Abstract

See full text

A durable palm fiber composite material is obtained by impregnating an unprocessed palm bark in a resin adhesive solution prepared by using a palm leaf as a raw material and then hot-pressing. The palm bark is dried under a natural state without additional processing. The palm leaf is made into a tannin resin adhesive solution under the effect of additives such as furfuryl alcohol, paraformaldehyde, and others. A pH value of the adhesive solution is controlled to be 9-11. A solid content is 40-60%. An adhesive amount applied to the palm bark by the resin adhesive solution is 800-1500 g/m2. Odd number of layers (three or more layers) of palm barks that are impregnated by the resin adhesive solution and are hot-pressed to the composite material. Hot-pressed parameters are as follows: the temperature is 150-180° C. the unit pressure is 0.8-1.5 MPa, and the time is 10-30 s/mm.
