Method for making improved composite materials
A strip of curable prepreg comprising unidirectional fibers aligned with the length of the strip, the fibers being at least partially impregnated with curable thermosetting resin and comprising a flexible polymeric sheet on an outer face of the strip, wherein the strip has a substantially rectangular cross-section defining a width and a thickness of the strip.
Floor panel
A floor panel may include a substrate having a top side and a bottom side. A top layer may be provided on the substrate. The top layer may consist of a printed thermoplastic film and a thermoplastic transparent or translucent layer provided on the printed thermoplastic film. The top layer may be directly applied to the substrate using a glue layer available between the printed thermoplastic film and the top side of the substrate. The substrate may be an extruded synthetic material board including a filler selected from the group consisting of chalk, wood and sand. The substrate at least at two opposite edges may include coupling means provided in the extruded synthetic material board. The floor panel may have a thickness of 5 to 10 millimeters.

Apparatus and a method for bonding and insulating Nd—Fe—B permanent magnets
A method for bonding a plurality of Nd—Fe—B permanent magnets includes a step of curing the layer of insulating adhesive at an initial temperature of between 20° C. and 250° C. and between 0.1 hr and 24 hr prior to the step of sandwiching. A predetermined clamping pressure of between 0.1 MPa and 10 MPa is then applied to the Nd—Fe—B permanent magnets. The stacked Nd—Fe—B permanent magnet is cured at a predetermined temperature of between 150° C. and 350° C. and between 0.1 hr and 12 hr. A clamping tool apparatus includes at least one of three intermediate guides disposed on the lower plate, in the chamber, spaced from the magnet positioning members, and extends to a proximal end defining a second predetermined distance with the second predetermined distance being less than the first predetermined distance of the magnet positioning members. The upper plate defines a plurality of apertures for receiving the magnet positioning members and the intermediate guides.
