摘要:
A passive fire protection system for the protection of vertical walls (28) against flames and heat in a severe total environment type fire, the system including a multi-layered, flexible material containing at least one layer of intumescent material (17). This multi-layered material is configured such that it provides a containment system for the carbonaceous foam resulting from the expansion of the intumescent (17). The system further includes an installation process whereby the attachment of this multi-layered material to vertical surfaces is protected from the extreme heat of a fire.
摘要:
A material to reduce the effects of trauma received from the impact of a projectile. One embodiment is a needle-punched, non-woven material including at least one type of ballistic fibers selected and oriented to provide a cushioning effect and maintain a high compressive restitution constant. A percentage of the fibers are oriented with at least their ends lying approximately perpendicular to the fabric plane and/or oriented to lie in a waveform generally along or parallel to the fabric plane. This enables the ends of the fibers lying perpendicular to the fabric plane to cushion the impact from the projectile by dissipating energy through compressional resistance, and the fibers along the fabric plane to reduce energy through dispersal along fiber lines, thereby reducing the trauma resulting from an impact.

There is described a multi-layer material comprising at least one layer of a metal foil, for example of stainless steel, and at least one layer of a heat-penetration-retarding material, for example a carbo-flex cloth. The material comprises optionally additional insulation material and a protective cloth as a jacket or case which envelops vital installations such as pipe members, flanges and the like for reducing heat penetration to the installation. The material is furthermore explosion proof and exhibits good sound-absorbing ability.

A wood structural member of the present invention, such as a laminated wood beam, a wood I-beam, or a truss, includes synthetic fiber reinforcing panels (22). The reinforcing panels (22) include multiple synthetic fibers (24) that are arranged parallel to one another and aligned with the longitudinal direction of the panel, and accordingly the wood structure. The fibers (24) are maintained in position by a resin encasement (26). Preferably, the surface of the reinforcing panel (22) is treated so that the reinforcing panel may be adhered to the structural member with non-epoxy adhesives, such as resorcinol, commonly used in the laminated beam industry.

摘要:
A bituminous roofing membrane (10), and method of manufacture, is disclosed having a reinforcing mat (16) sandwiched between top (12) and bottom (14) layers of a tacky polymer modified bitumen. The leading edge portion (20) of the top layer (12) is provided with a layer of roofing granules (24). A track of adhesive (26) is provided on the roofing granules (24). The trailing edge portion (22) of the top layer (12) is provided with a layer of non-slip plastic film (28). A release sheet (18) is applied to the bottom layer (14) of the membrane (10) to prevent engagement of the top (12) and bottom (14) layers with one another when the membrane is rolled for storage or shipment. In use, upon removal of the release sheet (18), the membrane (10) is secured to the roof with the leading edge portion (20) constituting a starter strip for receiving thereon the first row of roofing shingles (42), and the trailing edge portion (22) constituting an underlayment for receiving thereon successive rows of roofing shingles (42).
摘要:
A fiber-reinforced cementitious sheet (94) is formed by first co-mixing in an air current duct (74) reinforcing fibers such as glass fibers, and cementitious mineral materials in finely particulate form such as calcium sulfate hemihydrate, both in substantially dry form, depositing the mixture on a moving foraminous surface (79) by means of the air current to form a sheet (87), applying water as by spraying (92) in at least an amount which is stoichiometrically sufficient to hydrate the calcium sulfate hemihydrate to the dihydrate form and to provide the necessary degree of plasticity to the mixture, densifying the sheet (87) by compression rolls (93), and setting and drying the sheet (94). A pair of sheets (94) may be utilized as face sheets and, prior to setting, combined with core (98) formed of for example a calcium sulfate hemihydrate slurry, and the sheets and core then set and dried to form a paper-free gypsum board (105) having excellent strength, surface hardness, and fire-resistant properties.
摘要:
According to one embodiment, a polyisocyanurate foam board is described. The foam board includes a polyisocyanurate core that is produced from: an isocyanate, a polyol, and a phosphorous containing non-halogenated fire retardant. The foam board also includes a facer material that is applied to at least one surface of the polyisocyanurate core. The polyisocyanurate core has an isocyanate index greater than about 200 and is able to forms a sufficiently stable char when exposed to flame conditions to enable the polyisocyanurate core to pass the ASTM E-84 test. The foam board has an initial R-value of at least 6.40 and exhibits an ASTM E1354-11 b test performance that is equivalent with or better than a similar foam board having a halogenated fire retardant, such as tris(2-chloroisopropyl)phosphate (TCPP).
