Abstract
Official abstract text for this publication.
A preform manufacturing apparatus comprising a supply of fiber strip, a moveable positive fiber strip delivery mechanism coupled between a desired lay down location and the supply of fiber strip to positively deliver and orient the supply of fiber strip to the desired lay down location, and an electronic unwinder coupled to the supply of fiber strip is described herein. The electronic unwinder is configured to interact with the moveable positive fiber strip delivery mechanism.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: forming fabric strips from a wide stitch-bonded stretch broken carbon fiber fabric; positively transporting and placing a length of fiber strip to a desired orientation via a moveable fiber strip delivery mechanism interposed between a fiber strip supply and a desired lay down location of the fiber strip; controlling delivery of a fiber strip tension from the fiber strip supply using an electronic unwinder; and moving the moveable fiber strip delivery mechanism radially towards at least one of an inner diameter or an outer diameter of the desired lay down location by half the width of the fiber strips to interlock layers of a preform, wherein the moveable fiber strip delivery mechanism comprises a plurality of rollers on a common axis. 2. The method claim 1 , further comprising varying a circumferential speed of the electronic unwinder in response to readings of a sensor coupled to at least one of the moveable fiber strip delivery mechanism and the desired lay down location of the fiber strip.
