A method of forming a three-dimensional object, wherein said three-dimensional object is an insert for use between a helmet and a human body, is described. The method may use a polymerizable liquid, or resin, useful for the production by additive manufacturing of a three-dimensional object, comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component.

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.

A composite charge is formed between two compression dies into a composite laminate stiffener. The stiffener is contoured along its length by contouring the dies. Wrinkle diffusers attached to, or embedded or incorporated into the tool surfaces of the dies, diffuse wrinkles formed on the inside radius of the stiffener during the contouring.

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.

A method of forming a three-dimensional object 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 including 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 polymer scaffold from the first component and also 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, and containing the second solidifiable component carried in the scaffold in unsolidified and/or uncured form; and (d) concurrently with or subsequent to the irradiating step, solidifying and/or curing the second solidifiable component in the three-dimensional intermediate to form the three-dimensional object.

A novel tubular or profile shapes of co-extruded multilayer polymers. These materials contain tens to thousands of layers of milli-, micro- to nano-polymer layers. These new shapes contain contiguous layers of milli- to nano-polymer layers in three dimensions and these contiguous layers may be twisted or turned to further expand the potential microlayer geometries.

The present relates to a device and a procedure for the extrusion and application of a spacer profile of insulating glass, particularly for a machine adapted to compose the spacer frame directly against one or more glass panes constituting the insulating glass starting from a thermoplastic product prevalently contained in drums, displacing the extrados thereof to an adjustable and controlled distance referred to the margin of one or more glass panes.

A desired shape can be easily realized, and a decrease in strength can be inhibited. A method for producing a composite material includes: an insertion step of inserting an inner member in which a second reinforcing fiber is impregnated with a resin into a space of an outer member that is formed of a woven first reinforcing fiber extending in an undulating manner, the outer member including an opening that is provided at at least one end portion and the space that communicates with the opening; and a composite material forming step of forming a composite material in which the outer member and the inner member are joined to each other by curing the resin of the inner member to join the outer member and the inner member to each other.
