Abstract:

X-Cor sandwich composite is a novel structure which is reinforced by inserting Z-pin in the thickness direction, so that this sandwich structure has a high specific strength and specific stiffness. With different Z-pin inserting parameters, the X-Cor sandwich composites are prepared with hot press molding process. The effects of Z-pin inserting angle, inserting density and inserting direction on compression and shear properties are investigated. Results show that the Z-pin inserting parameters have great effects on X-Cor sandwich composites.
