Abstract: Innovative structural applications using newer composites have been placing a greater demand on the development and performance evaluation of these materials. Fiber reinforced composites (FRC) appear to cater to the needs of several applications in which materials are required to perform under dynamic and impact loadings. The addition of fibers considerably improves the tensile, flexural, impact, fatigue and fracture resistance of the brittle concrete composites. The degree of improvement in these parameters depends on many factors including size, type, aspect ratio and volume fraction of fibers. In specific synergistic effects that can be achieved by the use of different fiber combinations is a matter great concern in recent years. As the reported works on hybrid FRC systems are limited, the precise ways in which the various fibers should be combined to produce this synergistic response, however, are not clearly understood. This paper presents a discussion on this subject along with the results of an investigation to understand the possible trends so that a direction can be obtained. The discussions are generally confined to mechanical, fracture and impact characteristics of hybrid FRC composites.
