Composite structure manufacturing method for floor assembly e.g. floor of bus, involves injecting resin into main space between insulating layer and top layer in mold, where mold is opened and composite part is removed

摘要

The method involves providing a mold in a desired shape and size, and providing an insulating layer (20) in the mold. A top layer is provided in the mold, and the mold including the insulating layer and the top layer is closed. A resin is injected into a main space between the insulating layer and the top layer. The mold is opened and a composite part is removed. An independent claim is also included for a composite structure comprising an insulating layer.
