Title:
熱可塑性強化ダクト及びその製造
Document Type and Number:
Japanese Patent JP7076179
Kind Code:
B2
Abstract:
Duct segments that define a channel for conveying a fluid, where the duct wall includes a sheath of reinforcing fabric incorporating multiple reinforcing fibers, and a thermoplastic fused with the sheath of reinforcing fabric. The duct segments may be prepared by wrapping a mandrel configured to define the inner mold line of a desired duct segment with a thermoplastic film, enveloping the wrapped mandrel with a reinforcing sheath incorporating reinforcing fibers; wrapping the enveloped mandrel with another thermoplastic film to form a multilayer duct segment precursor; enclosing the mandrel and multilayer duct segment precursor within an outer mold defining the outer mold line for the desired duct segment; heating the duct segment precursor at a temperature and for a time sufficient to fuse the layers of the multilayer duct segment precursor; and then cooling the resulting duct segment.
