1月14日上午10点30分，由土木工程学院和力学技术研究院联合举办的“力学技术讲堂”之“超级木头－可能代替钢材的未来结构材料之星”学术报告会在土木楼212报告厅举行，主讲人为美国马里兰大学李腾教授，土木工程学院副院长苏明周教授主持本次会议。
李腾教授作报告
报告会伊始，力学技术研究院院长、首席科学家、南非科学院院士孙博华教授介绍了李腾教授的基本情况。李腾教授在报告中主要讲解了一种新型材料－Super Wood（超级木头），即将天然原木通过简单而有效的处理，在热压后从天然木材中部分去除木质素和纤维素，可将大块天然木材直接转化为强度、韧性和抗冲击性较之前增加10倍以上的结构材料，且通过这一方法对不同种类的木材处理之后都获得普遍效应。李教授经过反复实验试验，发现由此产生的轻质致密的木材具有创纪录的高机械强度和断裂韧性，其比强度超过了几乎所有的结构金属和合金材料。这种高性能、低成本且绿色环保的超级木头为未来的建筑应用提供了一个新的前景和发展途径。李腾教授对这种材料提出设想，有望在未来实践应用于汽车、飞机等制造及建筑工业等更为广阔的领域中。
提问环节
随后现场师生对报告内容提问，李腾教授认真细致的为他们进行了相应的讲解。最后，孙博华院士针对本次报告进行总结点评，他肯定了李腾教授的科研成果，同时对在座的师生提出期望，希望大家可以从本次报告会中有所认识、有所收获、有所启发，在自己的科研领域做出丰硕的成果。
孙博华教授总结点评
此次报告会虽然短暂，但李腾教授给同学们带来了积极深远的影响。他提出的“超级木头”让同学们了解了领域前沿，极大地提升了同学们对科研的兴趣，启发了同学们的科研思路，同时他本人对学术研究的治学态度和科学严谨的思维方法让同学们收获颇丰。
本次研究报告会为土木工程学院师生提供了良好的学术交流平台，有利于提升全院学生综合素质。同时对于全院师生准确把握国际热点研究方向、扩展国际视野具有重要意义，对我院学科专业的建设发展具有重要的促进作用。
