Abstract The current research focus is on the study and synthesis of the deformation characteristic of epoxy plastic syntactic foams. In the current investigation, important to achieve good reinforcement properties as we know polymer vary in their chemical structure and offer different properties there selection of polymer matrix made based on application and property requirement. thermoplastics can used to make composites The resin plastic mixture (putty like consistency) which have high viscosities beyond 4 layer stops filtering and depends on the reinforcement used in the layer it is found that if polymer matrix is filled with fibrous materials the resulting material that is process very high and excellent mechanical properties these materials can be used for load bearing and other high end application such as material are composite materials there are two component themaincomponent ofthe composite is the matrix and second is component is reinforcement which is more often called as filler. The overpriced of artificial thermoplastic fibers like glass and carbon, etc. results ineffective and products obtained from these stuff which has demanded substitute resources of stuff advancement. This is also include the usage of nearby obtainable waste thermoplastics for materials stuff advancement. In this research, the main motive is to develop, investigate and determine the mechanical properties of the reinforcement material using waste thermoplastics. The fabrication of the composite was carried out using epoxyresin as the matrix and the waste thermoplastics as reinforcement. Tests were carried out to determinethemechanicalproperties such as tensile, hardness, impact and compressive strengths. The results were studied and compared with the conventional materials and it process that the material developed can be used in structural applications with strong dependence on its mechanical properties.

9. CONCLUSION

•Thestrengthofimpactandcompositematerialisdepends accordingtodifferentlayerofthermoplasticinimpacttest. Impact strength of different sample is grew with growing layer of Reinforcement up to 3 layer and then begin reducing.

8. RESULT

AfterperformingcompressiveTest,Thefollowingresultsare obtains

For without Reinforcement

FractureLoad=46.2kN

Cross sectionAreaofrectangularSpecimen

A=30*15=450mm2

So, Compressivestress=Fractureload/Area Compressivestress=(46.2×103)/450=102.66MPa

For Reinforcement uses

FractureLoad=56kN

Cross sectionAreaofrectangularSpecimen

A=30*15=450mm2

So, Compressivestress=Fractureload/Area Compressivestress=(56×103)/450=124.44MPa
