Sürekli elyaf takviyeli termoplastiklerin mekanik ve termal özellikleri

In this study the composite materials explained first. Then some general thoughts about thermoplastic and thermoset based composites were given. General information about the developments of production methods for the continuous fiber reinforced thermoplastic composites was given.The thermal conductivity and mechanical properties such as tensile strength, elongation at break, modulus of elasticity, flexural and impact properties of composites are investigated experimentally. After then the test results are compared with existing theories. First of all continuous fiber reinforced thermoplastic prepreg tape production process is developed to make these thermoplastic composite specimens. Unidirectional carbon and glass fiber reinforced polypropylene prepreg were produced using this process.Tests were grouped in two sections as mechanical and thermal. Tensile, flexural and impact tests were applied which are common tests for mechanical properties. Transverse thermal conductivity tests were made with the specimens for thermal tests. Test results were compared with theoretical models which are also explained detailed within the tests.In addition these tests, SEM photographs were taken both prepreg materials with different magnification to understand matrix-fiber interaction.
