Abstract
Official abstract text for this publication.
A method of manufacturing a composite core can include: wrapping a mandrel in a mandrel wrapping process by securing a mandrel with a winding jig; orienting the composite material at a wrap angle to the mandrel; and depositing the composite material around a circumference of the mandrel. The method can further include assembling the wrapped mandrels in a tool and applying a pressure to the composite material during a curing cycle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing a block of a composite core having a plurality of hexagonal shaped cells, the method comprising: securing a hexagonal mandrel with a winding jig; cutting a slit of composite material to a prescribed width, the prescribed width being dependent upon a wrap angle of the slit of composite material to the hexagonal mandrel and being dependent upon a circumference of the hexagonal mandrel; orienting the slit of composite materia…
