Abstract
A system and method for repairing and/or strengthening a structure. The system may include an epoxy paste filler, a primer, an saturant/bonding adhesive, and a unidirectional carbon fiber. The method may include application of a paste filler, a primer, a bonding saturant and a unidirectional carbon fiber. The carbon fiber may be applied between application of a first bonding saturant layer and a second bonding saturant layer. The amount and/or length of the unidirectional carbon fiber may be based on the type of damage (e.g., the type and/or location of a crack) to the structure.
Claims14
A system for repairing and/or strengthening a porous structure comprising:
- a paste filler applied to a surface of the porous structure;
- a primer applied to the paste filler;
- a first saturant applied to the primer and the paste filler;
- a unidirectional carbon fiber material applied to the first saturant, over the paste filler and the primer;
- and
- a second saturant applied to said unidirectional carbon fiber material;
- wherein a roller device is applied to said first saturant and said second saturant for removing air bubbles from said first saturant and said second saturant,
- wherein the unidirectional carbon fiber material is formed into a first sheet and a second sheet,
- the second sheet is applied over the first sheet in an orientation along the surface that is perpendicular to the first sheet,
- the first sheet and the second sheet each extend across a crack in the surface,
- each of the first sheet and the second sheet has a first surface and a second surface opposite the first surface, the first surface of the first sheet and the first surface of the second sheet each face a surface of the porous structure,
- each of the first sheet and the second sheet cover portions of the surface of the porous structure on opposite sides of the crack, and
- the first surface of the second sheet covers the second surface of the first sheet.
