A reinforcing bar comprising a core is provided. The core comprises ultra-high-molecular-weight polyethylene fibers aligned in an axial direction and a polyethylene matrix. The ultra-high-molecular-weight polyethylene fibers are bound in the polyethylene matrix. A shell comprising ultra-high-molecular-weight polyethylene tape surrounds the core in a radial dimension.

The present disclosure relates to the field of building materials. In particular, the present disclosure relates to fiber cement production methods and processes that exhibit high solid retention capacity in the dewatering step, providing increased productivity and potentially other process gains related to the lower concentration of solids and additives in the process water.

A building panel with a high degree of isotropy with regard to the load bearing capacity and flexural strength. The building panel includes a first section and a second section, each section including at least one layer, each of the at least one layer having fibers, whereby the fibers are distributed substantially homogeneously throughout each layer, substantially parallel to the main surfaces of the panel and oriented predominantly in the same direction and the sections are firmly joined in transverse direction, and the first section is thinner than the second section.

Mat-faced cementitious board including: (a) a cementitious core; (b) a fibrous mat having an inner first surface facing at least one face of the cementitious core, and an outer second surface, wherein the inner first surface and the outer second surface are opposed; (c) a hydrophobic, non-setting coating resulting from applying to the outer second surface of the fibrous mat a layer of hydrophobic finish composition including: (i) about 50 to about 80 weight % non-setting, inorganic filler having a mean particle diameter of about 12 microns to about 35 microns, (ii) about 20% to about 50 weight % an aqueous dispersion of a film-forming polymer, (iii) 0% to about 30 weight % additional water; (iv) an absence of fly ash, (v) an absence of pozzolanic material, (vi) an absence of hydraulic cement, (vii) an absence of calcium sulfate hemihydrate, and (viii) an absence of calcium sulfate anhydrite.

A fiber reinforced polymer rebar composition and a method of forming the rebar composition is described. The method includes the steps of feeding a first fiber and a second fiber simultaneously through a preforming guide into a resin impregnator, pulling the fibers through the liquid polymeric resin in the resin impregnator to form a resin-soaked hybrid fiber, and passing the resin-soaked hybrid fiber through a heated stationary die where the resin of the resin-soaked hybrid fiber undergoes polymerization and cross-linking.

Disclosed is a method of making high temperature fiber including chemically bonding high temperature material to a fiber template at a first temperature to form a precursor fiber and processing the precursor fiber at a second temperature to form the high temperature fiber. The first temperature does not equal the second temperature. Also disclosed are high temperature fibers made by the method.

A cladding system for use on the external surface of a building structure that includes a continuous rail system to attach a cladding panel that interlocks with itself. The rail system includes a tongue and groove system to attach the cladding system to the building thereby avoiding the need to use discrete anchors. The cladding panel is formed of a high strength concrete matrix and, optionally, a plurality of twisted steel micro reinforcements (TSMR) dispersed therein.

A lightweight insulative and fire-retardant building material and component and manufacturing process are disclosed. The building material is based on cellulose impregnated with clay and can be formed in the form of posts, columns, bricks, blocks, and panels.

Mat-faced cementitious board including: (a) a cementitious core; (b) a fibrous mat having an inner first surface facing at least one face of the cementitious core, and an outer second surface, wherein the inner first surface and the outer second surface are opposed; (c) a hydrophobic, non-setting coating resulting from applying to the outer second surface of the fibrous mat a layer of hydrophobic finish composition including: (i) about 50 to about 80 weight % non-setting, inorganic filler having a mean particle diameter of about 12 microns to about 35 microns, (ii) about 20% to about 50 weight % an aqueous dispersion of a film-forming polymer, (iii) 0% to about 30 weight % additional water; (iv) an absence of fly ash, (v) an absence of pozzolanic material, (vi) an absence of hydraulic cement, (vii) an absence of calcium sulfate hemihydrate, and (viii) an absence of calcium sulfate anhydrite.

A heat insulating material is a sheet including a fiber and an aerogel. The fiber is aligned in a certain direction in the sheet. A heat insulating structure is used that includes: a high-temperature unit; a low-temperature; and the heat insulating material joining the high-temperature unit and the low-temperature to each other. The certain direction of the heat insulating material is a direction in which the high-temperature unit and the low-temperature unit are joined to each other. A heat insulating structure is used that includes: a first battery cell; a second battery cell; the heat insulating material disposed between the first battery cell and the second battery cell; and a cooling plate that is in contact with the first battery cell, the second battery cell, and the heat insulating material.
