The poor compatibility between a thermoplastic matrix and natural fiber reinforcement has been limitation in the optimization of fiber‐filled composites. Electron beam irradiation is used to modify structure materials. However, most researches have focused on effect after fabrication Hence, this study was aimed at investigating irradiated recycled polypropylene (i‐rPP) as compatibilizer (rPP) rPP were different doses before compounding process. matrices prepared by mixing unirradiated ratios 90:10 50:50, they compounded with amounts microcrystalline cellulose (MCC) fibers (5, 20, 40 wt%). Radiation crosslinking, functional groups, radical formations, thermal, impact strength characterizations carried out. results showed that simultaneous incorporation i‐rPP MCC significantly improved resistance rPP. synergistic combination higher content (40 wt%) low dose (10 kGy) ratio 50:50 caused degree crosslinking lower concentration. thermal stability acceptable sub‐impact fracture surface analysis revealed effects crack blunting.
