    Abstract: 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).
