چکیده

با افزایش روز افزون کارایی مواد نانو و نانو کامپوزیت‌ها در زندگی روزمره و صنعت، تحقیقات گسترده ای در این زمینه آغاز شده است. به همین دلیل در راستای تحقیقات گذشته و تکمیل آن‌ها مواد نانو لوله کربنی و نانو گرافن به طور جداگانه با درصد وزنی های1/0، 3/0 و 5/0در فاز زمینه کامپوزیت متشکل از رزین اپوکسی و الیاف بازالت اضافه گردید و به روش لایه گذاری دستی نانو کامپوزیت‌های شش لایه الیاف بازالت ساخته شد. در ادامه نمونه‌های کامپوزیتی و نانو کامپوزیتی برای تعیین میزان تغییرات انرژی جذب شده شکست، تحت آزمون ضربه شارپی قرار گرفت و سطح شکست نمونه‌ها پس از انجام آزمون ضربه شارپی برای مطالعه دقیق و کامل، تحت عکس برداری الکترونی قرار گرفت. افزایش میزان انرژی ضربه جذب شده درحضور مواد نانو با تمامی درصد وزنی های متفاوت نسبت به نمونه کامپوزیتی مشاهده گردید. بیشترین میزان افزایش انرژی ضربه جذب شده در نمونه‌های نانو کامپوزیت نسبت به نمونه های کامپوزیت، در نمونه هایی استفاده شده از ذرات گرافن به میزان 1/0 درصد وزنی مشاهده گردید. بیشترین میزان افزایش انرژی ضربه جذب شده در نمونه های کامپوزیت های نانولوله کربنی، مربوط به استفاده از 3/0 درصد وزنی از نانو لوله کربنی در فاز زمینه می‌باشد.

چکیده [English]

As the nanoscale materials and nano-composites are increasingly used in everyday life and industrial applications, extensive research has begun into this field. For this reason, in the course of previous research, carbon nanotubes and nano-graphene materials were added separately with weight percentages of 0.1, 0.3 and 0.5 in the composite phase consisting of epoxy resin and basalt fiber, and nano-composites laminates with 6 layers of basalt fiber were made through hand layup. In order to determine the amount of energy absorbed during impact, composite and nanocomposite samples were subjected to Charpy impact test, and the specimen deformations were studied under electron microscopy. An increase in the energy absorbed by samples containing nanoscale materials with all weight percentages was observed in comparison with conventional composite specimens. The highest increase in absorbed energy in nanocomposite samples with regard to the composite specimens was observed in samples containing 0.1% graphene particles by weight. The highest increase in absorbed energy in carbon nanotubes composites was detected in samples consisting of 0.3% carbon nanotubes in the matrix.
