The Application of Ultraviolet Cure Resins for Repair of Composites.

摘要

This investigation has shown that it is possible to quickly, easily, and safely repair in the field damaged composites using UV curable resins. Although the best repair in this study restored 76% of the strength of the undamaged laminate, stronger repairs should be possible by optimizing the repair method. The nature of this study did not allow for a complete evaluation of all the variables which would affect the strength of these repairs. It is, therefore, reasonable to assume that stronger repairs would be possible by optimizing not only the resin system but also the method of cure (i.e. cure time, light intensity and wavelength), the surface preparation, and the reinforcing material.
