Abstract

A hollow, pref. plastic shell, has regions selectively reinforced by zones which are reinforced by a rigid plastic foam. Pref. a sachet contg. the plastic and foaming agent is introduced into the shell in the required position and the plastic foamed so that it fills the shell in that region. The method is used particularly for strengthening boat hulls.
