The photocurable resin system and reinforcing materials (chopped strand mat, glass fiber cloth, etc.) are impregnated and molded in advance, and the surface is covered with a plastic film or release paper to obtain a photocurable prepreg semi-finished product with uniform thickness.
Characteristics of light-curing prepreg resin
Good light curing property; can be thickened; good wettability* Depending on the preparation process, the prepreg can be prepared into
The preparation of the light-curing hose is to pour the light-curing resin system into the dry tube, and then roll it through a drum to make the resin infiltrate the fibers and make the thickness uniform.
Application of light-curing prepreg
1)Heat and cold insulation
2)Pipeline protection
3)Fiberglass products
UV-CIPP repair: an emerging method for repairing underground pipe networks.
Other applications of photocurable resins in composites
Based on the advantages of fast curing and controllable reaction of photocurable resins, they can also be used in areas such as gas cylinder winding and wind turbine blade repair.
