  1. When the content of vermiculite minerals was about 10 %, the impact strength ( nick ) and the flexural strength had maximum value, but those of the polybenzoxazine ( bisphenol a type ) / phlogopite composites had been going down. as the content of vermiculite minerals was over 5 %. hdt of the polybenzoxazine ( bisphenol a type ) / vermiculite hybrid nanocomposites was higher than that of the polybenzoxazine ( bisphenol a type )

    4幾插層狀分散的10蛙石含量的納米復合材料的物理交聯作用表現較為明顯，力學性能處于峰值； hdt高於純樹脂，並隨含量的增加而提高，含金雲母的復合材料的hdt則不隨其含量變化而變化。
  2. The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film

    試驗結果表明：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；聚四氟乙烯樹脂熱分解溫度超過400 ，但在ptfe中加入無機填料會使復合材料吸水率提高，熔融溫度及分解溫度降低，且伴有氧化分解反應；碳纖維表面含有c = o及c - o - c等極性基團，有利於提高其與其它組分的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副，在金屬表面均可形成潤滑轉移膜，從而減少金屬摩擦副表面間的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。
  3. As the content of vermiculite minerals increased, the content of the " intercalated " shape, in which crystal gallery breadth was about of 40nm, also increased. in the curing reaction processing of polybenzoxazine / vermiculite hybrid nanocomposites intercalated with bisphenol a type precursor. according to the content of vermiculite minerals, while different shape of crystal was forming, these crystals were retarding the heat ring - opening polymerization of bisphenol a type precursors in the nanocomposites

    通過對雙酚a型ben蛭石納米插層物固化過程的分析：不同蛭石含量的插層物，在形成不同納米分散狀態固化結構的過程中，蛭石晶片對雙酚a型ben的熱開環聚合有明顯不同的阻礙作用，蛭石含量為3的插層物160的凝膠化時間較純樹脂的延長約7min ，活化能高約8kj mol ，固化反應熱晗低約14j g ，使得固化物的固化程度較純樹脂低約10 ，阻礙作用最大，其它含量的次之。
  4. The ir - spectrometry analysis results show that chemical combination exists between al - zr coupling agent and fiber - like palygorskite in the modified fiber - like palygorskite and the chemical combination between al - zr coupling agent and phenolic resin is the strongest relative to the other three coupling agents, so al - zr coupling agent can be selected to improve the bonding behavior between fiber - like palygorskite and phenolic resin in the friction material

    紅外光譜分析研究表明：偶聯劑改性坡縷石中，鋁鋯偶聯劑與坡縷石在改性過程中發生了相對強烈的化學鍵合；相對于其它三種偶聯劑，鋁鋯偶聯劑和丁腈改性酚醛樹脂產生的化學鍵合最為強烈，因此可以認為鋁鋯偶聯劑能夠較好地改善摩擦材料中丁腈改性酚醛樹脂和坡縷石纖維界面結合狀況。
