The present invention relates to: a liquid crystal polyester resin composition which contains a liquid crystal polyester resin and carbon fibers with a sizing agent; and a method for producing this liquid crystal polyester resin composition. The content of the carbon fibers with a sizing-agent is from 5 parts by mass to 120 parts by mass relative to 100 parts by mass of the liquid crystal polyester resin. With respect to the carbon fibers with a sizing-agent, the adhesion amount of the sizing agent with respect to the carbon fibers is from 0.1 parts by mass to 1.2 parts by mass relative to 100 parts by mass of the carbon fibers. If the carbon fibers with a sizing agent are heated from 25° C. to 400° C. in the air at a heating rate of 50° C./min, the mass loss rate within the range from 300° C. to 400° C. is less than 0.8% by mass.

The present invention relates to an injection molded product including a thermoplastic resin and a fibrous filler, wherein the thermoplastic resin includes at least 10% by mass of at least one selected from the group consisting of polypropylene and liquid crystal polyesters based on the total amount of the thermoplastic resin, the proportion of the fibrous filler having a fiber length of 1 mm or less in the injection molded product is 40% by mass or less based on the total amount of the fibrous filler, and a vertical-horizontal plane area of a test piece after ashing, which is determined by a specific ashing test, is at least 3.5 times the vertical-horizontal plane area of the test piece before ashing.

The disclosure is of and includes at least an apparatus, system and method for a print head for additive manufacturing. The apparatus, system and method may include at least two proximate hobs suitable to receive and extrude therebetween a print material filament for the additive manufacturing, each of the two hobs comprising two halves, wherein each of the hob halves comprises teeth that are offset with respect to the teeth of the opposing hob half; a motor capable of imparting a rotation to at least one of the two hobs, wherein the extrusion results from the rotation; and an interface to a hot end capable of outputting the print material filament after at least partial liquification to perform the additive manufacturing.

A nozzle assembly for a printer head of a 3D printer includes a guide held in a fixed position relative to the printer head and extending from a first end to a second end along a longitudinal axis. A drive mechanism extends from a feed end to a discharge end along the longitudinal axis. The feed end defines a feed opening for receiving a filament from a feed system, and the discharge end defines a discharge opening for discharging the filament from the nozzle assembly. The drive mechanism is movable relative to the guide, and the drive mechanism includes a drive surface for engaging the filament and causing the filament to move from the feed opening to the discharge opening, in response to the drive mechanism moving relative to the printer head. The nozzle assembly further includes a motor for moving the drive mechanism relative to the printer head.

The invention relates to a process for the production of a tape comprising a plurality of impregnated continuous multifilament strands and a polymer sheath which intimately surrounds the plurality of impregnated continuous multifilament strands, wherein each of the plurality of impregnated multifilament strands extends in the longitudinal direction, wherein each of the plurality of impregnated continuous multifilament strands comprises at least one continuous glass multifilament strand, wherein the at least one continuous glass multifilament strand is impregnated with an impregnating agent, wherein the process comprising the steps of a) unwinding from a package the continuous glass multifilament strands, b) applying the impregnating agent to the continuous glass multifilament strands to form the plurality of impregnated continuous multifilament strands, c) placing the plurality of impregnated continuous multifilament strands in parallel alignment in the longitudinal direction and d) applying a sheath of a thermoplastic polymer composition around the plurality of impregnated continuous multifilament strands of step c) to form the tape, wherein steps c) and d) are performed in a die having a guiding means arranged for placing the plurality of impregnated continuous multifilament strands in parallel alignment in the longitudinal direction, wherein the plurality of impregnated continuous multifilament strands pass through a melt of the thermoplastic polymer composition inside of the die downstream of the guiding means.

A pressurizing pre-impregnating die head for a fiber reinforced plastic sheet machine is provided. The die head includes a body; at least one group of fiber channels arranged in a longitudinal hole-through manner in a middle of the body, and a fiber yarn conveyed in the fiber channel. The body includes a feeding port and discharging ports, which communicate with each other. The discharging ports are located in outer sides of the fiber channel. Thermoplastic base materials in a molten state are paved on two sides of the fiber yarn. The thermoplastic base materials may be paved on surfaces of the two sides of the fiber yarn when being extruded.

The invention relates to an extruder system and a method for extruding cord reinforced extrudate, in particular for tire components, wherein the extruder system comprises an extruder head with flow channels for receiving an extrusion material from an extruder, a die for receiving said extrusion material from the flow channels and a cord guide for guiding cords side-by-side in a cord plane into the die, wherein the extruder head is provided with an insertion slot that extends in an insertion direction parallel to the cord plane through the extruder head, wherein the flow channels debouch into the insertion slot at a flow area, wherein the insertion slot is arranged for receiving the die and the cord guide in the insertion direction into a die position downstream of the flow area and a cord guide position upstream of the flow area, respectively, with respect to the insertion direction.
