Abstract: The hot pressure formability of glass fiber reinforced metal laminates (GLARE) with single curvature is studied. Based on the wall thickness distribution and forming depth of specimens, the influence mechanism and law of temperature and pressure on the hot pressure formability of the thermosetting and thermoplastic resin based GLARE laminates are explored experimentally. The results show that the high temperature would cause the decomposition failure of the two kinds of resins, leading to laminates defects such as delamination and rupture. At high temperature, the fluidity of the molten resin increases, and the extrusion of the upper and lower plates makes the resin flow outward along the radial direction, which reduce the thickness of the center of the specimen. At the same time, the pressure of the blank holder lead to the accumulation of resin, which increases the thickness of the laminates in the rounded corner area. When the temperature is 110～140 ℃, the formability of the thermosetting resin prepreg GLARE is good, and the lowest pressure of the specimen laminate mold is 4 MPa. When the temperature is between 170 ℃ and 200 ℃, the formability of the thermoplastic resin prepreg GLARE is optimal, and the minimum pressure of the specimen laminate mold is 3 MPa.
