摘要： A method for forming microcellular foams that causes the material to expand uniaxially during the foaming process, and a method for forming objects from the foam. Liquid crystal polymers or polymers having a planar crystalline structure are saturated with a fluid, normally a gas such as carbon dioxide. The ambient conditions are changed such that the fluid is in a supersaturated state, and the material is brought to near its glass transition temperature to induce the formation of nonspherical elongated gas-filled cells. A process for making objects, such as transducer diaphragms, from microcellular foams includes the step of forming the objects prior to the foaming process.

摘要： The present invention relates to a process for producing a molding made from blowing agent-containing foam comprising at least one fiber (F), wherein the at least one fiber (F) is partially introduced into the blowing agent-containing foam. The two ends of the respective fiber (F) that are not surrounded by the blowing agent-containing foam thus project from one side of the corresponding molding. The present invention also provides the molding as such. The present invention further provides a panel comprising at least one such molding, produced by the process according to the invention, and at least one further layer (S1). The present invention also provides for the production of the panels of the invention and for the use thereof, for example as a rotor blade in wind turbines.

摘要： A method of manufacturing a foam body having an anisotropic cell structure, the method including the steps of: expanding a polymer at an elevated temperature to form an initial foam body; and cooling the initial foam body under a negative pressure. There is also provided a method of manufacturing a foam body having an anisotropic cell structure, the method including the steps of: (a) in a first expansion step, expanding a foamable polymer composition substantially isotropically to form an initial foam body having an isotropic cell structure; and (b) in a second expansion step, expanding the initial foam body anisotropically in a selected direction under a negative pressure which applies an expanding force in the selected direction to provide a final foam body having an anisotropic cell structure. Apparatus for the methods are also disclosed.
