Water cure methods for producing three-dimensional objects from materials having multiple mechanisms of hardening
A method of forming a three-dimensional object (e.g. comprised of polyurethane, polyurea, or copolymer thereof) is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; (b) filling the build region with a polymerizable liquid, the polymerizable liquid comprising a mixture of: (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from the first component; (c) irradiating the build region with light through the optically transparent member to form a solid blocked polymer scaffold and advancing the carrier away from the build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, the three-dimensional object, with the intermediate containing the second solidifiable component; and then (d) contacting the three-dimensional intermediate to water to form the three-dimensional object.
SUPPORTING ROD OF VEHICLE COMPONENT, SYSTEM OF INTEGRATING SUPPORT AND VIBRATIONAL DAMPING AND PROCESS FOR MANUFACTURING OF A SUPPORTING ROD OF VEHICLE COMPONENT
A multifunctional supporting rod of vehicle components of commercial vehicles, such as road implements, including, e.g., rods useful in supporting of vehicle components like fender, wings, rearview mirrors, lighting devices for commercial vehicles and similar, among other parts. In one aspect, the rod includes an integrated shock absorber for vibrational efforts and load in rod itself, comprising structural composite material, which provides improved dampen of mechanic-dynamic efforts and improved mechanic responses, reducing structural fatigue. In other aspect, the rod provides higher resistance to efforts, less material amount, and provides a mode of incomplete failure in predetermined location, avoiding loss of components during a structural failure generated from use. In another aspect, the rod has low weight/mass, provides gain of payload of commercial vehicle, and economy of energy/fuel.

These products lead to a significant reduction in weight and reduction in density with higher stiffness and bending strength. The present bio-composite products are encapsulated by fabrics in the peripheral area brings more integrity uniformity of jute materials. This leads to a significant cost reduction in a without sacrificing much tensile strength.
METHOD AND APPARATUS FOR PRODUCING POROUS PLASTIC PROFILES
A method is disclosed for manufacturing connectable or non-connectable elongate porous plastic profiles 12 from substantially continuous randomised extruded plastic strands made of recycled thermoplastics. Current manufacturing processes can manufacture similar products, comprising short partially melted plastic particles melded together forming planks. These planks, however, are inherently friable, easily broken and not readily connectable. These shortcomings are caused by the manufacturing method used, being friction plate agglomeration. This invention utilises an extrusion process, which produces substantially endless random strands of thermoplastic 13 which drop and are welded together to form a porous mass, which is then compressed into boards or planks by pulling the mass through a forming tool 6 and 7. The profile can be adjusted to form edge recesses allowing the planks to be fitted together, for instance to form area coverings, or they can simply be laid end to end to form drainage channels.

The present invention relates to a system for producing structural profiles by means of continuous fibre braiding, which comprises: a machine for braiding fibres around a mandrel, the forward movement of which defines a longitudinal axis of the system; a module for injecting resin into the braided fibres; a module for curing the resin-impregnated fibres; a device for inserting and removing the mandrel; and a device for pulling the profile, wherein the braiding machine is a dual braiding machine connected to a respective fibre-reloading machine.
Device and method for more efficient sizing of a complex extruded plastic profile
Plastic profile extrusion system includes an extrusion die that pre-forms a hot, unfrozen plastic profile shape. Cooled calibration device receives the hot plastic in a longitudinal cavity through the calibration device to conductively cool the plastic as it holds the plastic profile to size and dimensions. For plastic parts with channels, inside corners, or other difficult to cool sections, the calibration device would require a metal ridge to hold the shape of that channel or corner as the heat is conducted from the hot plastic through the metal ridge into the body of the calibration device. This invention replaces metal ridges that hold the shape of the plastic profile during cooling in at least part of the calibration device with fluid cooling passages that communicates with the moving portion of the plastic profile and cooling medium to fill the flow passages to extract heat from the plastic material.
