Abstract
本发明涉及一种快速制备AlN改性C/C‑SiC摩擦材料的方法,首先通过模压的方式将混合均匀的短碳纤维、酚醛树脂、工业硅粉和铝粉等压制成纤维增强树脂块体,后经过碳化和陶瓷化热处理得到C/C‑AlN‑SiC摩擦材料。本发明利用活性金属铝与载气氮气或树脂碳化过程中生成的碳氢气体反应体积膨胀的特性,填补材料中因树脂碳化和硅碳反应收缩产生的孔隙,提升材料致密度,缩减致密化工艺周期,降低制备成本。
Description
技术领域
本发明属于制动摩擦材料领域,涉及一种碳纤维增强陶瓷基复合材料的制备方法,特别涉及一种低成本快速制备AlN改性短碳纤维增强C/C-SiC摩擦材料的制备方法。
背景技术
C/C-SiC摩擦材料是继粉末冶金摩擦材料和C/C摩擦材料之后的新一代摩擦材料,具有低密度、高比强、耐高温、高耐磨、摩擦性能稳定、环境适应性好等诸多优点。
目前,制备C/C-SiC摩擦材料主要途径为:使用连续碳纤维毡作为预制体,先采用化学气相渗透工艺在预制体表面沉积一层热解碳,后通过聚合物浸渍裂解或反应熔体浸渗工艺引入SiC基体并致密化。但是该法工序繁多,生产周期长,成本高,在一定程度上限制了C/C-SiC摩擦材料在民用领域的应用。
文献1“专利公开号为CN103553695A的中国专利”报道了一种采用短碳纤维作为增强体的碳陶复合材料制动盘制备方法。该方法先将短切碳纤维、硅粉、粘结剂、无水乙醇混合均匀后按设计的制动盘胚体压制成块,后将压制得到的碳纤维增强胚体碳化得到C/C多孔体,然后采用聚碳硅烷与二乙烯基苯的混合溶液浸渍C/C多孔体,固化之后生成SiC基体,重复浸渍固化至一定密度后对所得到的C/C-SiC复合胚体进行2-5min的熔融硅浸渍,得到表面摩擦层为Si的C/C-SiC摩擦材料。文献2“专利公开号为CN101486588A的中国专利”报道了一种短碳纤维增强C/C-SiC摩擦材料的制备方法。该方法先将短切碳纤维、石墨粉、工业硅粉、粘结剂冷压成块体,后对制成的C/C-Si块体进行机械破碎和造粒,再将颗粒温压成C/C-Si素胚,对素胚碳化后制成C/C-Si多孔体,最终对多孔体进行熔融硅浸渗制成C/C-SiC摩擦材料。
上述两种采用短碳纤维作为增强相,通过模压的方式将短纤维、树脂、填料压制成纤维增强树脂块体,经碳化与致密化处理后制成C/C-SiC摩擦材料的工艺路线,不失为一种低成本快速制备C/C-SiC摩擦材料的手段。但其中采用的重复浸渍固化和熔融硅浸渗工艺不仅需要诸如压力热处理炉等设备,还增加了数百或数十小时的制备周期。因此,开发一种无需后续致密化处理的C/C-SiC摩擦材料制备工艺,对于缩短制备周期,降低生产成本,拓展摩擦材料的应用具有重要意义。
发明内容
要解决的技术问题
为了避免现有技术的不足之处,本发明提出一种低成本快速制备AlN改性C/C-SiC摩擦材料的制备方法,针对现有C/C-SiC摩擦材料制备工艺中致密化处理周期长的不足之处,通过在模压过程中引入活性填料Al来增加热处理之后材料的致密度,从而缩减致密化周期,提升生产效率。

步骤2:将模压后得到的纤维增强树脂块体进行碳化热处理和陶瓷化热处理,载气气氛为N2,载气流量为20-80ml/min,升温至900-1100℃保温2-6h,再升温至1400-2100℃保温2-6h,降温至300℃后随炉冷却至室温,得到C/C-AlN-SiC复合材料;
所述热处理时的升温和降温速率为1-5℃/min。
所述步骤2的碳化热处理和陶瓷化热处理分为两步:先进行碳化热处理,随炉冷却至室温后,再进行陶瓷化热处理,得到C/C-AlN-SiC复合材料。
所述碳化热处理的热处理温度为900-1100℃,载气气氛为N2的载气流量为20-80ml/min,保温时间为2-6h,降温至300℃后随炉冷却至室温;所述热处理时的升温和降温速率为1-5℃/min。
所述陶瓷化热处理热处理温度为1600-2100℃,载气气氛为N2,载气流量为20-80ml/min,保温时间为2-6h,降温至300℃后随炉冷却至室温;所述热处理时的升温和降温速率为1-5℃/min。

有益效果
本发明提出的一种低成本快速制备AlN改性C/C-SiC摩擦材料的制备方法,首先通过模压的方式将混合均匀的短碳纤维、酚醛树脂、工业硅粉和铝粉等压制成纤维增强树脂块体,后经过碳化和陶瓷化热处理得到C/C-AlN-SiC摩擦材料。本发明利用活性金属铝与载气氮气或树脂碳化过程中生成的碳氢气体反应体积膨胀的特性,填补材料中因树脂碳化和硅碳反应收缩产生的孔隙,提升材料致密度,缩减致密化工艺周期,降低制备成本。
