A system including two pre-fixed substrates, wherein a first substrate and a second substrate. Each of the substrates has an opening in an overlap region, and an adhesive is arranged between the overlap regions, wherein the adhesive connects the two substrates together and is arranged at least partly in the openings. The adhesive is locally cured in the region of the openings. A cured sub-region of the adhesive extends from the first opening into the second opening, and a second sub-region of the adhesive is not cured.

A method for producing a sheet molding compound including impregnating a resin composition into carbon fibers. The method is characterized in that the bulkiness H.sub.o of the carbon fibers before an impregnation step is 3 mm or more, the compression ratio R.sub.c (H.sub.c/H.sub.o) of the carbon fibers in the impregnation step is less than 1, the thickness of the sheet molding compound is 10 mm or less, and the content Wc of the carbon fibers is 40% by mass or more. The method for producing a sheet molding compound can produce a sheet molding compound having the excellent impregnation property into carbon fibers and thus can be preferably used for exteriors, structures, and the like of an automotive member, a railroad vehicle member, an aerospace vehicle member, a ship member, a housing equipment member, a sport member, a light vehicle member, a civil engineering and construction member, an OA equipment.

The purpose of the present invention is to provide a sandwich structure that has both excellent heat dissipation properties and excellent mechanical properties. In order to achieve this purpose, the sandwich structure of the present invention has the following structure. The sandwich structure includes a core member (I), and a fiber reinforced member (II) disposed on both sides of the core member (I), wherein the core member (I) includes a sheet-shaped heat conductive member (III) having an in-plane thermal conductivity of 300 W/m.K or more.

A composite prepreg and a fiber-reinforced plastic molded body are described that are excellent in secondary weldability with another member and exhibit excellent handleability and reinforcing characteristics, where the composite prepreg in which reinforcing fibers are impregnated with a thermoplastic resin and a thermosetting resin, and a thermoplastic resin layer and a thermosetting resin layer that form an interface and joined to each other are formed, wherein the thermoplastic resin layer is present on at least one surface of the composite prepreg, and the thermoplastic resin layer contains continuous reinforcing fibers.

Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.
