Composite fuselage frames and methods of fabricating frame fillers and composite fuselage frames for aircraft

A composite fuselage frame for an aircraft, comprising:

• a web comprising a width and a first predetermined thickness and forming an arc between a first end and a second end in relation to a fuselage of the aircraft, the width extending from an outer side in relation to a skin on the fuselage to an inner side;
• and
• a shear tie foot disposed on the outer side of the web between a first mouse hole and a second mouse hole and projecting from the first predetermined thickness of the web, the shear tie foot having a second predetermined thickness that extends along the skin of the aircraft between a first stringer and a second stringer, and
• wherein the second predetermined thickness of the shear tie foot is defined by the first predetermined thickness and a second plurality of second polymer matrix composite layers formed by a plurality of first material polymer matrix composite plies that provide a frame filler integrated with a plurality of second material polymer matrix composite plies of the first predetermined thickness.
