An enhanced thermal insulation vacuum panel is provided. The enhanced panel comprises a thermal insulation vacuum panel formed in part by an envelope having an outer periphery and framing structure secured to at least a portion of the outer periphery of the panel.

Enhanced insulation panel

An insulation panel has a modular thermal insulation vacuum panel and a frame structure secured to the outer periphery. An outer edge portion of the panel and frame assembly is provided with a profile and is adapted to mate with an edge of an adjacent thermal insulation panel and frame assembly. Profile members may be inserted between insulation panels to form a wall assembly. Insulation panels have a central portion of reduced thickness so as to allow for application of conduits. The modular thermal insulation vacuum panel has insulating media enclosed within spaced panel segments.

Modular insulation panels and insulated structures

Improved insulating modular panels are manufactured to incorporate into each insulating modular panel at least one vacuum insulation panel. Vacuum insulation panels are conveyed seriatim toward a pultrusion die which ultimately produces the insulating modular panels as a continuous block. Joint spacings or gaps between adjacent vacuum insulation panels and sides of the vacuum panels are filled with foam or preformed filler material to form a substantially continuous inner core which has substantially continuous side edges. Reinforcement material is applied to the inner core. The reinforcement material can be impregnated with resin prior to its application to the inner core or resin may be injected into the pultrusion die. In either event, a continuous elongated block of insulating modular panels emerges from the pultrusion die. The continuous elongated block is severed at joint spacings or gaps between adjacent vacuum insulation panels to form insulating modular panels of desired sizes from the block. Preferably, the sides of the insulating modular panels are formed to define intermating members which engage one another to facilitate construction using the insulating modular panels.

A molded composite product includes a resinous core layer containing reinforcement fibers, and a resinous surface layer which is substantially free of reinforcement fibers, where the resinous surface layer includes a nonresinous additive at a concentration, measured as a weight percentage of the resinous material in the surface layer, which is higher than the concentration of the additive in the resinous core layer, measured as a weight percentage of the resinous material in the core layer.

The present invention provides a fiberglass composite which possesses outstanding armor properties. This ballistic resistant composite material employs high strength magnesia aluminosilicate glass fibers and phenol formaldehyde condensation product as the matrix resin. The composite is produced from sheet molding compound using little or no solvent.

Ballistic materials

Panels are disclosed which are suitable for joiner, non-structural bulkheads. The panels are a laminate having a central portion of gypsum or a magnesium oxy-chloride cement which may or may not be glass fiber reinforced and externally exposed fire-resistant skins directly bonded to opposite sides of the central or core material. These skins are formed of a solid phenol-formaldehyde glass resin composite such as for example a prepreg formed from a woven glass roving of a high strength, high melting point glass and a cured phenol-aldehyde resin.

Fire-resistant panel system

A process for forming flat plate ballistic resistant composites which includes impregnating a low-alkali magnesia-aluminum-silicate glass fiber woven roving with an impregnating composition. The impregnating composition includes a resin solution of a polyester resin in a polymerizable monomeric solvent a free radical catalyst and optionally, a thickening agent and further optionally a flame retardant material. The impregnated woven roving is cured in a molding unit at a temperature of about 225.degree.-255.degree. F. for a sufficient period of time and at a sufficient pressure to allow the impregnated woven roving to substantially conform to the mold unit. The temperature and pressure used are sufficient to maintain the exothermic temperature at about 300.degree. F. or below and to catalytically crosslink the polyester resin and monomeric solvent.

The present invention relates to the method of producing an interface that intimately bonds to common molding compounds; even though they contain mold release agents. The method utilizes a material at the surface of the molded part that bonds to the surface of the part but not to the steel mold. This not only permits the molding of an article using common industry techniques but more importantly the subsequent postmolding of a pigmented or protective resinous coating on one surface of a molded article. The method eliminates the need for special surface preparation such as sand blasting, scuff sanding, etc., to facilitate bonding of a secondary coating.

Method of obtaining interface adhesion and articles produced thereby

Disclosed is a method of bonding two layers of thermosetting plastic. A thin sheet of thermoplastic material is interpositioned between two layers of thermosetting plastic and the combination is subjected to temperatures sufficient to cause the thermosetting plastic layers to bond and cure. The thermosetting plastic contains mold release agents which are absorbable by the thermoplastic sheet, and crosslinking monomers in which the thermoplastic sheet is dissolvable at molding temperatures.

Method of obtaining interface adhesion between thermosetting layers

This invention proposes a method for eliminating 'sink' in molded glass fiber reinforced panels for automotive and other uses. Such panels are normally formed with integrally molded reinforcement shapes (ribs) and fastening locations (bosses), and a slight depression or 'sink' occurs in the exposed panel surface over the location of the ribs and bosses. The present invention proposes the elimination of this sink by utilizing innovative material and design techniques that compliment one another. The material approach makes use of dual reinforcements; normal chopped glass fibers reinforcement (1 inch or less in length) in combination with a long fiber reinforcement (2 inches or more in length) and preferably a continuous fiber reinforcement. The long fiber reinforcement is placed such that it is oriented in the panel to closely underlie the exposed panel surface. The short chopped fiber, but not the continuous fiber of the composite reinforcement, enters the rib to reinforce the same, while the continuous glass fibers bridge across the rib. The major design consideration is that the juncture points where the rib or boss meets the basic laminate have a sharp or minimum lead-in radius. This lead-in radius should be no greater than .005 - .01 inch, as contrasted with previously recommended 'generous' lead-in radii of from 1/8 to 1/4 inch. This geometry tends to minimize segregation of material flowing into the ribs and bosses as well as minimize the cross-sectional area of this juncture. The material and design approaches may be used separately to minimize 'sink' and, the visual distortion caused by that differential thermal shrinkage resulting from material non-uniformity and glass orientation as the rib fills and the resin exothermically cures.
