1. A composite laminate comprising:
layers of reinforcement fibers forming a stack of composite material to be cured with a first resin; and
a filament fastener including bundled fibers with one or more texture elements around the bundled fibers, and a second resin chemically compatible with the first resin, wherein the one or more texture elements spiral around the bundled fibers to form a helical shape, wherein the helical shape of the filament fastener has a pitch that corresponds with a thickness of each layer of the composite laminate,
wherein the filament fastener is configured to insert into the stack through a plurality of the layers of reinforcement fibers, and to cure within the stack to bind the layers of the stack 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 laminate with delamination resistance.
