A method for preparing a modified rubber introduces a reactive group into a high-performance short fiber by irritating the short fiber by ultraviolet light, and modifies the short fiber by a coupling agent to increase the compatibility of the short fiber with a rubber matrix, and finally, utilizes the charge repulsion of sodium lauryl sulfate to effectively avoid the agglomeration of the short fibers in the rubber matrix, which is benefit for obtaining the modified rubber. The present disclosure further provides a modified rubber prepared by the method and a bulletproof and puncture resistant tire prepared by the modified rubber, wherein a buffer layer is made by the modified rubber, and at least one of a tread, a belt ply and an inner liner is made by the modified rubber, and a cord ply is woven by twisted high-performance long fibers.

Methods of forming a lightweight reinforced thermoplastic core layer and articles including the core layer are described. In some examples, the methods use a combination of thermoplastic material, reinforcing fibers and bicomponent fibers to enhance retention of lofting agents in the core layer. The processes permit the use of less material while still providing sufficient lofting capacity in the final formed core layer.
