摘要：A process for the continuous production of a high modulus article comprising a composite of an oriented plastic material and an oriented particulate material, said process including the steps of: a. continuously forcing an orientable plastics material, while it is close to or at its softening temperature and in admixture with an orientable particulate material, through a converging passage of which the cross-sectional area diminishes in the forward direction of plastic flow, thereby to produce an extrudate; b. deforming the extrudate, while it is maintained at or close to its melt temperature, to produce an oriented, deformed extrudate; and c. cooling the deformed extrudate to preserve the orientation and provide said composite. The foamed and unfoamed composite articles have strength, modulus and density values comparable to typical hardwoods or softwoods.
