A curved, three-dimensional, ordered micro-truss structure including a series of first struts extending along a first direction, a series of second struts extending along a second direction, and a series of third struts extending along a third direction. The first, second, and third struts interpenetrate one another at a series of nodes. The series of first struts, second struts, third struts, and nodes form a series of ordered unit cells within the micro-truss structure. The series of ordered unit cells define a curved surface.

A method for manufacturing a part made of composite material including a thermoplastic or thermosetting matrix reinforced with fibers includes the following steps: winding or depositing pre-impregnated fibers about a mandrel so as to form a preform, the fibers being formed of a thermoplastic or thermosetting material and being pre-impregnated with a thermoplastic or thermosetting matrix; winding a heat-shrinkable film around the preform; polymerizing the intermediate product obtained by winding the film about the preform at a polymerization temperature depending on the composite material used; and removing the heat-shrinkable film from the intermediate product so as to obtain a one-piece part made of composite material and including the mandrel.

A composite material includes a laminate in which fiber sheets are laminated. The laminate has a bendable portion that is to be bent along a mold. In a region of the laminate from an end edge on a bent side to the bendable portion, the laminate is divided into layers along a plate thickness direction of the laminate.

A nylon tube automatic thermoforming apparatus includes a main body, a conveying assembly, a heating assembly and a tube bending assembly. The heating assembly includes an oven communicated with the conveying assembly and an electrically heated cylinder arranged between the oven and the tube bending assembly. A heating coil is arranged in the electrically heated cylinder. A nylon tube is conveyed from the conveying assembly and enters the tube bending assembly via the oven and the heating coil. The electrically heated cylinder and the tube bending assembly are arranged outside the main body. A nylon tube shaping process includes the steps of drawing, heating inside a main body, heating outside the main body, bending, staying, feeding, angle adjusting, repeating the above steps until the length and the curvature of the nylon tube meet the requirements, and cutting off.

A portable vinyl sheet bending apparatus having an arcuate assembly for contacting a plastic composite member and a frame having a substantially planar frame base member. The apparatus includes a heating assembly mounted within the frame of the machine to provide uniform heat to a plastic composite member such that the temperature of heat provided allows for the plastic composite member to become pliable. The arcuate assembly includes two cylindrical rotator bars and a rotatable arcuate arm member for arcuately forming an edge of the planar plastic composite member between and around the cylindrical rotator bars.
