METHOD AND APPARATUS OF MANUFACTURING RESIN COMPOSITE MATERIAL
An apparatus and a method of manufacturing a resin composite material that are capable of stabilizing a raw-material supply amount and improving manufacturing efficiency of the resin composite material are provided. The apparatus 10 of manufacturing the resin composite material includes: a raw-material supply portion 11 supplying a thermoplastic resin and moisture-absorbent filler; a first cylinder 12; a first degassing portion 13 provided in the first cylinder 12; a die 14 for extrusion molding; and a rotary drive mechanism 15 driving a first screw, and is capable of removing volatile gas generated from a kneaded material of raw materials from inside of the first cylinder 12 to outside by using the first degassing portion 13.
EXTRUDER VENT FLOW SENSOR
Disclosed are techniques for mitigating vent flow into a vent attachment on an extruder vent of an extruder. The vent attachment has a vent attachment port configured to release gases from the extruder vent. The techniques include monitoring temperature via a temperature probe mounted at least partly inside an interior opening of the vent attachment. The temperature probe is communicatively coupled to a programmable logic controller (PLC). A region of the vent attachment adjacent the temperature probe is cooled so as to reduce an operating temperature of the region and of the temperature probe. Vent flow is detected in response to the PLC determining a rate of temperature change of the temperature probe exceeding a predetermined threshold rate and thereby indicating presence of the material in the vent attachment port.
Systems and methods for making composite structures
A system for depositing a composite filler material into a channel of a composite structure includes an end-effector configured to extrude a bead of the filler material into the channel. The filler material can comprise a first group of relatively long fibers, a second group of relatively short fibers and a resin. A drive system is configured to move the end-effector relative to the channel, and a position sensor is configured to detect the position of the bead relative to the channel. A controller is configured to operate the drive system in response to the detected position and to operate the end-effector to heat and compress the filler material so as to orient the longer fibers in a substantially longitudinal direction relative to the channel and the shorter fibers in substantially random directions relative to the channel when the bead is extruded into the channel.
GRAIN DEHYDRATING COMPRESSOR FOR WET GRAIN SYSTEM AND METHOD
A device according to various embodiments for preparing wet grain can include at least a first screw configured to receive wet grain. A second screw receives the wet grain from the first screw. At least one of a compressing element and a dehydrating element is included with at least one of the first screw and the second screw to cause a physical property change to the wet grain.
2-STAGE EXTRUSION APPARATUS AND METHOD OF EXTRUSION
A consolidation system configured to consolidate a bulk molding compound, the apparatus comprises a barrel, a low compression first stage within the barrel, a high compression second stage within the barrel coupled with the low compression first stage, a die breaker coupled to the high compression second stage, and an extrusion die coupled to the die breaker. The low compression first stage includes a low compression screw for mixing and compressing a bulk molding compound comprising a resin and fillers. The high compression second stage includes a high compression screw for compressing the bulk molding compound into a compressed material. The die breaker comprises at least one of a plurality of holes or a plurality of slots.
