SELF-HEALING COMPOSITE MATERIALS WITH A NOVEL MICRO VASCULAR APPROACH

Abstract
Abstract - Problem Statement In microvascular self-healing materials, the vascular channels used as a carrier system for self-healing agents should be manufactured as an integral part of the sandwich core,withstand mechanical loads, and be lightweight. In addition to these characteristics, the channels must ensure the leakage of the healing agent in the damaged area, and there must be an activator as the required amount of healing agent polymerization in the cracked areas. Methods This study employed dense polysulfone-based channels with a continuous vein structure in epoxy reinforced with a maximum of 10% carbon fiber powder. The self-healing capabilities of damaged samples were evaluated through impact testing. Results Due to the porous membrane structure of the polysulfone (PSU) fiber channel wall, the delivery of a healing agent to a damaged area has been identified as a novel solution. The healing agent's accessto the damaged area was facilitated using a multiple-channel structure. With the use of carbon fiber powder as a CA activator in the matrix not only resulted in rapid curing but also presented mechanical properties enhancement. Conclusions This study presented a matrix structure that contains the activator of the healing agent and has microvascular channels that provide self-healing by transferring the healing agent to the crack area from the vascular pathways. It has been shown that it can be a life-enhancing and repetitive self-healing solution in all areas where sandwich structures and composite materials are used.
