原文：Development of fly ash-based automotive brake lining
Abstract
Coal-fired power plants all over the world generate huge amounts of fly ash each year, 70 million tons of which are produced in theUnited States alone. Only 40% of all fly ashes generated in the USA find beneficial applications and rest have to be disposed off, which is burden for the generation industry. Fly ash particles possess certain characteristics that make them suitable for use in friction composites
as a filler material. An attempt has been made through this research to incorporate more than 50wt% of fly ash particles in automotive brake lining friction composites. This paper presents the research carried out on development of friction composites, using fly ash obtained from a specific power plant in Illinois. Ingredients such as phenolic resin, aramid pulp, glass fiber, potassium titanate, graphite, aluminum fiber and copper powder were used in the composite development phase, in addition to the fly ash. The developed brake liningcomposites have exhibited consistent coefficients of friction in the range of 0.35–0.4, and wear rates lower than 12wt%.

摘要
火力發(fā)電廠每一年在全世界產(chǎn)生大量的粉煤灰, 其中美國就能獨(dú)自產(chǎn)生7千萬噸。在美國只有40%的粉煤灰能夠被有效利用而剩下的則必須進(jìn)行處理，這些就成為了工業(yè)負(fù)擔(dān)。粉煤灰顆粒具有某些特性,這使他們作為填料而適用于摩擦復(fù)合材料。人們通過研究試圖將超過50wt%的粉煤灰顆粒作為汽車剎車片摩擦復(fù)合材料。這篇論文介紹了這項(xiàng)研究關(guān)于摩擦復(fù)合材料的發(fā)展并采用了伊利諾伊州的某一家發(fā)電廠的粉煤灰。采用酚醛樹脂、玻璃纖維、芳綸漿料、石墨、鈦酸鉀、鋁纖維和銅粉以及粉煤灰等用于復(fù)合材料的研發(fā)。所研制的汽車剎車片復(fù)合材料的摩擦系數(shù)在穩(wěn)定的范圍（0.35-0.4），磨損率低于12wt%。
