Description

一种高强航空复合金属板
技术领域
本发明涉及一种航空复合金属板，具体地说，是一种高强航空复合金属板。
背景技术
金属板具有高强度、高刚度，加工性好的特点，在航空制造业应用最广泛的材料。但是目前，航空用金属板存在金属板重量与金属板强度之间的矛盾，若想获得强度高的胶合板，往往会导致航空金属板重量增加。在满足容积与重量要求情况下，如何提高航空用金属板的强度成为了亟待解决的问题。
碳纤维布是一种单向碳纤维加固产品，通常采用12K碳纤维丝织造。碳纤维布强度高，密度小，厚度薄，基本不增加加固构件自重及截面尺寸，并且具有高耐久性，由于不会生锈，非常适合高酸、碱、盐及大气腐蚀环境中使用。
利用热可塑性树脂或热固化性树脂，可将碳纤维布与金属板加工成为一体化结构的复合金属板。该复合金属板能维持表面的金属材料特征而整体重量变轻，并且具有相同或更高之刚性强度。
发明内容
本发明所要解决的技术问题是提供一种高强航空复合金属板。
一种高强航空复合金属板，包括金属面板、金属芯板、金属背板和碳纤维布；
所述金属面板、金属芯板、金属背板之间铺设有碳纤维布；
所述金属面板的材质为碳钢；
所述金属芯板的材质为镁合金；
所述金属背板的材质为铝合金；
所述金属面板的厚度为1～1.5mm，所述金属芯板厚度为1.5～2mm，所述金属背板的厚度为1.5～2mm；
所述碳纤维布的厚度为1～1.5mm。
所述碳纤维布为缎纹或网纹。
本发明的有益效果是：保留航空用金属板原有的制作简单、造价便宜的优势，在金属板中加入碳纤维布，在充分满足使用要求情况下，获得强度更高、性能更好的航空复合金属板。
附图说明
图1是本发明结构示意图。
