研究目的
To create polymer matrix composites with polyester and vinyl ester for better heat resistance and investigate their mechanical properties and heat distortion temperature for solar panel applications.
研究成果
The study successfully produced polymer matrix composites of various blends of vinyl ester and polyurethane. The heat distortion temperature for each sample was found using the heat distortion unit, and the readings were arranged and compared by graph. The proportion 80% vinyl ester and 20% polyurethane showed good flexibility and sturdiness compared to other proportions, making it suitable for solar panel board applications.
研究不足
The extent 40:60 and 20:80 does not form as flawless IPN, indicating limitations in achieving perfect interpenetrating polymer networks with these proportions.
1：Experimental Design and Method Selection:
The study aimed to create polymer matrix composites with polyester and vinyl ester for better heat resistance. The glass fiber with polyester was favored with various pieces of composite with the addition of various fillers in various weight parts. The composites were created using a vacuum bag shaping procedure.
2：Sample Selection and Data Sources:
The samples were prepared with different proportions of vinyl ester and polyurethane to form interpenetrating polymer networks (IPN).
3：List of Experimental Equipment and Materials:
Universal testing machine, vacuum bag shaping equipment, heating coil, water bath, and gas thermometer were used.
4：Experimental Procedures and Operational Workflow:
The Heat Distortion Temperature was determined by the test procedure outlined in ASTM D648. The test specimen was loaded in three-point bending in the edgewise direction with a specified outer fiber stress and temperature increase rate.
5：The test specimen was loaded in three-point bending in the edgewise direction with a specified outer fiber stress and temperature increase rate.
Data Analysis Methods:
5. Data Analysis Methods: The temperature and deflection of each specimen were noted and tabulated for comparison.
