摘要： A composition and a method are provided for graphene reinforced polyethylene terephthalate (PET). Graphene nanoplatelets (GNPs) comprising multi-layer graphene are used to reinforce PET, thereby improving the properties of PET for various new applications. Master-batches comprising polyethylene terephthalate with dispersed graphene nanoplatelets are obtained by way of compounding. The master-batches are used to form PET-GNP nanocomposites at weight fractions ranging between 0.5% and 15%. In some embodiments, PET and GNPs are melt compounded by way of twin-screw extrusion. In some embodiments, ultrasound is coupled with a twin-screw extruder so as to assist with melt compounding. In some embodiments, the PET-GNP nanocomposites are prepared by way of high-speed injection molding. The PET-GNP nanocomposites are compared by way of their mechanical, thermal, and rheological properties so as to contrast different compounding processes.

摘要： The present invention provides a kneading method for a fiber-reinforced thermoplastic resin with which dispersibility of reinforcement fibers is enhanced and sufficient reinforcement fibers having a proper fiber length remain, and a fiber-reinforced thermoplastic resin plasticizing device and an extruding machine for carrying out the method. The kneading method comprises supplying a thermoplastic resin and reinforcement fibers into a cylinder of a plasticizing device, and rotating a screw to obtain a fiber-reinforced thermoplastic resin, wherein the size of a clearance between the bore of the cylinder and the screw is made different between an upstream side in the vicinity of a reinforcement fiber loading port and a downstream side, so that the clearance becomes larger from the vicinity of the reinforcement fiber loading port toward the downstream side compared with the upstream side.

摘要： Provided is an electrically conductive resin composition with which the characteristics inherent in a thermoplastic resin are easily retained and which exhibits more excellent electrical conductivity even if the blending amount of an electrically conductive filler is small. This electrically conductive resin composition contains a thermoplastic resin, such as a polycarbonate or a polyolefin, and an electrically conductive filler, such as a carbon nanotube. This electrically conductive resin composition further contains a dye, such as a perinone-based dye or a disazo-based dye, which is a component for improving electrical conductivity, and this electrically conductive resin composition can be obtained by kneading or molding a raw material mixture containing a thermoplastic resin, an electrically conductive filler, and a dye under a condition of a temperature equal to or higher than the melting point of the thermoplastic resin.

摘要： Rheology-modified, additive-containing ethylenic polymer compositions are prepared in a continuously operated extruder comprising first, second and third zones by a process comprising the steps of:



mixing in the second zone of the extruder an ethylenic polymer and a high-temperature decomposing peroxide at a temperature such that the half-life of the peroxide is equal to or greater than (≥) one minute and for a sufficient period of time to modify the rheology of the ethylenic polymer to produce a rheology-modified, melted ethylenic polymer for transfer to the third zone of the extruder; and
adding to the third zone one or more additives to the rheology-modified, melted ethylenic polymer to produce the rheology-modified, additive-containing ethylenic polymer.

摘要： A method of additively manufacturing propellant elements, such as for rocket motors, includes partially curing a propellant mixture before extruding or otherwise dispensing the material, such that the extruded propellant material is deposited on the element in a partially-cured state. The curing process for the partially-cured extruded material may be completed shortly after the material is put into place, for example by the material being heated at or above its cure temperature, such that it finishes curing before it fully cools. The propellant material may be prepared by first mixing together, a fuel, an oxidizer, and a binder, such as in an acoustic mixer. After that mixing a curative may be added to the mixture. The propellant mixture may then be directed to an extruder (or other dispenser), in which the mixture is heated to or above a cure temperature prior to the deposition, and then deposited.

摘要： A process for continuously preparing a polyolefin composition made from or containing a polyolefin and carbon black in an extruder device. The process includes the steps of supplying polyolefin in form of a polyolefin powder and carbon black to a mixing device; alternatively, (a) measuring the flow rate of the polyolefin powder supplied to the mixing device or (b) measuring the flow rate of the polyolefin pellets prepared in the extruder device; adjusting the flow rate of the carbon black to the mixing device in response to the measured flow rate of the polyolefin powder or adjusting the flow rate of the polyolefin powder to the mixing device in response to the measured flow rate of the polyolefin pellets; melting and homogenizing the mixture within the extruder device; and pelletizing the polyolefin composition into the polyolefin pellets.
