A nylon 11 composite system has significantly improved flexural modulus while keeping or even increasing the impact strength. This composite system may comprise a nylon 11/filter/modifier. The flexural modulus and impact strength increases over 150% and 80%, respectively compared with neat nylon 11. The “ball” portion of badminton shuttlecocks made by this type of composite may more closely duplicate the flight capabilities of natural duck feather shuttlecocks than nylon 11. The nylon 11/filler/modifier ay allow for a very close duplication of the restoration effects of shuttlecocks made from feathers therefore providing a product which can be a one for one aerodynamic performance substitution for the natural product (feathers).

Claims
1. A composite comprising nylon 11, a filler, and a maleic anhydride grafted modifier.
2. The composite as recited in claim 1, wherein an content of the nylon 11 is 20-98 wt. %, a content of filler is 1-50 wt. %, and a content of the modifier is 1-60 wt. %.
3. The composite as recited in claim 1, wherein the filler comprises one or more of the following: organic clay, inorganic clay, graphite, carbon black, C60, carbon nanotubes, carbon fiber, ceramic, glass fiber, or any other metallic, semiconductive, and insulating particles.
4. A badminton shuttlecock comprising a composite material of nylon 11, a filler, and a maleic anhydride grafted modifier.
5. The badminton shuttlecock as recited in claim 4, wherein the filler comprises one or more of the following: organic clay, inorganic clay, graphite, carbon black, C60, carbon nanotubes, carbon fiber, ceramic, glass fiber, or any other metallic, semiconductive, and insulating particles.
