A METHOD OF MANUFACTURING STIFFENED SINGLE-SHELL AND SANDWICH CONSTRUCTIONS FROM REINFORCED PLASTICS.

摘要

A method of manufacturing stiffening members or attachment members (5), preferably in boat hulls made from plastics, which attachment members (5) are to serve to secure frame ribs, stringers and similar members. According to the method, indentations (3) have been formed in the mould (2) on which the boat hull is to be built and the attachment members are built up as laminates whereupon the indentations (3) forming the attachment members are sealed with plugs (7), allowing the boat hull to be then built up, its surface being smooth and unbroken.
