Definitions

  • peel ply a clean surface is formed using a peel ply cloth (hereinafter, peel ply).
  • peel ply a peel ply cloth
  • the quality may vary depending on the skill level of the worker, and the fibers may be damaged.
  • a peel ply composed mainly of polyester fibers is used. Since polyester does not adhere well to the matrix resin of the prepreg, it usually dissociates between the peel ply and the prepreg when peeled off after curing.
  • the polyester component may remain on the FRP surface, which may reduce the adhesiveness of the adhesive portion of the FRP panel.
  • the following means are adopted as the bonding pretreatment method for the composite material of the present disclosure.
  • the present disclosure is a pretreatment method for adhering a composite material to another member, wherein an absorbent body capable of absorbing a pollutant is attached to the surface of a prepreg laminate which is a precursor of the composite material.
  • the prepreg laminate is covered with a packaging material from above the absorber, the inside of the packaging material is evacuated, the prepreg laminate is heated at a temperature lower than the curing temperature of the prepreg, and then the packaging material is removed.
  • the absorber is peeled off, and a release member that does not transfer silicone and fluorine to the resin is attached to the surface of the prepreg laminate after the absorber is peeled off, and the prepreg laminate is cured to form a composite material.
