Abstract
Mechanical and thermal properties of composite materials containing steam-exploded lignin (hereinafter called “lignin”) were investigated. Thermal resistance and mechanical properties of lignin-epoxy resin and lignin-containing phenolic resin were excellent compared with those of using fossil-derived phenolic resin. The resin flow was controlled by optimizing additive amount of resin and filler. The complex shaped molding articles were obtained by compression, transfer and injection molding. Peel strengths of lignin-containing phenolic resin composite materials with aluminum and copper foils were higher than those of composite materials using fossil-derived phenolic resin.
