“…This function has been imparted to an FRP laminate by the incorporation of filled compartmentalised vessels, in the form of microcapsules [5][6][7] or hollow glass fibres [8][9][10]. This approach is reliant on an impact event to fracture the vessels and 'bleed' the contained mobile liquid phase into the damaged region.…”

International audienceThis study considers the embedment of a bioinspired vasculature within a composite structure that is capable of delivering functional agents from an external reservoir to regions of internal damage. Breach of the vascules, by propagating cracks, is a crucial pre-requisite for such a self-healing system to be activated. Two segregated vascule fabrication techniques are demonstrated, and their interactions with propagating Mode I and II cracks determined. The vascule fabrication route adopted played a significant role on the resulting laminate morphology which in-turn dictated the crack-vascule interactions. Embedment of the vascules did not lower the Mode I or II fracture toughness of the host laminate, with vascules orientated transverse to the crack propagation direction leading to significant increases in G and G through crack arrest. Large resin pockets were found to redirect the crack around the vascules under Mode II conditions, therefore, it is recommended to avoid this configuration for self-healing applications

“…Variety approaches have been proposed to improve the fragile feature of the epoxy resin, among which the incorporation of self-healing functionality [2][3][4] is very promising because of the toughening effect by the added healing agent carriers as micro-fillers [5] and the re-bonding of the induced micro-cracks timely upon their formation. Self healing in epoxy can be realized by various means in different scales, such as by layup of hollow tubes [6][7][8][9][10][11][12], fabrication of micro-vascular networks [13], microencapsulation [14][15][16][17][18][19][20][21], thermal additives [22], as well as molecular design by Diles-Alder reaction [23]. Attributed to the ease of manufacture and material integration, the embedment of microcapsules containing healants is the most popular approach among all the methods.…”

“…The healing liquid flows into the crack and restores the connection between the broken parts [2]. Selfrepair and damage assessment are of interest for concrete parts [3,4], polymers [5,6] and 3 related composites, as well [7][8][9][10]. Hollow fibers may also contain different "indicator" liquids, which can help us to detect the damage development.…”

2Hollow glass fiber reinforced epoxy matrix composites were produced to study whether the damage development can be followed and the self-repair can triggered by filling the fibers with suitable additives. Composite plates were manufactured by the hand layup and vacuum assisted resin transfer molding techniques. To detect subcritical transverse impact damage, hollow fibers were filled with an ultraviolet fluorescent dye, whereas for selfrepair, they were filled with a polyester resin along with the corresponding accelerator. The healing process was induced at different temperatures and continued for different durations. It was demonstrated that the targeted damage detection and self-repair can be achieved using thin (10-13 µm outer diameter) reinforcing hollow fibers. The selfrepairing ability was demonstrated in three point bending tests and the healing was confirmed by inspection with scanning electron microscopy.
