The past few years have seen several attempts to make laminate composites consist of piezoelectric and magnetostrictive layers to achieve Magnetoelectric (ME) coefficients higher enough for real applications. However, all the efforts are limited to composites with the 2-2 and 3-0 connectivity. In general, the ME field coefficient is much higher in laminate structure with the 2-2 connectivity. In this article, we propose a new type of ferro electromagnetic (FEM) composite with the 3-1 connectivity, that is, the piezoelectric fibers preferentially aligned and uniformly distributed in a magnetostrictive matrix. The ME properties of this type of composite are theoretically studied and compared to that of the 2-2 laminate composite. Our theoretical calculation shows that the 3-1 composite has higher ME field coefficient than the 2-2 one. The advantages and disadvantages of the composites with the 2-2 and 3-1 connectivity are discussed.
