Terahertz spectroscopy has been presented as a new technique for analyzing the degree of dispersion of polymeric compounds It is a contact-free and nondestructive technique that can also be used to monitor the filler content of compounds inline during the extrusion process as has already been presented elsewhere The utilized terahertz frequency range bridges the infrared and the microwave region in the electromagnetic spectrum Here, we present offline terahertz measurements and mechanical tests on injection molded specimens consisting of wood plastic composites with varying filler contents and different dispersion qualities A clear linear relation between results of the terahertz measurements and mec
