The present invention relates to a heat-insulating structural material, which: firstly, can minimize or prevent a thermal bridge by improving the structure of the connection part of the heat-insulating structural material; secondly, improves insulation performance by arranging a vacuum insulation material inside the core layer of the heat-insulating structural material; and thirdly, increases structural stiffness by forming the core layer from a non-foaming polymer material having excellent structural performance, prevents gas from moving in or out of the vacuum insulation material through the air-tight adhesive structure of the core layer, and can improve fire protection performance so as not to be vulnerable to fire, and thus the present invention is universally applicable to fields requiring insulation ability and structural performance.

Structurally enhanced preformed layers of multiple rigid unidirectional rods are constructed and arranged for use in fabricating load-bearing support structures and reinforcements in a variety of composite components, e.g. wind turbine blades. Individual preform layers include multiple elongate unidirectional strength elements or rods arranged in a single layer along a longitudinal axis of the preform layer. Individual rods include aligned unidirectional structural fibers embedded within a matrix resin such that the rods have a substantially uniform distribution of fibers and high degree of fiber collimation. The relative straightness of the fibers and fiber collimation provide rods and the preform layers with high rigidity and significant compression strength. A plurality of rods are loosely attached, e.g. knitted, together with a coupling that allows for each rod to be axially displaced, e.g. slideable, relative to another rod.

Provided is an interlayer film for laminated glass capable of enhancing the sound insulating property in a low-frequency region while keeping the sound insulating property in a high-frequency region high. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a two or more-layer structure, the interlayer film has one end, and the other end being at an opposite side of the one end, each layer contained in the interlayer film has one end, and the other end being at an opposite side of the one end, the one end of the each layer is located at the one end side of the interlayer film in a direction connecting the one end and the other end of the interlayer film, the other end of the each layer is located at the other end side of the interlayer film in the direction connecting the one end and the other end of the interlayer film, in the interlayer film, a thickness of the other end is larger than a thickness of the one end, and in at least one layer contained in the interlayer film, a thickness at the other end is smaller than a thickness at the one end.

A marine vessel floor mat for attachment to the deck of a boat to provide enhanced cushioning to stand on. In one embodiment, the marine vessel floor mat comprises a cushion layer shaped to fit the dimensions of the bow of a conventional marine vessel or other target section of such a marine vessel with a non-slip layer shaped as the cushion layer, or with an additional front section, and/or additional rear section permanently attached to the top surface of the cushion layer. The cushion layer additionally includes a tapered edge on its top surface and a plurality of fastener strips for enabling removable attachment to the surface of the boat deck on its bottom surface.

Low-density thermoplastic expandable microspheres are disclosed. Various low-density structures, in particular, sandwich panels, based on foam prepared from the low-density microspheres, are also disclosed. Process of preparing low-density polymeric microspheres, per se, and the corresponding low-density structures, based on the microsphere foam, are also disclosed.

An aluminum alloy material is provided. The aluminum alloy material has excellent bonding durability and is not susceptible to decrease in the bonding strength even if exposed to a high-temperature humid environment. A bonded body, a member for automobiles, and a method for producing the aluminum alloy material are also provided. In the method for producing the aluminum alloy material, the etching amount is controlled to be less than 700 nm when a first film composed of an oxide film is formed on the surface of an aluminum alloy base; and after the formation of the first film by a treatment using an aqueous solution containing a silicate salt, which is the final stage of the substantial film formation, a second film having a siloxane bond is formed by performing a silane coupling treatment.
