研究目的
Investigating the effects of different PZT volume fractions and carbon fiber reinforcement on the dielectric, piezoelectric, mechanical, and microstructure properties of PZT/PVDF composites.
研究成果
The study concluded that an appropriate amount of carbon fiber can significantly improve the mechanical and electrical properties of PZT/PVDF composites. The optimal proportion was found to be 50%PZT/50%PVDF with 0.25% carbon fiber content, which showed significant improvements in d33, bending strength, and tensile strength.
研究不足
The study focuses on the effects of PZT volume fractions and carbon fiber content on the composites' properties but does not explore the long-term durability or environmental impact of these composites.
