Abstract | Novel composites bio-resins for civil engineering applications were synthesised and evaluated. PF phenolic resins were modified to enable their application in modern composites structures. A first modification consisted in the copolymerization of Phenol with Cardanol during the synthesis of resol PF resins. The modified phenolic resins (CPF) were prepared at various molar ratios of the total Phenol to Formaldehyde and with different weight ratios of Phenol to Cardanol. CPF resins with a maximum content of 40 wt% of Cardanol were synthesised and used. The CPF resins were applied as a plasticizer and toughening agents to the PF resins. Both resins (CPF/PF) were mixed in different proportions and their thermal and mechanical properties were established. A full miscibility of the two resins was observed with the formation of a single-phase system. An increases in the content of Cardanol resulted in a proportional increases in the flexural strength and in the fracture toughness together with a decreases in the flexural modulus of the cured CPF/PF resins. Further increased plasticizing and toughening effect was observed by the blending of the CPF/PF resins with propylene glycol (PG). The higher toughness and flexibility effect of the CPF resins was obtained with a F:P molar ratio equal to 1.25. An increases in the Cardanol content resulted in a proportional decreases in the final crosslink density and in the ultimate glass transition temperature of the cured composite resins. |
