A system for producing a multiple layer material (49), comprising first and second corrugation rolls (14, 15) for providing a corrugated profile (16) having a plurality of crests (47), wherein the system further comprises first and second press rolls (21, 22) for applying a material sheet (19, 20) to crests (47) of the corrugated profile (16), and a plurality of heating members (28) arranged between the press rolls (21, 22) for welding the material sheet (19, 20) to the crests (47) of the corrugated profile (16) to form the multiple layer material (49). A guiding plate (48) is arranged between the corrugation 10 rolls (14, 15) and the heating members (28). The guiding plate (16) is arranged with a profile engaging side (50) having a plurality of crests (52) corresponding to the crests (47) of the corrugated profile (16). A cooling arrangement is provided for cooling the guiding plate (48). A method for producing the multiple layer material (49) is also disclosed.

Bio-inspired carbon fiber reinforced polymer (CFRP) composite laminates are provided. The CFRP laminates display high out-of-plane strength and ductility due to the incorporation of defects (e.g. areas of delamination) which are purposefully introduced into the laminate layers.

A wrappable protective sleeve for providing protection to at least one elongate member contained therein and methods of construction and use thereof are provided. The sleeve includes a flexible textile wall having opposite inner and outer faces bounded by opposite edges and opposite ends. The opposite edges extend generally parallel to one another between the opposite ends. A pair of adhesive layers is bonded to the inner face, with each of the adhesive layers being spaced from one another. The adhesive layers extend between the opposite ends adjacent the opposite edges. Further, a release paper is releasably adhered to the pair of adhesive layers for subsequent removal and use of the sleeve.

The present disclosure relates to a laminating method and device for a display module, a display module and an electronic device. The laminating method includes steps of: laminating a second panel on a first surface of a first panel, and positioning the second panel relative to the first panel; and coating a bonding adhesive on a side surface of the second panel along an outer circumference of the second panel and curing the bonding adhesive to form a sealing frame adhesive on an outer circumference side of the second panel and the first surface of the first panel, so that the first panel and the second panel are bonded and fixed by the sealing frame adhesive, wherein a gap defined by the sealing frame adhesive, the first panel and the second panel is in a negative pressure state.

A layer composite is a sandwich structure, in which a PUR foam layer is needle-punched with two nonwovens.

A retroreflective article including a binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements include a reflective layer that is a locally-laminated reflective layer that is embedded between the transparent microsphere and the binder layer. At least some of the locally-laminated reflective layers may be localized reflective layers.

This invention relates to a functional textile manufacturing system. This system uses weaving equipment, dyeing and finishing equipment, shaping equipment, evaporation equipment, lamination equipment, roll adhesion equipment and printing equipment for production. Weaving equipment, dyeing and finishing equipment and shaping equipment are used for weaving, dyeing, washing and shaping to process low-cost polyester fibers into shaped fabric. Then, the evaporation equipment is used to evaporate a metal onto a plane release film to form a metal evaporation release film, and the lamination equipment, roll adhesion equipment and printing equipment are used to laminate the shaped fabric and the metal evaporation release film and to adhere a printed layer on the functional thin film. Such a manufacturing system can produce laundry resistant unconventional material antimicrobial protective fabric that features special temperature control, antimicrobial, waterproof, breathable, scratch resistant properties, as well as comfortable feeling.

A pad of dispensable adhesive tape segments is shown and described. The pad includes a protective envelope and a number of tape segments. The tape segments are arrayed such that detachable pull tabs for each are exposed for grasp. The envelope may include a strip folded over onto itself and adhered in place. The envelope is pulled open and may be adhered to an environmental surface. Tape segments have adhesive of weaker adherence than the adhesive of the envelope so that when pulled by a pull tab, each tape segment preferentially releases from the next, but the envelope maintains adherence to the environmental surface. Adhesive lined tabs initially holding the envelope closed may also be used for adherence to the environmental surface. Preferably used for medical tape, the envelope is waterproof to maintain sterility of tape segments.

An apparatus includes a method for providing a Shape Memory Polymer Based Passive Thermal Diode (SMP-PTD) that includes layers and is configured to provide passive heating and cooling of a pipeline. The SMP-PTD includes a polyurethane (PU) layer configured to contact at least an upper portion along a length of a pipe. The SMP-PTD further includes a polyethylene terephthalate (PET) layer configured to surround the PU layer and the length of the pipe. The SMP-PTD further includes a graphene layer configured to surround an upper side of the SMP-PTD and cross layers of the SMP-PTD toward a bottom side of the SMP-PTD to establish contact with the pipe. The SMP-PTD further includes an epoxy shell configured to surround the graphene layer. The SMP-PTD further includes a shape memory polymer (SMP) ring configured to provide vertical displacement and push upward upon lateral displacement from pushing by left and right PET blocks. The SMP-PTD is installed on the pipeline.

A method for manufacturing a sound-absorbing panel with a sandwich structure for reducing noise impact of an aeronautic engine includes providing a first skin of a thermoplastic polymeric material, making a plurality of micro-holes through the first skin by mechanical punching of the first skin, securing the first skin to a central layer by arranging a structural adhesive layer between the first skin and the central layer and/or by a thermal weld between the first skin and the central layer, and securing the central layer to a second skin by arranging a structural adhesive layer between the central layer and the second skin and/or by a thermal weld between the central layer and the second skin.
