摘要：

研究了缝合及加强筋增强方式下泡沫夹芯复合材料的三点弯曲性能。采用万能试验机分别进行了缝合与未缝合碳纤维、玻璃纤维、玻碳混杂纤维泡沫夹芯复合材料的三点弯曲实验，分别得出各自的载荷-挠度曲线，再引入加强筋的方式进一步研究缝合碳纤维泡沫夹芯复合材料的弯曲性能。结果表明，玻碳混杂纤维泡沫夹芯复合材料较玻璃纤维泡沫夹心复合材料性能有所提升；引入加强筋会使缝合碳纤维泡沫夹芯复合材料的弯曲强度从17.79 MPa增大到37.47 MPa，且随着加强筋数量增多，缝合碳纤维泡沫夹芯复合材料的弯曲性能得到提升；在加强筋数量相同（2根）的情况下，加强筋平行铺放时弯曲性能最好，弯曲强度达到46.96 MPa，20 °交叉铺放时次之，十字铺放时最差。

Abstract:

This paper reported an investigation on the three-point bending properties of the foam sandwich composites prepared through stitching and rib reinforcement methods. A three-point bending experiment was carried out with a universal testing machine for the seamed and unstitched carbon fiber， glass fiber， and glass-carbon hybrid fiber foam sandwich composites， with the corresponding load-deflection curves presented in the paper. The flexural properties of the seamed carbon fiber foam sandwich composites were further studied by means of a reinforcing rib method. The results indicated that the performance of the glass-carbon hybrid fiber foam sandwich composites was improved in comparison with the glass fiber foam sandwich composites. The introduction of reinforcing ribs increased the bending strength of the stitched carbon fiber foam sandwich composites from 17.79 MPa to 37.47 MPa. The bending performance of the stitched carbon fiber foam sandwich composite was improved with an increase in the number of reinforcement ribs. At the same number of reinforcement ribs， the sandwich composites achieved optimum bending strength of 46.96 MPa when the reinforcement ribs were laid in parallel. Next was under the 20 ° cross-laying of the reinforcement ribs and least was under the cross-laying of the reinforcement ribs.

Key words: foam sandwich structure, fiber reinforcement, matrix rib, flexural behavior
