Investigation into the Fiber Orientation Effect on the Formability of GLARE Materials in the Stamp Forming Process

Abstract: Glass-reinforced aluminum laminate (GLARE) is a new class of fiber metal laminates (FMLs) which has the advantages such as high tensile strength, outstanding fatigue, impact resistance, and excellent corrosion properties. GLARE has been extensively applied in advanced aerospace and automobile industries. However, the deformation behavior of the glass fiber during forming must be studied to the benefits of the good-quality part we form. In this research, we focus on the effect of fiber layer orientation on the GLARE laminate formability in stamp forming process. Experimental and numerical analysis of stamping a hemisphere part in different fiber orientation is investigated. The results indicate that unidirectional and multi-directional fiber in the middle layer make a significant effect on the thinning and also surface forming quality of the three layer sheet. Furthermore, the stress-strain distribution of the aluminum alloy and the unique anisotropic property of the fiber layer exhibit that fiber layer orientation can also affect the forming depths as well as the fracture modes of the laminate. According to the obtained results, it is revealed that multi-directional fiber layers are a good alternative compared to the unidirectional fibers especially when a better formability is the purpose.

Ceramic microstructures and potential applications

Abstract: The developed process of tape casting with subsequent stamping is a promising way to make three-dimensional ceramic microstructures. Examples of different ceramic materials illustrate, that a good quality of the moulding with high form fit can be attained after optimisation of the slurry and the stamping process. The sintered microstructures are characterised by lateral dimensions in the micron range and high aspect ratios. The unique properties of ceramic materials in combination with this new process can be used to produce microstructured ultrasonic transducers or micro heat exchangers/reactors.

Method of manufacturing formed component having very high mechanical property by standing from covered rolled steel sheet, in particular, covered hot-rolled steel strip

Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a formed component having a very high mechanical properties by stamping a rolled steel sheet covered by metal or a metal alloy for reliably protecting the surface of the steel sheet and steel inside thereof, in particular, a hot rolled steel strip. SOLUTION: This manufacturing method comprises a step of cutting the steel sheet to obtain a steel sheet blank, a step of forming the component by stamping the steel sheet blank, a step of covering the surface of the steel sheet by an intermetallic compound capable of ensuring the protection against the corrosion and the decarburization of steel and ensuring the lubricating function, and a step of cutting and removing an excess portion of the steel sheet necessary for the stamping.
