Composite material and method for making the same
A method for making a composite material comprises: (i) providing a mixture comprising:(a) carbon fibres and/or lignocellulosic biomass fibres, preferably straw; and (b) at least one phenolic resin; (ii) providing an aqueous composition comprising aluminium dihydrogen phosphate and, optionally, alumina powder, having a pH of from 0.0-2.0, preferably 0.6-1.0; (iii) introducing the mixture into a mould and compressing the mixture within the mould to form a moulded body; (iv) heating the moulded body under an inert atmosphere to pyrolyse the at least one phenolic resin to form a porous body; (v) infiltrating the porous body with the aqueous composition to form an infused porous body; and (vi) drying and curing the infused porous body to form the composite material. The infiltration aqueous composition is preferably sodium and/ot potassium silicate.
