摘要:
Damping skin for protecting composite parts which comprises a composite material (2) comprising at least two superposed layers (3, 5), namely a first layer (3) formed from the juxtaposition of hollow spheres (4), which is intended to be applied and fixed, either directly or indirectly, to the surface (10) of the part (1) to be protected and a second layer (5) covering the first (3) and formed from a wall made of a material having plastic deformation properties.
摘要:
A box-shaped automotive member includes a box-like body (2) for containing various parts, and this box-like body is formed of a hollow-grains-dispersed composite material having hollow grains contained in a metallic matrix. The content of the hollow grains is 50 to 70%, and the hollow grains are made of a material selected from a mullite material, an alumina material, a carbon material and a SiO 2 material. Particularly when the box-like body is applied to a battery box (1) which can receive a battery or a junction box, this is effective for enhancing the fuel consumption.
摘要:
An inorganic constructional board used for a wall foundation member and the like, which comprises: a middle layer portion (1a) including inorganic foam as its main body and suitable amounts of a fiber material and a bonding agent added to the foam; and outer layer portions (1b) provided on the front and rear surfaces of the middle layer portion (1a), including mineral fibers and an inorganic powder material as its main body and a bonding agent added to them. The specific gravity of the middle layer portion (1a) is made to be 0.4 or therebelow and the specific gravity of the outer layer portion (1b) is made to be 0.7 or thereabove, so that the inorganic constructional board is made lighter than a gypsum board and can provide performance equal to or higher than that of the gypsum board. This inorganic constructional board (1) is manufactured in such a way that a wet inorganic mat as being the under-layer (1b) of the aforesaid construction is made, the middle layer portion (1a) of the aforesaid construction is formed on the under-layer (1b) by a dry method or a wet method, the wet inorganic mat as being the upper layer portion (1b) of the aforesaid construction is superposed on the middle layer portion (1a), and these laminated components are pressed to be integrated, heated and dried.
摘要:
A mixture of vinyl plastisol, suspension grade resin and expanded perlite is prepared in a manner such that the particles of perlite are not significantly damaged. The mixture is placed on a substrate and fused, thereby producing a foam-like material which is usable as a decorative covering. Alternatively, the mixture can be cast on a release surface and allowed to stand until the majority of the perlite particles have migrated to the top surface, thus leaving a layer of material containing substantially no perlite along the lower surface which interfaces with the release surface. Upon fusing this stratified mixture and separating the release surface, the fused material is inverted. The layer of material which contains substantially no perlite becomes the protective surface and the remaining portion of the fused material, which is foam-like in nature, becomes the resilient support. Such syntactic foams may be used as replacements or substitutes for mechanically frothed or chemically blown foams.
摘要:
A flexible and substantially crack resistant intumescent, non-intumescent, or hybrid mounting mat material for use in mounting fragile structures includes at least one intumescent, non-intumescent or hybrid layer containing inorganic fibers and reinforcing layer applied to the layer. Also provided is an exhaust gas treatment device including a housing, a fragile catalyst support structure mounted within the housing, and the crack resistant mounting mat disposed in a gap between the housing and the fragile catalyst support structure. Also disclosed are methods of making a mounting mat for an exhaust gas treatment device and for making an exhaust gas treatment device incorporating the mounting mat.

摘要:
The combination of ingredients, especially for use in the formulation of a one or two-pack retroreflective ink, comprising retroreflective elements, microbeads additional to said retroreflective elements and/or constituting said retroreflective elements at least in part, binder chemicals for attaching the retroreflective elements and microbeads to a substrate to which the ink is to be applied, and a coupling agent for coupling the microbeads and cross-linking the binder chemicals, the coupling agent being unreactive until the printing process is carried out.
