The present invention provides a crosslinked molded article having a lower compression set; and a method for producing a crosslinked molded article by injection molding, the method enabling shortening of one cycle in injection molding, the method being suitable for obtaining a crosslinked molded article having a lower compression set. The present invention relates to a method for producing a crosslinked molded article, comprising melt-kneading a polymer composition containing a polymer having a terminal double bond, a hydrosilyl group-containing compound (Y) having at least two hydrosilyl groups per molecule, a platinum-based catalyst (Z) for hydrosilicon crosslinking, and a reaction inhibitor (D), subjecting the polymer composition to injection molding in a mold, performing primary crosslinking in the mold, removing the primary-crosslinked molded article from the mold, and then performing secondary crosslinking in a heat medium.

A method of making a flexible magnetized sheet is provided. The method may comprise the steps of (1) using cold extrusion to produce a highly viscous fluid magnetizable sheet, (2) passing the sheet through a magnetic field to create an uncured magnetized sheet, and (3) curing the sheet with electron beam curing. The fluid mixture may comprise magnetizable particles with a random charge orientation and an acrylic resin. The components of the mixture are cool when passed through an extrusion die. The extruded fluid sheet allows for the sheet to be magnetized and then, instead of curing by cooling, cured by the bombardment of electrons via an electron beam (EB) generator. The method can eliminate the heat of extrusion and can allow for more freedom of orientation because the sheet does not cure until it reaches the electron beam curing station.

Process for producing a composite material comprising depositing a prepreg containing a radiation initiated curing agent onto a mould using automated apparatus and applying heat and second source radiation to at least partially cure the prepreg at least simultaneously with the deposition of the prepreg. Also epoxy resin formulations of a mixture of a liquid epoxy resin and a solid or semi-solid epoxy resin containing a photoinitiator are used as the matrix in prepregs which are cured or partially cured by radiation to avoid the need for thermal cure in an oven. The formulation is particularly useful in the production of wind turbine blades especially in an automated process. Additionally an automated tape laying apparatus comprising compaction device, a heat source and a second radiation source.
