【摘要】：通過壓縮性能和剪切性能實(shí)驗(yàn),對同一密度的傳統(tǒng)芳綸紙蜂窩芯、開槽芳綸紙蜂窩芯以及有孔芳綸紙蜂窩芯的主要力學(xué)性能進(jìn)行了對比分析。實(shí)驗(yàn)表明,同一密度的傳統(tǒng)蜂窩芯的壓縮性能和剪切性能優(yōu)于兩種特殊蜂窩芯,但兩種特殊蜂窩芯的主要力學(xué)性能能夠達(dá)到傳統(tǒng)芳綸紙蜂窩芯標(biāo)準(zhǔn)中出廠檢驗(yàn)指標(biāo)值的77%以上,能夠滿足多數(shù)特殊結(jié)構(gòu)的使用要求。對兩種特殊芳綸紙蜂窩芯的制造工藝和實(shí)際應(yīng)用進(jìn)行了對比分析,指出了各自的優(yōu)勢和劣勢。兩種特殊蜂窩芯的W向剪切模量均高于指標(biāo)值。開槽蜂窩芯較有孔蜂窩芯制造工藝簡單、制造周期短、制造成本低,但有孔蜂窩芯制造精度更高、應(yīng)用范圍更加廣泛。
[Abstract]:The main mechanical properties of traditional aramid paper honeycomb core slotted aramid paper honeycomb core and porous aramid paper honeycomb core of the same density were compared and analyzed by compression and shear tests. The experimental results show that the compression and shear properties of the traditional honeycomb cores of the same density are superior to those of the two special honeycomb cores, but the main mechanical properties of the two special honeycomb cores can reach more than 77% of the factory inspection index in the traditional aramid paper honeycomb core standard. Able to meet the requirements of most special structures. The manufacturing process and practical application of two special aramid paper honeycomb cores are compared and analyzed, and their respective advantages and disadvantages are pointed out. The W shear modulus of the two special honeycomb cores is higher than the index value. The manufacturing process of slotted honeycomb core is simpler than that of perforated honeycomb core, the manufacturing period is short, the manufacturing cost is low, but the manufacturing precision of honeycomb core with hole is higher and the application range is more extensive.
