Abstract:
The present invention provides a joining method using a method of laser welding wherein two resin molded bodies (1,2) can be joined with high welding strength. Specifically, this is a method that joins two thermoplastic resin molded bodies using a method of laser welding; the first resin molded body (1) is a laser light transmissive molded body comprising a thermoplastic resin and cellulose fibers with an α-cellulose content of 80% or more; the second resin molded body (2) is a laser light absorbent molded body containing a thermoplastic resin and a colorant; and the first resin molded body (1) and the second resin molded body (2) are welded by irradiating laser light from the first resin molded body (1) side.
Abstract:
The present invention is directed to a method of making a flexible hose (10), comprising the steps of extruding a first poly(vinyl chloride) compound to form a tube (1), the tube having an inner cylindrical cavity coextensive with the tube; a) applying a textile reinforcement (5) over the tube; b) extruding a second poly(vinyl chloride) compound over the textile reinforcement to form a cover layer (6), said tube, reinforcement and cover layer defining a hose composite; c) inserting a rigid mandrel into the inner cylindrical cavity; d) wrapping a fabric wrap around the outside of the cover of the hose composite; and e) processing the wrapped hose composite at a temperature in a range of 130° to 160°C and a pressure of 30 to 70 psig for a time ranging from 5 to 40 minutes.
Abstract:
The present invention relates to the treatment or prevention of skeletal disorders, in particular skeletal diseases, developed by patients that display abnormal increased activation of the fibroblast growth factor receptor 3 (FGFR3), in particular by expression of a constitutively activated mutant of FGFR3.
Abstract:
Fibrous materials, compositions that include fibrous materials, and uses of the fibrous materials and compositions are disclosed. For example, the fibrous materials can be operated on by a microorganism to produce ethanol or a by-product, such as a protein or lignin.
Abstract:
A composite material panel includes a substrate formed of a first material; one or more strands formed from a second material, the strands being interspersed through the substrate, the second material being a natural material, the second material providing modified mechanical properties of the composite material panel.
Abstract:
In a method for controlling shrinkage of a composite, a dried hydrophobically modified cellulose-based fiber is exposed to a slow acting resin system having a first curing time. An excess amount of the slow acting resin system is removed to separate out the pre-wetted hydrophobically modified cellulose-based fiber. The pre-wetted hydrophobically modified cellulose-based fiber is mixed with a fast acting resin system to form a mixture. The fast acting resin system has a second curing time that is less than the first curing time. The mixture is molded at a predetermined temperature. The fast acting resin system is cured prior to the slow acting resin system, and the slow acting resin system flows into free space within the curing fast acting resin system prior to the slow acting resin system being cured.
Abstract:
A nonwoven trough and method of construction thereof are provided. The nonwoven trough includes at least one nonwoven wall formed from a mixture of bonded natural cellulosic fibers and thermoplastic fibers. The at least one nonwoven wall extends along a longitudinal axis and has a midsection and opposite end portions. The midsection has a base and a pair of walls extending upwardly from the base to provide the midsection with a generally U-shaped cross-section taken generally transversely to the longitudinal axis. At least one flange extends laterally from the at least one nonwoven wall, wherein the flange is configured for attachment to a vehicle member.
Abstract:
A sheet manufacturing method includes defibrating a defibration object into a defibrated material in the atmosphere, mixing, in the atmosphere, additive agents including resin into the defibrated material that has been defibrated, adding moisture to a mixture of the defibrated material and the additive agents after the mixing is completed, and heating the mixture that has been moisture-added.
Abstract:
A reinforced polymer composite includes a polymer matrix and a strengthening agent. The strengthening agent includes highly crystalline cellulose nanocrystals (CNC) and a stabilizing agent. The crystalline cellulose nanocrystals (CNC) have dimensions of about 3 to 5 nm in width and about 100 to 300 nm in length and a density of about 1.6 g/cm3 and the stabilizing agent may be one of Boehmite nanoclay (Boe) and Cetyltrimethylammonium Bromide (CTAB) or a combination of both.
