Description

一种碳纤维保温板材预制体
技术领域
本发明涉及复合纤维技术领域，特别是涉及一种碳纤维保温板材预制体。
背景技术
碳纤维保温板材预制体，通常是由碳纤维层与碳纤维网胎交替叠层针刺而成的复合纤维预制体，因其具有耐高温、耐摩擦和质地轻的特性，广泛应用于航空航天、能源、交通和轨道领域；现有的碳纤维板材预制体，通常包括两层碳纤维层和一层碳纤维网胎，碳纤维网胎位于碳纤维层之间，这样的复合纤维针刺预制体，由于碳纤维的特性，存在抗冲击强度较低，保温效果不佳的技术问题。
发明内容
本发明的目的在于公开一种结构强度较高，韧性较高且具有良好保温效果的碳纤维保温板材预制体。
为实现上述发明目的，本发明公开了一种碳纤维保温板材预制体，包括外层碳纤维层、内层碳纤维层、设置在所述外层碳纤维层与内层碳纤维层之间的碳纤维网胎，所述外层碳纤维层与内层碳纤维层内含碳纤维长丝，所述碳纤维网胎内含碳纤维短丝，以及设置在碳纤维网胎两侧的弹性缓冲层。
作为本发明的进一步改进，所述碳纤维长丝和碳纤维短丝的外侧面依次设置有热解碳涂层、碳化硅涂层和碳化钽涂层，所述碳纤维网胎的碳纤维短丝之间还设置有酚醛树脂基体层。
作为本发明的进一步改进，所述热解碳涂层的厚度大于0.5μm并小于0.8μm，所述碳化硅涂层的厚度大于1μm并小于1.5μm，所述碳化钽涂层的厚度大于1.5μm并小于2μm。
作为本发明的进一步改进，所述弹性缓冲层为特氟龙纤维。
有益效果：通过在碳纤维网胎设置碳纤维短丝，以及设置在碳纤维网胎两侧的弹性缓冲层，有效地提高了碳纤维保温板材预制体的韧性，同时也具有良好保温效果。
附图说明
图1为本发明一种碳纤维保板材预制体的结构示意图。
图2为本发明中碳纤维短丝剖向的结构示意图。
具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
如图1和图2所示，一种碳纤维保温板材预制体100，包括外层碳纤维层10、内层碳纤维层20、设置在所述外层碳纤维层10与内层碳纤维层20之间的碳纤维网胎30。外层碳纤维层10与内层碳纤维层20内含碳纤维长丝，碳纤维网胎30内含碳纤维短丝2，以及设置在碳纤维网胎30两侧的弹性缓冲层40。外层碳纤维层10与内层碳纤维层20的厚度相等。
具体的，在本实施方式中，该弹性缓冲层40为特氟龙纤维。特氟龙纤维的直径为20～50μm，并通过经纬编制的方式形成该弹性缓冲层40，具体的该弹性缓冲层40的厚度为外层碳纤维10或者内层碳纤维层20的二分之一。
在本实施方式中，该碳纤维长丝和碳纤维短丝2的外侧面依次设置有热解碳涂层4、碳化硅涂层5和碳化钽涂层6，所述碳纤维网胎30的碳纤维短丝2之间还设置有酚醛树脂基体层3。热解碳涂层的厚度大于0.5μm并小于0.8μm，所述碳化硅涂层的厚度大于1μm并小于1.5μm，所述碳化钽涂层的厚度大于1.5μm并小于2μm。
热解碳涂层4、碳化硅涂层5和碳化钽涂层6的简称分别为PyC、SiC和TaC，这样，碳纤维表面均匀致密的PyC、SiC和TaC多层结构，可有效提高内层碳纤维层20的强度和韧性；PyC涂层可以有效防止SiC涂层制备过程中对内层碳纤维层20中碳纤维的损伤，改变碳纤维的表面状态，减少或修复纤维表面的缺陷及编制损伤，有效提高碳纤维短丝的强度；SiC和TaC陶瓷具有较高的强度，即使TaC涂层断裂，SiC涂层仍然能够有效承载，这样碳纤维原丝的抗弯强度得到有效提高；而酚醛树脂基体层可以有效提高预制体的抗拉伸性和弯曲性能，层间抗剪切性能也较好；PyC、SiC和TaC涂层可采用化学气相渗透法在碳纤维丝表面依次制备。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
