Delivery of packages by unmanned aerial vehicles
A package delivery apparatus uses an unmanned aerial vehicle (UAV) to deliver a package containing a product to a delivery destination area. The UAV uses GPS signals to guide it to the delivery destination area and an altimeter to determine its height above the delivery destination area. The UAV then adjusts its height to a preferred drop or release height for that package and product and releases the package. An optional camera allows a human operator to view the delivery destination area. An expandable foam package surrounds the product to protect the product from impact and moisture. The package may be streamlined to reduce air resistance and increase the range of the UAV. The package characteristics, such as its thickness, are determined based one or more of the weight and fragile nature of the product, and the drop height.
Composite materials
A composite material that includes a layer of reinforcing fibres impregnated with a curable resin matrix and a plurality of electrically conductive composite particles positioned adjacent or in proximity to the reinforcing fibres. Each of the electrically conductive composite particles is composed of a conductive component and a polymeric component, wherein the polymeric component includes one or more polymers that are initially in a solid phase and are substantially insoluble in the curable resin, but is able to undergo at least partial phase transition to a fluid phase during a curing cycle of the composite material.
Materials comprising shape memory alloy wires and methods of making these materials
Some embodiments relate to non-woven composite materials, methods of making and uses thereof, including articles including the composite structures. More particularly, some embodiments relates to non-woven composite materials possessing desirable impact performance and penetration resistance.
ISOSTATIC SIDE-PRESSURE SHIELDED COMPOSITE CONSOLIDATION
A mold for use in the production of a ballistic article from a composite laminate stacked material wherein the mold has a sliding sealing section that nests with a outer permitter section and base portion so as to shield the sides of the composite laminate stacked material from applied isostatic pressure applied when in an autoclave. By shielding the sides of the composite laminate stacked material excess resin matrix material can be forced from the composite laminate stacked material to provide a uniform composite article with reduced weight and reduced thickness.
METHOD FOR PRODUCING FIBER-REINFORCED POLYBUTYLENE TEREPHTHALATE RESIN COMPOSITION
A method for manufacturing a fiber-reinforced polybutylene terephthalate resin composition contain 40-90 mass % of a polybutylene terephthalate resin, 10-60 mass % of a reinforcing fiber, and 0-35 mass % of other polymer or additive by using a twin-screw extruder, the method includes using polybutylene terephthalate resin pellets (avg. weight of 16-29 mg) as a raw material for the resin by: (1) kneading the resin and the fiber with a first kneading part; (2) adding the fiber at a part downstream of the first kneading part and performing kneading with a second kneading part; and (3) reducing pressure of a vent at a part downstream of the second kneading part and performing devolatilization, where the first kneading part has a length of 5.0-9.0 D and a specific screw configuration, the second kneading part contains a specific screw configuration, and the production is carried out with a screw shaft torque density of 11.5-19 Nm/cm.sup.3.
DECORATED MOLDING ARTICLE
Provided is a decorated molding article includes a workpiece and a molded film attached to an outer surface of the workpiece or an inner surface of the workpiece. Compared with the printing layer in the conventional In Mold Label (IML) and InSert molding (INS) that is made by a plurality of anti-impact and bonding processes, a plurality of stacked decorative layers of the embodiment not only provide various color effects, but also directly combined with injection molding material to form part products and have both a protection effect and an adhesive effect. Further, the present disclosure can effectively simplify the manufacturing steps of the composite layer structure and reduce the manufacturing cost.
METHOD OF FABRICATING LIGHT-TRANSMITTING DECORATED MOLDING ARTICLE
A method of manufacturing a decorated molding article includes: forming an all-in-one coating on a substrate and performing a curing step, thereby forming a composite layer structure with a protective effect, a color effect, and a bonding effect. Compared with the printing layer in the conventional In Mold Label (IML) and InSert molding (INS) that is made by a plurality of anti-impact and bonding processes, the composite layer structure of the embodiment can form a molded film with better physical properties (e.g., higher hardness, better protection effect, etc.) after the blister molding process. Therefore, the molded film of the embodiment can be applied to a laser engraving process to form a variety of light-transmitting decorative molded products. Further, the present disclosure further forms a protective layer locally in the grooves formed after the laser engraving process, so as to protect the texture after the laser engraving process from damage.
