Self-healing efficiency for fiber reinforced polymer composites
Journal Title: Jurnalul Stiintific TURBO - Year 2017, Vol 4, Issue 2
Abstract
The paper presents a study on self-healing behaviour of fibre reinforced composite materials integrating dicyclopentadiene filled urea-formaldehyde microcapsules as healing system and Grubb’s catalyst as reaction catalyst. Microstructural analysis showed the formation of microcapsules with diameter ranging from 100 μm to 200 μm. Composite samples were manufactured using prepreg plies and 5%wt. Grubb’s catalyst and 10%wt. microcapsules and subjected to three point bending flexural test (according to SR EN ISO 14125). Samples showed a healing recovery of 87-94% after second loading, after they were left at 35o-40oC for the healing to take effect.
