Composites are materials which are widely used in aerospace industry for its high strength to weight ratio, where most of the alloys add weight as penalty. These composites are made up of two phases namely matrix phase and reinforcement phase. Matrix is the most important phase as it has to hold the reinforcement and to distribute the loads to the reinforcement i.e., the matrix should be adhesive and as well strong enough to resist de-bonding of reinforcement due to load acting on it. To improve certain properties of the matrix system fillers are added to it. Some filler may improve certain properties, while others reduce certain properties and improve some other properties. Combination of two or more fillers (hybrid filler system) can also be added to the matrix in certain proportion to improve its property. This work mainly concentrates on the effects addition of 1% by weight of hybrid fillers on the properties of the matrix system. Two selected filler system is mixed in the predefined proportion and added to the matrix system to prepare specimen. These specimens were tested for its flexural properties and compared with the neat matrix system.
