Due to their lighter weight, greater strength and durability, the use of polymer composites for multiple applications such as automotive, aerospace, défense, marine and other industries is becoming extremely advantageous. To reduce the price of resin and/or improve its physical characteristics, inert materials added to composites, called filler. Fly ash is also commonly used as filling material now a day. The purpose of the current job was to assess the impact on the characteristics of hybrid polymer matrix composites based on epoxy resin reinforced with glass fiber by adding fly ash as filler. The composites of the hybrid polymer matrix were manufactured using the easy technique of hand lay-up followed by curing in the compression moulding machine. The percentage of fly ash particles in the epoxy matrix ranged from 5, 10 and 15 percent by adding 4 layers of woven glass fiber mat for hybrid composite manufacturing. Dynamic mechanical analysis (DMA) was then subjected to the manufactured composites. DMA is a strong method for characterizing polymers and composites viscoelastic characteristics. The results show that the fly ash-filled epoxy composites storage modulus and loss modulus increase considerably with the addition of up to 10 wt percent of fly ash. The fly ash can therefore be used as one of the low-cost reinforcing fillers for epoxy composites reinforced with glass fiber. The flexural modulus shows increasing trend but flexural stress first decreases then increases alternately. The peak flexural stress is at 20 wt percent fly ash. The tensile stress reduces up to 15 wt percent fly ash. At 20 wt percent fly ash, the value of tensile stress is maximum and then it reduces again. Tensile modulus is maximum at 20wt% of fly ash.
