- 摘要:
- 传统的夹芯结构复合材料通常是将面板和芯材粘结在一起，这使得夹芯结构芯材与面板的界面性能薄弱。为了弥补现有夹芯结构材料界面性能薄弱的缺点，研究了缝纫增强泡沫夹芯结构复合材料一体化成型工艺，并对其力学性能进行了试验研究。通过与未缝纫泡沫夹芯结构的对比试验，发现缝纫能显著提高泡沫夹芯结构的弯曲强度、平压强度和侧压强度，而且随着缝纫密度的增加，该夹芯结构的抗弯、平压和侧压性能均有提高。
- Abstract:
- Traditional composite sandwich structures are constructed by bonding the laminated skin and the light weight core material together, which leads a weak mechanical performance at the skin-core interface. To deal with the property defects of the weak interface in the present sandwich structures, the skin-core integration molding technology for enhancing the foam composite sandwich structure by stitching is studied, and the mechanical properties of this novel sandwich structure are tested. The comparison test of the unstitched and stitched foam composite sandwich structures shows that the stitching can significantly improve the flexure strength, flatwise compressive strength and edgewise compressive strength. In addition, the capaci
