Abstract

A method for thermoforming a reinforced article, comprising: providing a reinforced plastic sheet comprising at least one thermoplastic material and reinforcement nanoparticles dispersed within the at least one thermoplastic material, the reinforcement particles comprising less than 15 % of a total volume of the plastic sheet, at least 50 % of the reinforcement particles having a thickness of less than about 20 layers, and at least 99 % of the reinforcement particles having a thickness of less than about 30 layers; preheating said plastic sheet;
communicating said preheated plastic sheet to a first mold assembly having a first mold cavity defined by mold surfaces, the mold surfaces corresponding to a configuration of the article to be molded, an amount of the plastic sheet communicated to the first mold assembly being sufficient to form a skin of the article; applying a vacuum to one side of the first mold assembly while concurrently applying pressurized gas to an opposing side of the first mold assembly so as to force said heated plastic sheet into conformity with the mold surfaces; cooling the conformed plastic sheet; transferring the conformed plastic sheet to a second mold assembly; introducing to the conformed plastic sheet a reinforced plastic melt made from material identical or different from that of the plastic sheet, said plastic melt having a blowing agent to achieve volume expansion and the production of a cellular reticulate structure; cooling said plastic melt to form a solidified plastic member adhered to said conformed plastic sheet, said conformed plastic sheet and said adhered solidified plastic member together comprising said article; and removing said article from said second mold assembly.
