  • Patent number: 9888570
    Abstract: An enhanced prepreg for printed circuit board (PCB) laminates includes a substrate and a resin applied to the substrate. The resin includes a curable polymer and a polymerization initiator polymer having a backbone with a free radical initiator forming segment that breaks apart upon being subjected to heat to generate a plurality of non-volatile initiating species. This resin composition eliminates possible volatile loss of the free radical initiator during all processing steps in the preparation of PCB laminates. The resin may additionally include a cross-linking agent, flame retardant and viscosity modifiers. In one embodiment, a sheet of woven glass fibers is impregnated with the resin and subsequently dried or cured. The glass cloth substrate may include a silane coupling agent to couple the resin to the substrate. In another embodiment, resin coated copper (RCC) is prepared by applying the resin to copper and subsequently curing the resin.

  • Patent number: 7987645
    Abstract: A noise-reducing substrate for use in a flooring system which ha a subfloor and a floating floor upper layer. The substrate comprises a series of edge butted panels, each having a bottom surface, a top surface and side surfaces. A profile in the bottom surface of the substrate changes the substrate's effective stiffness improving the noise isolation of the substrate compared to the stiffness and noise isolation of the panel without the profile. Additionally, the profile reduces the weight of the panel, thereby reducing manufacturing and installation costs. Material hardness and profile flatness of the upper surface provide the strength and texture required to allow for installation of the floating floor layer without the need for an additional rigid backing material. Such a system greatly improves the impact noise reduction on floor/ceiling systems while keeping the installation cost low and adding little to the total system thickness.

    Abstract: A three-dimensional support structure is provided and includes a single sheet of material that is folded into a repeating pattern of cells. Each of the cells is formed by first and second spaced-apart endwalls and first and second sloped sidewalls spanning between the endwalls. Each endwall comprises two plies of material while each sidewall comprises a single ply of material. The first and second sidewalls are adjoined at a folded edge. The cells are aligned such that the first endwall of one cell from the repeating pattern abuts the second endwall of an adjacent cell of the repeating pattern to form a four-ply wall of the material. A first liner may be attached to a first side of the folded material and a second liner may be attached to a second side of the folded material.

    Abstract: An embossed sheet is composed of at least a first and a second ply of creped tissue having a basis weight between 12 and 30 g/m2 according to which the first ply has a first embossed pattern composed of a series of first aligned protrusions of frustoconical overall shape, the tops of which are oriented towards the inside of the sheet, and the second ply has a first and a second series of protrusions, the tops of which are oriented towards the inside of the sheet, the second series having a height greater than that of the first series of protrusions. The protrusions of the first ply and the highest protrusions of the second ply are nested inside one another, and the lowest protrusions of the second ply are arranged between the protrusions of the first ply so as to create empty spaces between the two plies and promote a rapid absorption of liquid.

  • Patent number: 7452589
    Abstract: Present invention relates to a process of forming a multi-layer pad of a non-woven fiber batt and a foam layer having conforming convoluted surfaces and to a multi-layer pad incorporating a non-woven fiber batt and foam layer. The process of forming a non-woven batt layer and a foam layer having conforming convoluted surfaces comprises transporting each layer along its longitudinal dimension while compressing each layer along its lateral dimension. Concomitantly with compression, each layer is cut transversely along its lateral dimension to separate each layer into an upper segment and a lower segment and to provide conforming convoluted surfaces on the segments of each layer, the convoluted surfaces comprised of upstanding projections and depressions.

  • Publication number: 20080081156
    Abstract: The present invention relates to sheet-like materials suitable for use in the containment and protection of various items, as well as the preservation of perishable materials such as food items. More particularly, the present invention provides an improved storage wrap material comprising a sheet of material having a first side and a second side. The first side comprises an active side exhibiting an adhesion peel force after activation by a user which is greater than an adhesion peel force exhibited prior to activation by a user. The storage wrap material may be activated by different approaches, but in a preferred embodiment the active side is activatible by an externally applied force exerted upon the sheet of material. The force may be an externally applied compressive force exerted in a direction substantially normal to the sheet of material.

    Abstract: A composite panel waffle stiffener has fabric plies pre-cut to a selected pattern and laid on a tool having a waffle configuration. The plies overlap each other to maintain continuity of the structure. The resulting waffle stiffener is then bonded to a panel requiring stiffening. The stiffener is flexible and may be bonded to curved panels. Holes in the stiffener allow access to the volume between the stiffener and the panel for minimizing volume loss within, for example, a wing structure containing fuel and for ventilating air or moisture trapped in the volume.

  • Patent number: 6846574
    Abstract: A device having an improved thermal barrier coating (46) and a process for manufacturing the same. A support structure (28) for retaining a ceramic insulating material (46) on a substrate (16) is formed by the deposition of a support structure material through a patterned masking material (14). The support structure can define cells into which the ceramic insulating material is deposited following removal of the masking material. The masking material may be patterned by known photolithographic techniques (22,24) or by laser etching (48). The support structure (28) may be a composite metal-ceramic material having either discreet layers (30,34) or a graded composition and may be deposited by an electro-desposition process followed by a heat treatment to form a solid state diffusion bond with the substrate.

    Abstract: A protective packaging sheet which is particularly suitable for packaging heavy loads such as coils of sheet steel. The packaging sheet is formed from a plastics sheet material having inherently relatively low compressions strength and resistance to impact forces and bending. These mechanical properties are vastly improved in the embossed packaging sheet. At least one of the surfaces of the sheet material is provided with shaped protuberances juxtaposed with adjacent shaped protuberances to provide a gap around each shaped protuberance. The shaped protuberances are arranged in such a way that all straight lines projected onto the surface cut through the shaped protuberances in addition to the gaps.
