Abstract: A cementitious composite for in-situ hydration includes a first layer, a second layer spaced from the first layer, and a cementitious mixture disposed between the first layer and the second layer. The cementitious mixture includes cementitious materials. The cementitious mixture is configured to absorb a mass of water that provides a maximum 28 day compressive strength of the cementitious composite upon curing which is represented by Mw=x·Mc. Mw is the mass of the water per unit area of the cementitious composite. Mc is a mass of the cementitious materials of the cementitious mixture per unit area of the cementitious composite. x is a ratio of the mass of the water relative to the mass of the cementitious materials of the cementitious mixture per unit area of the cementitious composite that provides the maximum 28 day compressive strength of the cementitious composite. x is between 0.25 and 0.55.
Abstract: Disclosed therein is a reinforced leather. The reinforced leather includes: a leather sheet layer made of a leather-like material; a bonded layer positioned on an upper face of the leather sheet layer; a textile layer positioned on an upper face of the bonded layer and made of cotton fabrics; and a coated layer positioned on an upper face of the textile layer. The reinforced leather can remedy the shortcoming that leather-like materials produced from waste resources get torn easily, be used as leather for shoes due to its high tensile strength and shear strength, and provide a beautiful appearance.
Abstract: Methods to produce structures containing ultrafine fibers with average diameters from 10 nm to 10 ?m and more preferably from 50 nm to 5 ?m, have been developed. These methods produce ultrafine fibers without substantial loss of the polymer's weight average molecular weight. The ultrafine electrospun fibers have an unexpectedly higher degree of molecular orientation, and higher melt temperature than fibers derived by dry spinning. In the preferred embodiment, the polymer comprises 4-hydroxybutyrate. The ultrafine fibers are preferably derived by electrospinning. A solution of the polymer is dissolved in a solvent, pumped through a spinneret, subjected to an electric field, and ultrafine fibers with a high degree of molecular orientation are collected. These structures of ultrafine fibers can be used for a variety of purposes including fabrication of medical devices.
