處,但對某些行業的成本擔憂將使其過於昂貴。原碳纖維是按價格出售的,購買碳纖維增強塑料的價格可能是原碳纖維的5倍或25倍左右。這也比玻璃纖維貴。在使用鋼的地方,由於額外的成本,CFRP和鋼的混合使用可能會再次變得昂貴。

電導率作爲一種特性被認爲取決於所討論的應用。碳纖維增強塑料與大多數碳纖維複合材料一樣,通常具有極強的導電性。現在的應用需要極高的導電性,因此對CFRP來說是有意義的。如果一個項目已經使用了一些碳纖維,那麼CFRP可以很容易地替代它。這種形式的替代將不會有問題,因爲兩者都是碳纖維,因此被認爲是重疊在大多數共同的特點。然而,這可能不是玻璃纖維的情況。在某些應用中,可能需要較低的電導率。由於導電率較低,因此需要使用玻璃纖維GFRP,這將在接下來討論。另一方面,玻璃鋼是一種不能輕易被碳纖維取代的材料。事實上,在使用玻璃纖維的地方,如果同時使用GFRP,由於觀察到損耗的可能性,優化可能是不可能的。在許多公用事業類型的行業中,可以觀察到該行業可能嚴重依賴於使用玻璃纖維而不是碳纖維。在公用事業行業,玻璃纖維將優先在實施電力線,例如或梯子的軌道。公用事業公司的人在很多地方使用梯子,這些地方接觸電的機會通常很高,這就導致人們觸電的情況。因此,在這裏使用玻璃線代替,即使梯子接觸到某種形式的電力線,觸電的機率也會降低。與GFRP或其他碳纖維不同,玻璃纖維根本不導電。儘管有這些缺點,碳纖維複合材料的使用和它在製造業中所具有的優勢形式是不能抹黑的。成本仍然是一個大問題,但是隨着這種產品的技術進步,成本可以降低。製造方面的進步也得到了實現,這將導致更好或更高的產量,這將使材料更商業化,可用於一系列應用。特別是消費部門、工業部門、汽車部門以及更多的部門將能夠充分利用其長期利益。

In terms of advantages, although the material as such is considered to be in use in applications that are already making use of steel and others, it could be said CFRP could be cost prohibitive in some cases, too. Not all applications would want to make use of a CFRP composite. In some cases, it would be necessary to make use of composites that are sturdier and hence has a more density, even if strength is a trade-off. Where optimization itself becomes a trade off because of these concerns, CFRP cannot be applied there. Secondly, CFRP in its availability would be market determined meaning, the market conditions, the availability, the demand and more would be based on the supply, or alternatively higher demand for the product could result in less suppliers stocked for the product. The form of carbon fiber required also varies across industries. Some industries make use of carbon fibers which are more commercial and hence the grade expected here is really lower to middle on the other hand in the case of aerospace applications or as seen in the context of others such as research work, experimentations, etc. It could be said that the carbon fiber use would vary dramatically. The cost concerns alone are no the major concerns here and the quality concerns also come out to play. Finally, despite the optimization benefit, the costs concern for some industries would make it too expensive. Raw carbon fiber is sold at a price and the purchase of CFRP could be anywhere from around 5 times or 25 times the price. This is more expensive than fiberglass as well. Where steel is used, the mix of CFRP and steel for use could again be expensive because of the additional costs.

Conductivity as a characteristic is seen to depend on the application in question. CFRP as with most carbon style of fiber composites is usually extremely conductive. Now where the application requires extreme conductivity, hence it makes sense to CFRP. Where a project is making use of some carbon fiber already, then CFRP can easily be substituted for it. This form of substituting would not be problem as both are carbon fibers and hence are seen to be overlapping in most of the common characteristics. However, this might not be the case for fiber that is glass. In some applications, low level of conductivity might be required. The low level of conductivity would have necessitated the use of glass fibers GFRP which will be discussed next. The GFRP on the other hand is one that cannot be easily substituted with the CFRP. In fact, where the glass fibers are used, if the GFRP is also used, the optimization might not be possible because of the chances of wastage observed. In many of the utility style industries, it is observed that the industry might be heavily reliant on the use of the glass fiber over the carbon fiber. In the utility industry, the glass fibers would be preferred when implementing power lines, for instance or for the rails of the ladder. Utility people use their ladders in many areas where the chances of contact with electricity is usually high and this leads to situations where the person gets electrocuted. Therefore, here where glass lines are used instead, even if the ladder were to come into contact with some form of powerline, the chances of electrocution would be lower. The glass fiber unlike GFRP or other carbon fibers does not conduct at all. Despite these disadvantages, the use of CFRP and the form of advantages it holds in general for the manufacturing industry cannot be disreputed. The cost still remains a big concern, but with the form of technological advancements that are happening for this product, the costs could be driven down. Manufacturing advancements are also implemented as well that would lead to better or higher production and this could make the material more commercially available for an array of applications. In particular the consumer sector, the industrial, the automotive sector and more would be able to fully avail of its benefits in the long run.
