بررسی تجربی نفوذ شبه استاتیکی چند لایه های فلز – کامپوزیت تقویت‌شده با نانو سیلیکا

FMLs are considered by many industries, including the aerospace industry, due to their important advantages such as high strength, low weight, corrosion and moisture resistance, good fatigue properties, and so on. The purpose of the present study is to improve the mechanical properties of the panel through the addition of nanoscale by improving the structure of the FML. For this purpose, the percentages of different weights of nano silica (0, 0.3, 0.6, 0.9% relative to the field) by Magnetic and ultrasonic mixing methods in the FML structure consisting of aluminum 2024 and fiber glass and hybrid added became the mechanical behavior of the samples was investigated by a quasi-static penetration test with spirometer. The results showed that Nano-FML panel samples had better inversion behavior compared to the control sample (without adding nano phase) and the highest improvement in strength was observed with a 0.6% nano silica sample with glass fibers and 0.3% w / w of nano silica with hybrid fiber are observed.
