Abstract: We reduce core crush in honeycomb sandwich structure by using a peripheral tiedown ply, generally in combination with a scrim-reinforced barrier film, between the composite laminate and the core along the panel chamfer to prevent slipping of the barrier film and outer laminates relative to the core during curing. We produce superior panels with lighter weights, improved mechanical properties, and more predictable structural performance.
Abstract: A method of making a honeycomb structure includes the step of intermittently slitting a sheet of material such that longitudinal slits are aligned in alternating staggered rows. Each staggered row has a lateral centerline spaced substantially uniformly from adjacent row centerlines. The longitudinal slits in each staggered row have substantially uniform lateral spaces between each slit. Another step is applying continuous stripes of adhesive laterally across a top side and a bottom side of the sheet such that each stripe is spaced apart longitudinally and centered on a row of slits. The stripes alternate between the top side and the bottom side. Still another step includes pleating the sheet such that pleats run longitudinally. Each pleat has a top fold and a bottom fold aligned with a longitudinal slit. Yet another step involves gathering the pleats together in a closed stack and compressing the stack to cause the stripes of adhesive to bond the pleats together at adhesive contact points.
Abstract: Disclosed are improved components for a base rail system for the protection of fixtures such as display shelves, booths, and grocery store refrigeration cabinets. A protruding rotatable corner member rotatably engages objects that collide with the corner, reducing abrasion of the corner and of the object. In addition, the rotatable corner member redirects objects so as to reduce collision forces on the fixture protection system. Socket adapters closely receive a segmented, spheroidal rotatable member and rotatably couple the member to base rail protection members. A base rail protection member includes a single piece arcuate resilient sheath disposed over an arcuate channel member so as to form a cushioning gap therebetween for absorbing and dispersing collision forces. The arcuate sheath includes retaining grooves disposed along the length thereof for engaging tabs disposed along the arcuate channel member.