具体是:本发明首先通过模压的方式将混合均匀的短碳纤维、酚醛树脂、工业硅粉和铝粉压制成纤维增强树脂块体,后经过900-1100℃碳化热处理将材料中的树脂与Al转化为树脂碳和AlN基体,再经过1600-2100℃陶瓷化热处理使材料中的Si与碳反应生成SiC基体,得到C/C-AlN-SiC摩擦材料。Al作为活性金属,可以与载气氮气或树脂碳化过程中生成的碳氢气体反应,该类反应会带来体积膨胀,有助于填补材料中因树脂碳化和硅碳反应收缩产生的孔隙,提升材料致密度,缩减致密化工艺周期。同时,铝与氮气反应的温度为1000℃左右,高于铝的熔点,即AlN的形核长大是在熔体中发生的,以该种方式发生的体积膨胀对周围基体的损伤作用较固态相变小,并不会在材料内部产生较大的内应力。
本发明的主要优点如下:
1:树脂基复合材料转化为树脂碳基复合材料的碳化热处理常采用较低的升降温速率(约1℃/min),以防止因树脂裂解碳化过程过于剧烈而在材料中产生孔隙与裂纹等缺陷。本发明通过减少树脂含量,添加一定石墨粉作为碳源,在使材料中Si完全转化为SiC时仍有部分石墨存在以调整材料摩擦系数的前提下,增加碳化热处理的升降温速率,以缩减制备周期。本发明将碳化热处理的升降温速率由1℃/min提高到5℃/min,材料表面并未出现变形和裂纹,模压方向膨胀1.88%,垂直于模压方向收缩0.009%。
2:采用将短碳纤维、酚醛树脂、工业硅粉和铝粉压制成块体后热处理制备C/C-SiC复合材料的方法,利用Al在反应过程中体积膨胀的特点,直接在热处理的同时对材料进行致密化,省去致密化热处理工艺,缩短了制备周期。相较于再经过两次真空浸渍、交联固化、裂解碳化的制备方法,本发明制备周期由约118h缩短为约18h,为碳陶摩擦材料产业化,推进碳陶制动盘深入民用市场提供了有益思路。
3:通过引入活性金属Al,利用其与载气氮气或树脂碳化过程中生成的碳氢气体反应体积膨胀的现象,填补材料因热处理过程中树脂收缩和硅碳反应生成的孔隙。本发明相较于填料中未添加Al的C/C-SiC复合材料孔隙率下降了33.2%;相较于经过两次真空浸渍、交联固化、裂解碳化工艺后的C/C-SiC复合材料孔隙率下降了24.9%。该结果同时表明,真空浸渍、交联固化、裂解碳化工艺致密化效率低,而压力浸渍-固化-碳化工艺不仅对热处理设备提出了更高的要求,还增加了使用过程中水、电等能源的消耗。本发明提出的致密化工艺既能实现优异的致密化效果,也在一定程度上减轻了对高温高压设备的依赖。
4:AlN改性的C/C-SiC复合材料的磨损率为1.277×10-15m3N-1m-1,相较于改性前样品34.765×10-15m3N-1m-1的磨损率下降了一个数量级,说明该方法制备的碳陶摩擦材料同样具有优异的摩擦磨损性能。
附图说明
附图中的对比例1为未经致密化工艺处理的原始样品;对比例2为在对比例1基础上经过两次真空浸渍、交联固化、裂解碳化工艺的样品;实施例1为在对比例1的基础上减少了10%体积分数鳞片石墨粉,添加了10%体积分数Al粉的样品;实施例2为在对比例1基础上减少了20%体积分数鳞片石墨粉,添加了13%体积分数Al粉,7%体积分数Al2O3粉的样品。
图1为四种C/C-SiC摩擦材料制备周期对比图,图中可以看出,采用本文所述工艺可以很大程度上降低材料的致密化周期,制备周期由对比例2的118h缩减为实施例2的18h;
图2为四种C/C-SiC摩擦材料孔隙率对比图,图中可以看出,本文所述工艺在缩减生产周期的同时,材料的致密化度也得到了一定程度的提升,材料的孔隙率由对比例1的24.85%下降为实施例2的16.6%;
图3为四种C/C-SiC摩擦材料动摩擦系数与磨损率对比图,图中可以看出,采用本文所述工艺制备出的材料具有优良的摩擦磨损性能,实施例2的平均动摩擦系数为0.287,磨损率由对比例1的34.765×10-15m3N-1m-1下降为实施例2的1.277×10-15m3N-1m-1。
图4为实施例2在摩擦磨损测试后磨痕区域的微观形貌图,图中可以看出,磨痕区域由少部分磨屑区与大部分摩擦膜区组成。摩擦膜产生于摩擦过程作用于材料表面的交变应力,该区域相较于原复合材料具有更高的强度与致密度。摩擦膜的形成在稳定动摩擦系数的同时,还能降低复合材料的磨损率。
