Abstract
Wood pulp fibers can be hot-pressed to form binder-less high-density fiber network sheets of improved mechanical properties, competing with polymer matrix biocomposites. We have investigated hot-pressing, microstructure, and mechanical properties of eco-friendly and low energy-demand chemi-thermomechanical (CTMP) wood fibers and achieved higher density and better properties than previously reported. The hollow, tube-shaped fibers collapse and form dense networks with heterogeneous pore distribution. The highest pressing temperature (200°C) resulted in the highest strength properties, suggesting that improved interfiber adhesion could further improve mechanical properties.

Supporting Information: Hot-pressing of eco-friendly CTMP wood fiber networks for mechanical performance and low porosity
Description
It provides comprehensive data and analysis on the properties, structure, and energy consumption of chemithermomechanical pulp (CTMP) fiber sheets made from aspen, birch, and spruce. The analysis covers fiber characterization, mechanical properties, microstructural analysis, and energy consumption calculations.
