The present invention comprises a concrete building system with a method for fabricating composite panels using an improved design plastic connector and assembling them at the construction site to a structure which will be shotcreted on both sides to a concrete building which is highly insulated, is fire and termite proof, hurricane, earthquake and flood resistant and fulfills the requirement for flexible design. The Composite Panels are composed of two concrete layers, enclosing an insulative foam core. The skins are reinforced with wire mesh as structurally required and are connected through the foam core by structural highly insulative plastic connectors using the snap connection on both ends of the connectors so they form a tri-dimentional system and hold the wire mesh in place for the onsite shotcrete application, which includes an application of fiber for shrinkage and cracking. This replaces the welded wire fabric use for secondly reinforcing and let the wire mesh reinforcing only related to the structural strength of the composite panel. The plastic connector guarantees that no thermal bridging occurs like in other systems also the inside layer of the shotcrete panel.

The environmental protection shelving combination of the present invention includes sleeves and panels made of corner protection paper for support and plastic connector sets used for coupling the sleeves. Therefore, in accordance with different requirements, the assembly thereof can be altered as desired. Furthermore, since the corner protection paper is formed by pressing Kraft paper and the sand tube paper into a supporting structure, it can provide bearing and pressure capability, so that can replace the conventional wood, plastic or metal framework. Accordingly, not only the costs of material, conveying and assembly can be reduced, the pollution to the environment also can be minimized.

A heat assisted friction stir welding system and fastener for use therewith allows the joining a variety of dissimilar materials, including joining composites and plastics to metal, in which the fastener becomes part of the bond. The fastener can be constructed from multiple materials, allowing for the joining of dissimilar metals. Heating the materials to be joined reduces the clamping force and torque required by the friction stir weld process. The result is a bond that is stronger with less energy input.

A living hinge structure has two plastic side sections and a plastic connecting section, wherein the plastic side sections are integrated with metal supports so as to enhance the strength of the living hinge structure. The metal supports can be metal inserts bonded to the plastic side sections in an over-molding process. Each of the metal supports can be located on the outside surface or the inside surface of the plastic section. When the metal sections are located on the outside surfaces, they can be used to restrict the opening angle of the hinge. The metal supports can also be a part of a device that uses the hinge for mechanically coupling two device parts. As such, the living hinge is directly integrated into the device without the need for post-assembling by using screws, adhesive, welding or heat stacking.

The invention provides a moulded plastic connector in which the mould is not weakened, and in which terminal fittings are not exposed. Portions of a side of a retainer attachment hole 13, which are opposite an insertion hole 14 for a retainer 20, are open to form mould removing holes 15, the remaining portion being covered by a wall 16. This wall 16 reduces the degree to which terminal fittings 19 are exposed from the interior of a housing 10. When a connector C is to be moulded, anterior ends of a first mould 30 (which is removed from the housing 10 via the insertion hole 14) and a second mould 40 (which is removed via the mould removing holes 15) fit together within the retainer attachment hole 13 in a doubled-over manner in a direction which intersects with the direction of mould removal. Consequently, the strength of the moulds 30 and 40 is not decreased.

A new ultrasonic aided laser joining method (UAL) for bonding dissimilar materials has been developed. The method is capable of eliminating the laser-induced bubbles at the bonding faces and to improve the joint strength over that of the conventional laser-assisted metal and plastic joining method (LAMP). Some experiments on joining titanium to polyethylene terephthalate have been conducted to show the superiority of UAL over LAMP. The results showed that the joint strength, measured in terms of failure load, was significantly increased when ultrasonic vibration was employed during laser joining. For the LAMP joined specimens, fracture normally occurred at the metal-plastic interface, whereas for the UAL joined specimens, fracture normally occurred in the parent plastic part. The improvement in joint strength is mainly due to the elimination of pores in the resolidified plastic. In addition, ultrasound vibration promotes chemical bonding between the plastic and metal parts, and this is supported by the XPS results.
