Abstract
Systems and methods for filament fastener that cures with composite part. One embodiment is a method of fabricating a composite part. The method includes placing layers of reinforcement fibers over a tool to form a laminate of composite material to be cured with a first resin, forming a filament fastener comprising bundled fibers with one or more texture elements around the bundled fibers, and coating the filament fastener with a second resin that is chemically compatible with the first resin. The method also includes inserting the filament fastener into the laminate through a plurality of the layers, and curing the filament fastener within the laminate to bind the plurality of the layers of the laminate with the one or more texture elements of the filament fastener via bonding of the first resin and the second resin to form the composite part with delamination resistance.
