Wood plastic composite (WPC) boards are an emerging engineered wood composite that is a substitute for solid wood and other wood composite materials used for exterior applications, primarily decking. We are interested in understanding the strength of these boards and knowing when the lower percentiles fail under perpendicular pressure. The strength of WPC is determined by the perpendicular pressure required to permanently deform a board (modulus of elasticity and abbreviated as MOE), and the perpendicular pressure required to rupture the board (modulus of rupture and abbreviated as MOR). Two WPC production size extrusion lines at the same facility are compared in this paper by comparing the distributions of pressure to failure for samples of WPC extruded from each line. Parametric bootstrapping is used to calculate confidence intervals of the first, fifth, and tenth percentiles of the MOE and the MOR from each line. Furthermore, nonparametric bootstrapping is performed to estimate confidence intervals on the differences between the two lines for the first, fifth, and tenth percentiles of the MOE and the MOR. A statistical difference between the strength of the WPC extruded from the two lines is found in the MOR.
