405 results about "Heat fusion" patented technology

Heat fusion (sometimes called heat welding, butt welding or simply fusion) is a welding process used to join two different pieces of a thermoplastic. This process involves heating both pieces simultaneously and pressing them together. The two pieces then cool together and form a permanent bond. When done properly, the two pieces become indistinguishable from each other. Dissimilar plastics can result in improper bonding.

Method for rapid forming of a ceramic work piece

An inorganic binder and a dissolving agent are put into ceramic powder. They are mixed to form a plastic green mixture. Then the said mixture is formed into a thin green layer. Preferably, this thin green layer will be preheated and dried such that the thin green layer will be hardened due to the bonding effect of the inorganic binder. A portion of the thin green layer exposed under a directed high-energy beam is sintered, preferably by a laser beam, to cause ceramic molecules to bond together locally due to heat fusion. By controlling the scanning path of the high-energy beam, a two-dimensional thin cross section of the ceramic part in arbitrary form can be produced. A second thin ceramic layer can be built onto the first thin ceramic layer and bonded to it by the same method. After multiple repetitions of this procedure a three dimensional ceramic part can be fabricated layer upon layer. The green portion, which is not scanned by the high-energy beam, will be removed with suitable method. A ceramic part can be rapidly produced in this way.

Composite structural panel with thermoplastic foam core and natural fibers, and method and apparatus for producing the same

A composite structural panel includes a cover sheet laminated onto a three-layered substrate including a thermoplastic foam core sandwiched between two composite outer layers. Each composite outer layer includes natural fibers embedded in a thermoplastic matrix. The thermoplastic material of all layers is preferably polypropylene, and the core consists of an expanded cellular polypropylene rigid foam. In a method for forming the composite structural panel, a first preheated outer layer is laminated and molded onto the foam core in a first molding step, and then the second preheated outer layer and the cover sheet are laminated and molded onto the foam core in a second molding step, with a cooling-down time allowed between the two molding steps. In this manner, each preheated outer layer provides enough heat to thermally fuse the outer layer onto the foam core, without overheating the foam core to the point of softening or melting the foam core. The low density foam core provides a spacing distance between the strong composite outer layers, and therefore the finished composite structural panel has a high strength and rigidity, and a high strength-to-weight ratio. The structural panel can be molded into any desired three-dimensional contoured configuration during the molding process.
