The wood-plastic composite (WPC) industry in China has gone through a long learning curve and is ready to take off. A brief development history will be discussed, from WPC pallet, decking, exporting, to the lessons from projects in the 2008 Beijing Olympics, to the wide use of PVC-based WPC in interior housing applications. Emphasis on innovations in the Chinese WPC industry will be detailed. More research and effort has been put in applications, including sound bar, structural and energy saving wall panel, curtain wall, sewage pipe, etc. In the new 12th five-year plan, China will develop 70 million sets of apartments, or a need for over $70 billion in construction materials. Many opportunities exist for WPC in China.

Another kind of sandwich is finding its way into residential and commercial construction as well. Structural insulated panels (SIPs), featuring a core of expanded polystyrene (or in some instances, polyisocyanurate) sandwiched between two thin slices of OSB, are strong, lightweight building products that can be designed to have exceptional insulation properties. For example, spray polyurethane foam (SPF) can be used in wall assemblies to increase the racking loads. The National Association of Home Builders (NAHB) have performance results for racking loads from 1992 for SPFwood-stud panels with 16-inch spacing, showing a 200% increase for panels with vinyl sheathing and an 83% increase for panels with plywood sheathing. NAHB also reports performance results for racking loads in 1996 for SPF-metal wall panels, showing over 100% increase in for panels with drywall sheathing and a 25% increase for panels with OSB sheathing.

Because they are manufactured components, SIPs panels can be delivered to the job site sized for a specific application, with wiring chases and provisions for plumbing rough-in machined or molded into the foam core and the OSB outer panel. Contractors use SIPs in floors, walls, and roofs of residential and industrial buildings. Composite materials are also being used in renovation applications to help strengthen beams, slabs, walls, columns, chimneys, and other structural elements that have been subjected to deterioration, additional service loads or excessive deflection caused by change in use, construction or design defects, code changes and seismic retrofit.

Wrapping masonry in fiber composite materials can significantly increase its strength. This is particularly important in many communities where seismic codes have been tightened and masonry and concrete walls must be upgraded to meet them. The advantages of FRP materials lie in their high tensile strength, low weight, and their ability to conform to varying shapes. The growing use of FRP composites in repair and retrofit of concrete and masonry structures has opened the door for similar applications in strengthening wood beams.
