摘要

Wood-plastic composites are being expanded rapidly in these years. To take advantage of the unique characteristics of the wood fiber by combining them with plastic in conventional panel pressing methods, a new wet process was developed to make fiber-reinforced plastic composites using PP and steam-exploded flour from small-diameter loblolly pine. Wet-laid wood fiber/polymer composites were fabricated using a standard TAPP1 handsheet method followed by compression molding to consolidate the mixed mats into panels. MAPP was used as a coupling agent to enhance the strength of PP composites. DMA and DSC measurement led some insights into the structure of composites and SEM was used to observe the interfacial adhesion. The variables that may affect the product properties were investigated as well, which include mat layer number, wood fiber content, MAPP content, fiber dimension, and molding temperature.
