Low carbon emission and sustainable development are shared goals throughout the transportation industry. One way to meet such expectations is to introduce lightweight materials based on renewable sources. Sandwich panels with plywood core and fiber reinforced composite skins appear to be good candidates. Additional properties of wood such as fire resistance or thermal and acoustic insulation are also essential for many applications and could lead to a new interest for this old material. In this paper, Sandwich panels with two different types of plywood and four different skins (aluminum and glass, CFRP, or flax reinforced polymer) are tested under low-velocity/low energy impacts and their behavior is discussed.

低碳排放和可持续发展是整个运输行业的共同目标。满足这种期望的一种方法是引入基于可再生资源的轻质材料。具有胶合板芯和纤维增强复合材料外皮的夹心板似乎是不错的选择。木材的其他特性，例如耐火性或隔热和隔音性能，对于许多应用也是必不可少的，并且可能导致人们对这种旧材料产生新的兴趣。在本文中，在低速/低能量冲击下测试了具有两种不同类型的胶合板和四种不同的表皮（铝和玻璃，CFRP或亚麻增强聚合物）的夹芯板，并讨论了它们的行为。
