PURPOSE: To obtain a lightweight structural material having high rigidity, formable even at a low temperature or room temperature and useful as an interior material for vehicle by impregnating a polyhydric phenol-aldehyde condensate in fibers and curing the condensate simultaneously with thermal forming. CONSTITUTION: The objective structural material is produced by impregnating (A) jute fibers or a mixture of jute fibers and other fibers with (B) a polyhydric phenol-aldehyde condensate and optionally (C) a curing agent (preferably hexamethylenetetramine or an alkylolated triazone derivative) and curing the component B simultaneously with the thermal forming of the mixture to a prescribed form. The component B is preferably a sulfomethylated cocondensation product of a polyhydric phenol (especially an alkylresorcinol), a monohydric phenol and/or an amino compound monomer and an aldehyde and/or an aldehyde donor. |
