碳纤维重要性能之一,就是它的密度。公认的可用来测定碳纤维密度的密度梯度柱法,在我们实验室中经过一系列改进。密度梯度柱本身是个园筒,内盛两种不同密度的液体,由于上下层之间液体内扩散形成了密度梯度。本法的实质在于寻找碳物料密度
One of the important properties of carbon fiber is its density. The proven density gradient column method that can be used to determine the density of carbon fibers is a series of improvements in our laboratory. Density gradient column itself is a cylinder, filled with two different density of liquid, due to the liquid diffusion between the upper and lower layer to form a density gradient. The essence of this law is to look for carbon material density
