摘要/Abstract

摘要： 通过四点弯试验研究横向腹板增强复合材料夹层梁受弯性能,得到不同腹板间距、厚度对夹层梁弯曲破坏模式、刚度、极限承载力及延性性能的影响规律。结果表明:横向腹板能改变夹层梁的破坏模式,无腹板增强夹层梁破坏模式为芯材剪切破坏,横向腹板增强夹层梁破坏模式为多区格渐进破坏模式;相对于无腹板增强夹层梁,横向腹板能显著增强复合材料夹层梁的延性特性,最高达229%,腹板间距越小,夹层梁延性性能越好。

Abstract: This paper explores the flexural performance of sandwich beams with transverse ribs in four point bending tests. The effects of the thickness and space of the ribs on the failure modes, stiffness, ultimate bending strength and ductility properties of the sandwich beams were obtained. Test results indicates that the transverse ribs can change the failure mode of the sandwich beams. The beam without transverse ribs failed in core shear failure, while beams with transverse ribs failed in a more ductility failure mode. The transverse ribs can significantly increase the ductility properties of the sandwich beam with a maximum of 229%. The smaller the rib space, the better ductility performance.

Key words: composite material, sandwich beam, transverse ribs, bending performance, ductility
