摘　　要：设计并采用热压罐方法生产了由复合材料面板和铝泡沫芯子组成的复合材料夹芯梁,对其在简支边界条件和三点弯曲受载下的失效模式及弯曲刚度进行了实验研究。研究发现:与其他3种常见的金属泡沫芯子金属面板夹芯结构相比,自行设计的面板为层合板的金属泡沫复合材料夹芯结构具有较高的弯曲比刚度、明显的重量优势及可设计性。Composite sandwich beams comprising composite faces and Al cores have been designed and manufactured by the autoclave cure process. The quasi-static three-point bending response of simply supported composite sandwich beams is measured by experiment. This investigation is concerned with the collapse response and flexural stiffness of simply supported composite sandwich beams with metal foam cores, the deformation and failure behavior is also explored. The experimental investigation reveals that the failure mode of sandwich beams is face yield. Compared to the other three common metal foam sandwich structures with metal faces, the bending specific stiffness of metal foam sandwich structure with composite faces is higher.
