Description

一种高强航空胶合板
技术领域
本发明涉及一种航空胶合板，具体地说，是一种高强航空胶合板。
背景技术
航空胶合板(aircraft plywood)由材质均匀、强度高的木材旋制的薄单板用酚醛树脂胶胶合而成的室外型胶合板。航空胶合板材质均匀，胶合性能好，容重轻，机械强度高，应用于飞机、滑翔机和靶机制造中。但是航空胶合板存在胶合厚度与胶合强度之间的矛盾，若想获得强度高的胶合板就需要增加胶合板的层数，这就增加了航空胶合板的厚度与重量，因此在满足容积与重量要求情况下，如何提高航空胶合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。
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胶合板。
一种高强航空胶合板，包括面板、芯板、背板和碳纤维布；
所述面板、芯板、背板之间铺设有碳纤维布；
所述面板、芯板、背板的材质为白桦木；
所述面板的厚度为3～3.5mm，所述芯板厚度为3.5～4mm，所述背板的厚度为3.5～4mm；
所述碳纤维布的厚度为1～1.25mm。
所述碳纤维布为平纹，斜纹，缎纹或网纹。
本发明的有益效果是：本发明保留了航空胶合板原有的制作简单、造价便宜的优势，在胶合板中加入碳纤维布，在充分满足使用要求情况下，获得强度更高、性能更好的航空胶合板。
附图说明
图1是本发明结构示意图。
