Method and apparatus for the manufacture of fiber reinforced structures wherein tooling and a delivery head are employed for the placement of discrete, elongated fiber elements in mutually superimposed relationship to define reinforcement or stiffening members on fiber elements for the interiors or exteriors of composite shells and the consolidation of the fibers to form the cured composite structure. A consolidation medium is provided for the positioning and control of the fiber elements on the hard tooling and during the curing of the fiber elements.

[ What is claimed is:] [1.]1. A method of forming a composite structure by laying fiber elements on a work surface, said method comprising:providing an apparatus for laying said fiber elements on said work surface;providing hard tooling formed having a surface forming said work surface;providing a consolidation medium;laying a first fiber element having two mutually parallel sides along a first path on a portion of the surface of said hard tooling;laying a second fiber element having mutually parallel sides along a second path on a portion of the surface of said hard tooling intersecting the first path of the first fiber element on a portion of the surface of said hard tooling;terminating the second fiber element immediately adjacent a first side of the first fiber element with a terminal end surface of said second fiber element disposed at an angle parallel to the first side of the first fiber element;laying a third fiber element along the second path on a portion of the surface of said hard tooling from a location commencing immediately adjacent a second side of said first fiber element and with a commencing end surface of said third fiber element disposed at an angle parallel to the second side of said first fiber element; andcontacting a portion of said consolidation medium with a portion of said first fiber element.
