鐵和鋁顆粒模擬燃料系統(tǒng)里面的金屬污染物。這些原料在生產(chǎn)的時候要確保大小和角度以能代表真實世界中的顆粒。這些顆粒大小用篩網(wǎng)進(jìn)行了驗證,應(yīng)注意的是,由于金屬屑的形狀,*大顆粒要大于篩網(wǎng)的目數(shù)。 SAE AIR 4246 A.8 – Carbon Fibre Rods碳纖維 More recently carbon fibre has been used to in the production of aircraft, this necessitated the inclusion of the carbon fibre rods as a fuel contaminant. Particle Technology use a bespoke process to create the carbon fibre in the size ranges specified. Determining the particle size of a fibre is very difficult, Particle Technology use image analysis to measure the length and width of the fibres. 碳纖維現(xiàn)在用于飛機(jī)生產(chǎn),使得碳纖維也變成燃料系統(tǒng)的污染物。確保碳纖維的尺寸是很困難的,英國Particle Technology使用圖像技術(shù)保證纖維的長度和寬度。 SAE AIR 4246 A.9 – Graphite Epoxy Composite (GEC)石墨環(huán)氧樹脂復(fù)合材料
