Production Technology of Fiber-Reinforced RubCon

Introduction of fibers into composite materials influences not only their stress-strain characteristics but the manufacturing technology of these materials. The preparation process and workability of the mix depend on the percentage of fiber reinforcement (p) and the relative length of the fibers. 

One of problems of dispersed reinforcement of composites is a decrease of mixture workability at an increased reinforcement percentage and ratio between length of fibers and their diameter. The workability criterion is the mobility of the mixture, which was estimated by slump of the standard cone. 

Based on experiments, it can be concluded that application of fibers with a relative length of l/d = 100 is inefficient, especially at p 2%, because of the drastic reduction of the RubCon mixture workability and increased power inputs in the mixture preparation process. 

the basic stages of fiber-reinforced RubCon manufacturing techniques are
