A full-depth ultra-thin long-life pavement structure and a construction method thereof are disclosured. The pavement structure is disposed on a subgrade, and the pavement includes from bottom to top: a composite joint layer, a fatigue-resistant layer, a load-bearing layer, a high-strength bonding layer and a skid-resistant wearing layer; the composite joint layer comprises a bottom layer and an upper layer, the bottom layer is a graded gravel layer, and the upper layer is an open-graded large-particle-size water-permeable polyurethane and gravel mixture layer; the fatigue-resistant layer is paved by a skeleton-interlocking structural polyurethane mixture; the load-bearing layer is paved by a suspended-dense typed polyurethane mixture; the high-strength bonding layer is formed by curing a polyurethane-based composite material; the skid-resistant wearing layer is paved by a high-viscosity and high-elasticity modified asphalt mixture.

A composite textile product includes a polyamide textile layer and a polyamide film. The polyamide film is bonded to the polyamide textile layer. A thickness of the polyamide textile layer is between 0.1 mm and 0.3 mm. The polyamide film has an average pore size ranging from 10 μm to 150 μm. A thickness of the polyamide film is between 0.01 mm and 0.1 mm. Wherein the polyamide film comprises a copolymer material, and the copolymer material includes a polyamide section and a polyether section.

The present application discloses a support film layer and a flexible display panel. By periodically arranging at least one elliptical hollow structure and a plurality of shuttle-shaped hollow structures in a bending region of the support film layer, stress concentrations in the bending region can be weakened, which is beneficial to increase a bending lifespan of the support film layer. The present application can improve an overall ductility of the flexible display panel, increase a bending performance of the flexible display panel, reduce a risk of peeling and fracture between film layers, and increase production yields of products.

The present invention relates to a blow molded plastic container and to a polymer composition from which the blow molded plastic container is made. The blow molded plastic container comprises a pinched seamline and is made by an extrusion blow molding process comprising a pinch step. The present invention also relates to a gas storage tank, comprising the blow molded plastic container as a liner. The polymer composition comprises (a) a polyamide consisting of a copolyamide consisting of repeat units derived from lactam, diamine and dicarboxylic acid, and optionally chain stoppers or branching units or a combination thereof, or of a blend of at least two polyamides, comprising at least one polyamide comprising repeat units derived from lactam, and at least one polyamide comprising repeat units derived from diamine and dicarboxylic acid, and comprising 75-97.5 mole % caprolactam and 1-12 mole % monomer having an aromatic ring, (b) a heat stabilizer and (c) impact modifier.

A flexible insulation material may be configured to substantially reduce the amount of radiation transmitted therethrough by incorporating a reflective mat of high temperature fibers that withstand temperatures of at least 500° C. The flexible insulation may be stored and used over temperatures ranging from −270° C. to 5000° C. The mat may have optical properties to produce a transmittance of no more than 5% over a range of temperature from 500° C. to 5000 vC. The mat may include high temperature fibers such as carbon and/or silicon carbide and these fibers may be coupled by a binder in a non-woven fabric. The flexible insulation material may be configured in the Flexible Thermal Protection System of a deployable aerodynamic decelerator or a Hypersonic Inflatable Aerodynamic Decelerator and may be durably flexible.

Hemp fibers may be disposed throughout or in selected portions of a hose (e.g., an expandable water hose). The hemp fibers deployed in the hose enhance the durability of the hose, and imparts various advantageous properties (e.g., anti-microbial or anti-bacterial, mildew-resistant, odor reduction, moisture wicking, etc.) to the hose.

In accordance with one embodiment of the present disclosure, a method for manufacturing a honeycomb core sandwich panel includes placing a thermoset facesheet in contact with a thermoplastic honeycomb core without using a separate adhesive and attaching the thermoset facesheet to the thermoplastic honeycomb core by using a curing profile comprising a temperature that is lower than a gel point temperature of the thermoset facesheet and higher than a softening point temperature of the thermoplastic honeycomb core.

A flat flexible hose for transporting a fluid, for example water, is adapted to move between an inoperative position having a flattened configuration and an operative position, in which the hose expands radially under pressure from the fluid. The hose has a first inner layer defining an axis, a second covering layer, and a reinforcement textile layer therebetween. The first and second layers are made of a first and respectively a second thermoplastic elastomeric material adapted to adhere to each other. The reinforcement textile layer is made of rigid textile yarns which at least partially have a respective first and second predetermined inclination opposite to each other so that the length of the hose remains unchanged both in the inoperative and the operative positions. The reinforcement textile layer is a knitted layer with tricot chain stitches with rows of stitches and courses of stitches made of chain stitches.

Provided is a low-density clad steel sheet having excellent formability and fatigue properties, including a base material; and cladding materials provided on both side surfaces of the base material, wherein the base material is a lightweight steel sheet including, by weight, C: 0.3 to 1.0%, Mn: 4.0 to 16.0%, Al: 4.5 to 9.0%, and a remainder of Fe and inevitable impurities, and each of the cladding materials is martensitic carbon steel including, by weight, C: 0.1 to 0.45%, Mn: 1.0 to 3.0%, and a remainder of Fe and inevitable impurities.
