为探讨由SW100/5228A玻璃纤维编织(GFRP)层板与CCF-1/5228A碳纤维复合材料(CFRP)层板以不同比例组成的功能梯度板的吸能性能,用重量80g直径23mm的弹丸对六种比例组成的功能梯度板进行了速度约70m/s的弹道试验。对弹击后的试样进行了损伤分析和剩余强度试验,通过C扫描发现,大面积损伤往往发生在中间层。随着玻璃纤维编织层厚度比例的增加,梯度板的吸能性能有所提高。通过对比背板变形发现,玻璃板厚度比例占5%的功能梯度板适合做结构的防弹装甲板材,而占30%比例的功能梯度板更适合作为人体防护板。
In order to investigate the energy absorption performance of functionally graded plates with different proportions of SW100 / 5228A GFRP laminates and CCF-1 / 5228A carbon fiber composite laminates (CFRP) Proportional composition of the function of the gradient plate speed of about 70m / s ballistic test. Damage analysis and residual strength test were carried out on the shots after the bullet, and it was found by C-scan that large-area damage often occurred in the middle layer. With the increasing proportion of the thickness of the glass fiber braid, the energy absorption of the gradient plate is improved. By comparing the deformation of the backplane, it is found that the functionally graded plate with the glass thickness ratio of 5% is suitable for the bulletproof armor plate with the structure, and the function gradient plate which accounts for 30% of the ratio is more suitable as the human body protection plate.
