FILAMENT FOR EXTRUSION-BASED ADDITIVE MANUFACTURING SYSTEM
20180001585 · 2018-01-04 ·

A filament is fed to an extrusion head. The filament has a semi-crystalline polymeric reinforcement portion and a polymeric matrix portion. The reinforcement and matrix portions run continuously along a length of the filament. The reinforcement portion has a higher melting point and a higher crystallinity than the matrix portion. The temperature of the filament is raised in the extrusion head above the melting point of the matrix portion but below the melting point of the reinforcement portion so that the matrix portion of the filament melts within the extrusion head, thereby forming a partially molten filament within the extrusion head. The partially molten filament is extruded from the extrusion head onto a substrate, the reinforcement portion of the partially molten filament remaining in a semi-crystalline state as it is extruded from the extrusion head. Relative movement is generated between the extrusion head and the substrate as the partially molten filament is extruded onto the substrate in order to form an extruded line on the substrate. The matrix portion of the extruded line solidifies after the extruded line has been formed on the substrate.

Method of forming a headliner that includes shaped reinforcement brackets

A method of forming a headliner for a vehicle includes forming the headliner into a desired shape from one or more materials. The headliner includes a headliner cutout portion corresponding to an opening through the headliner. A reinforcement bracket preform is formed into the headliner cutout portion during the step of forming the headliner. The headliner cutout portion is removed from the headliner. The reinforcement bracket preform is removed from the headliner cutout portion and a shaped reinforcement bracket is formed.
