聚醚醚酮是指大分子主链由芳基、酮键和醚键组成的线性聚合物，其分子式为
Figure PCTCN2018082397-appb-000001
从上述分子式可以看出，聚醚醚酮是一种线性芳香族高分子化合物，其属于半结晶热塑性塑料，其熔点为334℃，具有机械强度高、耐高温、耐冲击、阻燃、耐酸碱、耐水解、耐磨、耐疲劳、耐辐照及良好的电性能。另外，聚醚醚酮还具有优越的尺寸稳定性，温度和湿度对聚醚醚酮的影响很小。
碳纤维是一种含碳量在95％以上的高强度、高模量纤维的新型纤维材料，它是由片状石墨微晶等有机纤维沿纤维轴向方向堆砌而成，经碳化及石墨化处理而得到的微晶石墨材料。碳纤维“外柔内刚”，质量比金属铝轻，但强度却高于钢铁，并且具有耐腐蚀性、高模量的特性，同时又兼备纺织纤维的柔软可加工性，是新一代增强纤维。碳纤维具有许多优良性能，其轴向强度和模量高，密度低、比性能高，无蠕变，非氧化环境下耐超高温，耐疲劳性好，热膨胀系数小，且具有各向异性，耐腐蚀性好，导电、导热和电磁屏蔽性能优良。

聚醚醚酮不仅具有高耐热性、高强度、高模量和高韧性等优异的综合性能，而且具有出色的耐水解性和尺寸稳定性，但是其存在热变形温度偏低、摩擦系数高的缺陷，导致其在摩擦过程中生热很快，导热困难，聚热严重，因此聚醚醚酮需要与其它改性料共混以制备性能优良的偏航刹车片。
本发明以聚醚醚酮为基体材料，以碳纤维和玻璃纤维为增强材料，以石墨为导热材料制得的偏航刹车片，不仅大幅提高了力学性能和耐高温性能，而且大幅降低了偏航刹车的硬度，减少了对偶的磨损，降低了噪音，同时还改善其摩擦稳定性和工况适应性，能够有效满足风力发电机偏航低速制动的要求。
在本发明的优选实施方式中，偏航刹车片主要由按质量份数计的如下原料制备：聚醚醚酮70-75份，碳纤维10-15份，玻璃纤维3-5份，石墨3-5份，硫化铜1-3份，碳纳米管1-3份。

本发明中通过聚醚醚酮、石墨、碳纤维、玻璃纤维、硫化铜和碳纳米管的相互协同，有效降低了偏航刹车片的磨损率，减少了对偶盘的伤害，同时还提高了拉伸强度、抗压强度和剪切强度。

氮化碳是一种硬度可以和金刚石媲美而在自然界中尚未被发现的新型共价化合物，其热重分析表明在600℃空气气氛中氮化碳仍可稳定存在，证明它是一种耐高温，不易分解的材料，同时在传统的溶剂中(包括水、乙醇、富马酸二甲酯、四氢呋喃、乙醚和甲苯等)，氮化碳没有表现出可溶性和反应活性，证明它在有机溶剂中的稳定性。
通过在偏航刹车片中添加氮化碳，使得偏航刹车片的耐磨性能提高，在进行制动的过程中，材料应答性好，摩擦过程平稳，制动无尖叫。
碳化锆为黑色固体，是一种硬度大的高熔点材料和极好的高温耐火材料，具有良好的耐高温、耐腐蚀和耐磨性能，是良好的高温结构，同时还具有优良的导热性。

上述实施例1-12所提供的偏航刹车片的制备方法如下：
(a)将聚醚醚酮、碳纤维、玻璃纤维、石墨、任选的硫化铜、任选的碳纳米管、任选的硫化钼、任选的氮化碳和任选的碳化锆混合均匀；
(s)将混合物通过挤出机进行挤出造粒，制得混合物粒料；
(b)混合物粒料经过双螺杆挤出机熔融塑化后挤出，然后再将熔融的挤出料经注射机注塑成型；其中，双螺杆挤出机一区加热温度为370-375℃，二区温度为380-385℃，四区温度400-405℃，螺杆转速为100-300rpm，注射机的注射模具温度为100-200℃，注射筒温度350-450℃，注射背压1-5MPa，注射压力100-200MPa。
对比例1
本对比例提供了一种偏航刹车片，由以下原料制备而成：聚醚醚酮50份，纳米级碳纤维20份，纳米级玻璃纤维10份，纳米级石墨10份。
对比例2
本对比例提供了一种偏航刹车片，由以下原料制备而成：聚醚醚酮90份，纳米级碳纤维6份，纳米级玻璃纤维2份，纳米级石墨2份。
对比例3
本对比例与实施例2的不同之处在于，未添加纳米级碳纤维。
对比例4
本对比例与实施例2的不同之处在于，未添加纳米级玻璃纤维。
对比例5
本对比例与实施例2的不同之处在于，未添加纳米级石墨。
上述对比例1-5提供的偏航刹车片的制备方法同实施例2，在此不再赘述。
将实施例1-12所提供的偏航刹车片和对比例1-5提供的偏航刹车片分别进行力学、噪音、耐热性能和磨损率的测试，测试数据如表1所示：
表1 偏航刹车片性能测试数据表
Figure PCTCN2018082397-appb-000002
Figure PCTCN2018082397-appb-000003
通过实施例1-12与对比例1-5的对比可知，本发明实施例1-12提供的偏航刹车片以聚醚醚酮为基体树脂，以碳纤维和玻璃纤维为增强材料，以石墨为导热材料制得的偏航刹车片，不仅大幅提高了力学性能(拉伸强度、剪切强度和抗压强度)和耐高温性能(承受最高温度和承受最高持续温度)，而且大幅降低了偏航刹车的硬度，减少了对偶的磨损，降低了噪音，同时还改善了其摩擦稳定性和工况适应性，能够有效满足风力发电机偏航低速制动的要求。
通过实施例5-7与实施例8-12的对比可以看出，以聚醚醚酮、纳米级石墨、纳米级碳纤维、纳米级玻璃纤维、碳纳米管、硫化铜、硫化钼、氮化碳和碳化锆相互协同配合制备的偏航刹车片其摩擦系数进一步增大，耐高温性能进一步提升，力学性能进一步增强，综合性能得到进一步提高。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
