types of conventional composite materials. conventional wood composite materials fall into five main categories based on the physical configuration of the wood used to make the products: plywood, oriented strandboard, particleboard, hardboard, and cellulosic fiberboard.
application of time temperature stress superposition on creep of wood plastic composites. the shift factor was independent of the stress for horizontal shifts in time temperature superposition. in addition, the temperature- and stress-shift factors used to construct master curves were well fitted with the wlf equation.
