Why has fiberglass become the domin

Why has fiberglass become the dominant fiber reinforcement?
Fiberglass is dominant as a reinforcement fiber simply because it has high strength and
high stiffness at a low price. A comparison of fiberglass with carbon fibers, the stiffest
reinforcement material, and with the other principal reinforcement fibers shows just how good
fiberglass is when cost is considered. (See Table 1.) Fiberglass has over ten times the strength
value (tensile strength per unit cost) and nearly 5 times the stiffness value (modulus per unit cost)
as the other major composite reinforcement fibers. Hence, when cost is a major driving force in
the selection of a reinforcing material, fiberglass usually is preferred.
In view of these obvious cost benefits for fiberglass, you might ask “What are the reasons
that someone would ever choose any other fiber?” In the case of carbon fibers, that reason is
usually stiffness for a very high-valued application. For instance, some estimates of the cost to lift
one pound of payload into orbit range to over $100,000. Under these conditions the criteria for
selecting a reinforcement material is the specific strength (strength divided by the specific gravity)
or, more often, the specific stiffness (stiffness divided by the specific gravity). Carbon fibers have
substantially better specific strength and specific stiffness values than fiberglass. Hence, when the
weight of the fiber is a strong driving force, carbon fibers can be easily justified.

为什么玻璃纤维已成为占主导地位的纤维加固吗？玻璃纤维是主导作为纤维总只是因为它具有高的强度和价格低廉的高刚度。严厉的碳纤维与玻璃纤维的比较加固材料，与其它主要的总纤维显示多么好玻璃纤维是考虑成本时。（见表 1）。玻璃纤维有超过十倍的力量值 （拉伸强度每单位成本） 和近 5 倍的刚度值 （每单位成本模数）像其他主要复合纤维总数。因此，当成本主要的驱动力增强材料的选择，玻璃纤维通常是首选。鉴于这些明显成本效益为玻璃纤维，你可能会问"的原因是什么那有人会永远选择任何其他纤维吗？"在碳纤维，原因是通常刚度很高价值的应用程序。例如，一些人估计的成本提升一磅的载荷送入轨道范围至十万元以上.在这些条件下的标准总的选材是比强度 （强度除以比重）或者，更多时候，具体的刚度 （刚度除以比重）。碳纤维具有极大地更好的比强度、 比刚度值比玻璃纤维。因此，当纤维重量是强大的驱动力，碳纤维可以很容易有正当理由。

为什么成为安切洛蒂的显性玻纤纤维增强？玻纤强化纤维可以作为一个优势，因为它有高强度和在一个低价格的高刚度。一个比较硬的碳纤维的纤维，增强材料，增强纤维和其他委托节目只是如何好当纤维被认为是一个成本。（见表1）。纤维的强度已经过十时报值（拉伸强度每单位成本）和刚度值的近5倍（模量通过单位成本）作为其他专业的强化纤维复合材料。因此，当成本是一个主要的驱动力选择一个玻纤补强材料，通常是首选。在视图上的成本效益分析的纤维，你可以问“是什么原因那有人会选择任何其他纤维？在案例的原因是碳纤维，这是通常，一个非常高的刚度值的应用。例如，一些成本估计的解除一磅的有效载荷到轨道过程学院到100000美元。论文在标准条件下选择一个特定的强化材料的强度（强度除以特定的重力）或，更经常性（刚度，刚度除以特定的重力）。有碳纤维substantially更好的特异性和特异性值比玻纤强度刚度。因此，当的纤维量是一个强大的驱动力，可以方便合理的碳纤维。
