Composite materials use in a various industries for example aerospace, car, yacht, etc due to high specific strength, specific modulus and damping characteristic.
Composite materials need to ensure structural reliability that occur defect in manufacturing and using. So non-destructive damage monitoring for composite materials is very important to enhance their structural reliability and many techniques such as ultrasonic, electric, tapping, optical fiber and acoustic-emission methods have been studied.
But there has some disadvantages, such as limited to conductive materials and must use special sensors. The thesis is basic research of develop for non-destructive damage monitoring system such as glass fiber reinforced polymer composite.
The main purpose is development for prediction equation piezoelectric property to develop self sensor type non-destructive damage monitoring system using piezoelectric characteristic.
However, Glass fiber reinforced polymer composite relatively has too low piezoelectric constant compared with general piezoelectric materials.
So, I study on improvement method for piezoelectric property of polymer materials.
There are some techniques such as adding piezoelectric nano-particles and polarization method. In this study, polarization method was used. I measured about composite material design variables according to fiber and matrix types, fiber volume fraction and fiber orientation using piezoelectric characteristics of polymer material.
Finally, I developed based on experimental data about prediction equation for piezoelectric property of composite materials.
