A structural panel and method of fabricating and manufacturing same comprises a top panel and a bottom panel separated by and attached to at least one, but preferably a plurality, of structural composite preforms which may be fabricated by a continuous manufacturing process and may be saturated by resin using a continuous wetting process. The composite preforms may take any cross sectional shape but are preferably trapezoidal. The top and bottom panels may be fabricated from a plurality of layers of woven fabric layers and non-woven fabric layers which are saturated with a resin that is subsequently cured using cure processes known in the art. The composite structural panel of the invention is usable as a flat structural member for use as bridge decking, ramps, trestles, and any application requiring a structural panel.

A male touch fastener strip includes an elongated base and a field of male fastener elements each having a stem extending from a broad face of the base and a head for engaging fibers. The fastener element stems and broad face of the base together form a unitary mass of resin, such as a resin containing a magnetically attractable substance. Wings extend from respective longitudinal edges of the base and define discrete corrugations extending in a series along the fastener strip and forming corresponding undulations in the rear face of the strip along its longitudinal edges. The corrugated wings can also support a foam gasket.

The present invention relates to processes for producing sandwich elements, where the sandwich elements comprise a rigid polyurethane foam as core foam surrounded entirely or to some extent by a plastics resin comprising reinforcing-agent layers, by producing the rigid polyurethane foam on the reinforcing-agent layers and then saturating the reinforcing-agent layers in a liquid resin and hardening the resin. The present invention further relates to sandwich elements that can be produced by a process of the invention, and also to the use of these sandwich elements as wind-turbine blade, aircraft wing, wind-turbine nacelle, boat-hull, or housing for vehicles.

Method of using a viscous printing ink for the protection of a notch formed in a skin which is intended for a part that is produced using a method including: producing a skin (1) having a notch (2) on the inner face thereof, covering the notch (2) with a protective element, and forming a foam (3) which is in contact with the inner face of the skin. According to the invention, during the notch-covering step, an ink having a viscosity that is at least equal to 0.6 St is applied to the notch (2) via printing and, subsequently, the ink is hardened such as to form a layer (4) that provides a bridge over the notch (2) without extending to the base thereof. The invention is suitable for motor vehicle instrument panels.

Various embodiments of a mold assembly system include a mold defining at least one trench along a surface of the mold and two or more hook fastener elements disposed on the surface of the trench in an end-to-end relationship. Each hook fastener elements includes: (1) an elongated base, (2) a plurality of hooks extending upwardly from an upper surface of the base, and (3) a magnetic material disposed within the base. The hook fastener elements are unattached to each other and are separately disposed within the trench, and the magnetic portion of the trench is configured to attract the hook fastener elements toward the magnetic portion and hold the hook fastener elements adjacent thereto in an end-to-end relationship substantially along the length of the trench. In one embodiment, the hook fastener elements are substantially the same length and are usable in straight trenches, curved trenches, or trenches having various lengths.

Various embodiments include a male surface fastener member configured for being molded onto a surface of a foaming resin mold body. The male surface fastener member includes a plurality of male surface fastener strips connected with each other in an end-to-end relationship via a connecting portion that is integrally formed with at least the end portions of each male surface fastener strips. Each male surface fastener strip includes a base material having a first surface from which a plurality of engaging elements extend upwardly and first and second substantially lateral resin intrusion prevention walls that upwardly from the first surface along a width direction of the base material between the first and second longitudinal resin intrusion prevention walls. Each of the lateral resin intrusion prevention walls comprises a plurality of engaging elements that are arranged in series in a width direction of the first surface.

A fastening assembly and a cushion having the same are provided. The fastening assembly includes a first band, a second band, a third band, and a magnetic layer. The first band has a first surface protrudingly provided with plural hooks, and a second surface. The second band has a third surface and a fourth surface, with the third surface bonded to the second surface of the first band. The second band is wider than the first band and forms a pair of wings protruding beyond longitudinal edges of the first band, respectively. The third band, narrower than the second band, has a fifth surface and a sixth surface, with the fifth surface bonded to a central portion of the fourth surface of the second band. The magnetic layer is located on the third surface or the fourth surface of the wings of the second band and comprises a magnetic material.

Touch fasteners for use as mold inserts in molding seat foam buns include a strip-form base a magnetically attractable material disposed on the strip-form base; and film selvedges biased to depend downward from the strip-form base toward the fastening side, such that they will be deflected away from the fastening side as the fastener is pressed into an associated trench.
摘要:
Touch fasteners for use as mold inserts in molding seat foam buns include a sheet-form base a magnetically attractable material disposed on the upper face of the sheet-form base, and a film cover covering the magnetically attractable material wherein maximum slope angle of the film cover, is less than about 75° as measured from the upper surface of the sheet form base to the outside surface of the cover. The magnetically attractable material is a strand of frangible composite constructed to be readily segmented with the seat foam bun during recycling.
