Graphene/cardanol modified phenolic resin for the development of carbon fiber paper-based composites

Abstract

Carbon fiber paper-based composites (GCPC) were prepared by impregnating carbon fiber papers in a solution of graphene and cardanol modified phenolic resin (GCP). GCP was characterized by thermal gravimetric analysis (TGA), and the electrical conductivity, mechanical properties, pore distribution, and porosity of GCPC were investigated by a four-probe tester, universal testing machine, microtopography, and porous material analyzer, respectively. The results show that the electrical properties and mechanical strength of GCPC were improved with the increase of graphene and cardanol content. The porosity decreased and the proportion of small holes increased with the increase of graphene, while the porosity increased and the proportion of small holes decreased with the increase of cardanol. When the content of cardanol was 20% (mass fraction), the tensile strength of the composite reached 38.17 MPa, the resistivity reached 18.46 mU cm, and the porosity reached 67.46%.

Environmentally sustainable rice husk ash reinforced cardanol based polybenzoxazine bio-composites for insulation applications

“…Cardanol is used as sustainable raw material source for the production of polymer based industrial products such as laminating resins, polyurethanes based polymers [17], epoxy resins [18,19], phenolic resins [20], friction linings, surfactants, emulsifiers, paints, varnishes and benzoxazine resins. The development of new polymers, especially those based on renewable raw materials, are warranted to replace petroleum feed stocks.…”

The Preparation and Properties of Terephthalyl-Alcohol-Modified Phenolic Foam with High Heat Aging Resistance

“…Phosphate-containing cardanol-modified phenolic resin, prepared by Caiying Bo et al, can overcome the brittleness of the foam, improve its flame retardancy, and attain a high thermal stability and good mechanical properties [18]. In addition, the phenolic resin may be physically modified [19,20]; that is, the modifier is blended with the phenolic resin and then foamed as a matrix resin. Yufeng Ma et al added an environmentally friendly, halogen-free flame retardant, a synergist, and other additives to the phenolic resin and foam, and the obtained modified foam had excellent flame retardancy [21].…”
