Project no. 553 · Status: Kapanmış · 2017
Summary
The main concern in the thermal energy storage systems is the storage and usage of thermal energy at the time when it is available and required, respectively. Polymeric energy storage materials are materials that are used to store thermal energy in many building applications. In this study, effect of phase change materials on thermal, mechanical, and physical properties of thermoplastic composites was investigated. Polypropylene (PP) as a polymer matrix and 2 types of paraffin waxes (RT5HC and RT18HC) as phase change materials (PCM) were used to manufacture PCM filled PP composites. Composite granules were obtained by adding RT5HC and RT18HC at various weight fractions (20, 30, 40%) into PP with twin screw extruder. Test specimens were produced by injection molding of these composite granules. The effect of PCMs on thermal, mechanical and physical properties of composites were studied by several In this study, effect of phase change materials on thermal, mechanical, and physical properties of thermoplastic composites was investigated.

Test specimens were produced by injection molding of these composite granules. The effect of PCMs on thermal, mechanical and physical properties of composites were studied by several characterization techniques such as Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), Thermomechanical Analysis (TMA), Melt Flow Index (MFI), HDT Vicat, Tensile and Flexural Tests, Notched and Unnotched Impact Strength Tests, and Density Analysis. It has been demostrated that PCMs improved thermal properties and energy capacity of PP composites. PP composites with PCMs have a great potential to be used in room temperature applications with high thermal efficiency. characterization techniques such as Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), Thermomechanical Analysis (TMA), Melt Flow Index (MFI), HDT Vicat, Tensile and Flexural Tests, Notched and Unnotched Impact Strength Tests, and Density Analysis.
