Description

木基压电层合板
技术领域
本实用新型属于智能结构材料产品。
背景技术
木质材料是当今建筑业中用途较为广泛的结构材料之一,具有较多优点。但是,在使用中由于受外界负载、温度和湿度变化的影响,可能导致木质结构发生变形,这种变形若超过一定限度则可能对结构安全造成危害。另一方面,压电陶瓷材料具有正、逆压电效应,既可用于监测结构变形又可在电场作用下产生一定的驱动力。
发明内容
本实用新型的目的就是设计提供一种木基压电层合板,通过压电陶瓷层的正、逆压电效应分别达到监测结构变形和抵抗变形的作用。
本实用新型的基本设计是,木基压电层合板由木材单板和压电陶瓷构成,在相邻的两层木材单板之间配置安装一层压电陶瓷;木材单板的厚度为5-50毫米;压电陶瓷的厚度为2-10毫米。
附图说明
附图是木基压电层合板结构示意图。
图中件号说明:
1、木材单板、2、压电陶瓷
具体实施方式
下面结合附图对本实用新型最佳实施方案进行详细描述。木基压电层合板,该板由木材单板1和压电陶瓷2构成,在相邻的两层木材单板之间配置安装一层压电陶瓷;木材单板的厚度为5-50毫米;压电陶瓷的厚度为2-10毫米。
制造时,将木材单板1与压电陶瓷2层合排列组坯,在层间涂环氧树脂胶粘剂,在热压机中热压制成。本复合板可用于建筑领域。
