از آن جهت که مواد کامپوزیتی به خصوص کامپوزیت‌ها با زمینه پلیمری ساختارهای آسیب‌پذیری نسبت به صدمات ایجاد شده در فرم ترک و شکستگی هستند. در سال‌های اخیر تلاش‌های علمی جدید در جهت ایجاد یک واحد کنترل داخلی صورت گرفته است، تا بتواند به صورت خودمختار در ترمیم کامپوزیت‌ها عمل کند. نام این نظریه خودترمیمی است. نظریه خودترمیمی ناشی از همسان‌سازی بیولوژییکی، نشان می‌دهد؛ همان‌گونه که عمیق‌ترین زخم‌ها وبریدگی‌ها به خودی خود ترمیم می‌شوند، می‌توان این ادعا را کرد که تمام مواد طبیعی قابلیت ترمیم ساختار خود را دارند. در این مقاله، مطالعه بر روی خواص میکروکپسول‌های موجود در کامپوزیت‌های خودترمیم پایه کپسولی مورد بررسی قرار می‌گیرد و هدف بررسی برهم‌کنش و انرژی ناشی از آن بین نانولوله‌های کربنی و پلیمر اوره‌فرمالدهید به عنوان ماتریس پایه در میکروکپسول‌های موجود در مواد خودترمیم پایه کپسولی، به روش تئوری تابع چگالی است. در ابتدا تأثیرات کایرالیتی و قطر نانولوله‌ها مورد بررسی قرار گرفت. پس از آن گروه‌های عاملی متفاوت بر روی نانولوله قرار می‌گیرند. در آخر میزان مدول یانگ که بر پایه‌ی ان;کرنشی
در محدوده‌ی تغییر شکل الاستیک قرار دارد، مورد محاسبه قرار گرفت
Since the polymer matrix composite structures of composite materials especially vulnerable to injuries in the form of cracks and fractures. In recent years, new scientific efforts have been made to create an internal control unit, to be able to act autonomously in composite restorations. The theory is resilient Biologically matched resilient theory of shows, just as the deepest wounds cuts to heal itself, can claim to be all natural substances have the ability to repair its structure. In this paper, the study on the healing properties of the microcapsules contained in the composite capsular base is examined and to investigate the interaction between carbon nanotubes and energy from urea formaldehyde polymer as the base matrix resilient material base in the microcapsules contained in the capsule, the method theory density function. At first the effect of chirality and diameter of the nanotubes was investigated. Then different functional groups on the nanotubes. Finally, the Young's modulus that is based on the strain energy in the elastic deformation range, was calculated
