Abstract
A method of repairing or reinforcing a target structure includes preparing an adhesive sheet having at least an adhesive layer and a repairing or reinforcing material, irradiating the adhesive sheet with ionizing radiation, and attaching the adhesive layer to the target structure after the irradiation with the ionizing radiation.
Claims20
A method of repairing or reinforcing a target structure comprising the steps of:
- preparing an adhesive sheet comprising at least an adhesive layer having a first side and a second side, and a repairing or reinforcing material;
- irradiating the adhesive sheet with ionizing radiation so as to initiate a curing reaction of the adhesive layer;
- and
- attaching the first side of the adhesive layer to the target structure after the irradiating step.
