Abstract

The occurrence of damage is considered as an unavoidable fact in fiber reinforced polymers. For this reason, the SELF-HEALING systems could extend the service life time of materials by implementing the concept of autonomous or induced repair. Herein, a SELF-HEALING E-glass fibers/epoxy composite based on MICRO-VASCULAR CHANNELS has been designed and fabricated. The specimens were fabricated via the hand lay-up route, while the fabrication of MICRO-VASCULAR CHANNELS was conducted through the removing of solid preforms. Due to the lack of previous studies about the utilization of anhydride resin hardener system with lower viscosity and also their controllable miscibility in comparison to the amine systems, in the present work, these materials were selected as healing agent for repairing the primary defects created in the structure. For this purpose, micro vascular channels containing two various parts of epoxy resin and anhydride hardener (2, 3.2, and 3.7 Vol.% with respect to the matrix part) were incorporated in the structure of composites. The flexural behavior of the specimens was assessed during the different time spans (0, 4, 8 and 11 days) from the primary damage creation. After the defect creation in the structure, the healing agents present in the micro vascular channels flow into the defects and after combining with catalysis dispersed in the matrix, local polymerization process and restoration of properties are started. According to the obtained results in this research, the highest FLEXURAL STRENGTH recovery of 46% was observed for the specimen with 3.2% healing agent after 8 days.
