Abstract

PROBLEM TO BE SOLVED: To improve productivity by reducing the finishing process and to achieve highly accurate forming. SOLUTION: A cover is formed by first laminating a gel coat layer over an outer covering member mold which forms the outer covering member. Then, an FRP layer containing resin and fiberglass is laminated on the gel coat layer and hardened. Meanwhile, a gel coat layer is laminated on the inner covering member mold which forms the inner covering member and an FRP layer containing resin and fiberglass is laminated on the gel coat layer. While the surface of this FRP layer is still wet, this FRP layer and the FRP layer of the outer covering member are superposed on another for adhesion and hardening. Then, the inner covering member and the outer covering member are separated from the inner covering member mold and the outer covering member mold, respectively, to form the cover.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for forming a lid for a small boat.

[0002]

2. Description of the Related Art Small boats have, for example, lids for storage compartments and maintenance openings. These lids are obtained by laminating a gel coat layer on an inner lid member forming die for forming an inner lid member and curing the gel coat layer. Thereafter, an FRP layer is laminated on the gel coat layer and cured, and then the inner lid member is released from the inner lid member forming die. Similarly, the outer lid member is formed. The inner lid member and the outer lid member thus formed are adhered to each other, and the periphery thereof is trimmed and finished.

[0003] Incidentally, the inner lid member and the outer lid member are separated from the mold after being cured in the respective molds, and then adhered to each other.
