Abstract Scope |
Composite materials are becoming more and more prevalent with their clear advantages over traditional materials in both strength and weight. With composites being so widely used now, the ability to repair a composite has become crucial. Frontal polymerization is an emergent method of manufacturing composite materials that shows great promise in reducing the time and cost of producing thermoset-based fiber reinforced composite materials. This new method of manufacturing has other potential uses including being able to do in situ repair of damaged composites with only resin, carbon fiber, adhesive films and a UV-light-source. This repair capability is studied in our full paper.
In this paper, traditionally-manufactured carbon fiber epoxy composite plates are manufactured and then cut into standard sized strips. Some of these strips are then cut into two pieces to simulate a damaged composite plate. The cut specimens were then repaired with double lap joints using the same epoxy resin using either a traditional oven cure method or the novel UV-induced frontal polymerization method. All three specimens were then tested using a tensile tester to see how much strength each method of repair returns to the composite. |
