Abstract
The thermoset polymers and the thermoplastic polymers matrix composites require different forming techniques due to the different properties of two classes of polymers. While the forming technique for thermoset polymer matrix composites does not require the use of special equipment, the thermoplastic polymer matrix composites imposes the rigorous control of temperature and pressure values. Each type of polymer transfers to the composite a set of properties that may be required for a certain application. It is difficult to design a composite with commonly brittle thermoset polymer matrix showing properties of a viscoelastic thermoplastic polymer matrix composite. One solution may consist in mixing a thermoset and a thermoplastic polymer getting a polymer blend that can be used as matrix to form a composite. This study is about using PMMA solutions to obtain thermoset-thermoplastic blends and to mechanically characterize the obtained materials. Three well known organic solvents were used to obtain the PMMA solutions, based on a previous study concerning with the effect of solvents presence into the epoxy structure.

The nowadays life is depending more and more on the characteristics of materials that are used to produce high quality goods
In a prior study we have developed an investigation regarding the possibility to change the basic properties of an epoxy resin using well-known organic solvents [1]
That is why the present study concerning with the mechanical properties of the named epoxy resin when some quantities of PMMA solution in the three solvents are used as modifying agents is connected to the previous study
Summary
The nowadays life is depending more and more on the characteristics of materials that are used to produce high quality goods. The thermoplastic polymers are processed at relatively elevated values of the temperatures and require special equipment with a high level of parameters control in order to obtain quality materials. In this case the raw materials are cheaper and their waste is recyclable – as is the case of polyethylene terephthalate but, . To form composites with thermoplastic polymer matrix is more difficult because the presence of a structure (what will become the reinforcement of the composite) inside the mold is increasing the need of parameters control
