The development of self-healing materials is now being considered for real engineering applications. Over the past few decades, there has been a huge interest in materials that can self-heal, as this property can increase materials lifetime, reduce replacement costs, and improve product safety.

Joseph F. Schevtchuk Follow. Polymer matrix composites PMCs utilize thermoset resins in large part because of their low starting molecular weights which allow for good reinforcement infiltration prior to curing. Formed networks owe much of their mechanical properties to covalent crosslinks tethering molecules within the matrix. Traditional covalent bonds are irreversible and thus damaged composites are either repaired or replaced. For the former, traditional repair techniques remain costly and time consuming.

We demonstrate for the first time the direct stereolithographic 3D printing of an extrinsically self-healing composite, comprised of commercial photocurable resin modified with anisole and PMMA-filled microcapsules. This work illustrates the potential of stereolithographic printing to fabricate self-healing composites with user-defined structures, avoiding the need for extensive rheological optimization of printing inks, like in direct-write 3D printing.

Self healing in polymers and polymer composites. Concepts, realization and outlook: A review

Polymers are widespread in different sectors, from packaging to construction. In this scenario among emerging polymers there are self-healing polymers that falls into the class of smart polymers [5]. It is considered that in these compounds could carry to4. These groups can form oxidative products or rearrange themselves to repair the leak.

Self-healing polymers and composites utilizing the Diels—Alder reaction have received considerable attention due to the intrinsic healing capability of this crosslink. However past research focused on chemistries that cleave at low temperatures, which places limitations on the polymer's use temperature.

Это был шантаж. Все встало на свои места. - Ну конечно, - сказала она, все еще не в силах поверить в произошедшее.

Над головой, в головокружительном пустом пространстве, на потрепанной веревке раскачивалась серебряная курильница размером с холодильник, описывая громадную дугу и источая едва уловимый аромат. Колокола Гиральды по-прежнему звонили, заставляя содрогаться каменные своды. Беккер перевел взгляд на позолоченную стену под потолком. Его сердце переполняла благодарность.

Компьютер зафиксировал ее прибытие. Хотя Сьюзан практически не покидала шифровалку в последние три года, она не переставала восхищаться этим сооружением. Главное помещение представляло собой громадную округлую камеру высотой в пять этажей. Ее прозрачный куполообразный потолок в центральной части поднимался на 120 футов. Купол из плексигласа имел ячеистую структуру - защитную паутину, способную выдержать взрыв силой в две мегатонны. Солнечные лучи, проходя сквозь этот экран, покрывали стены нежным кружевным узором. Крошечные частички пыли, пленницы мощной системы деионизации купола, простодушно устремлялись вверх широкой спиралью.
