Thermoforming of Products from Consolidated Sheet Blanks Based on the Polypropylene Reinforced by the Fiberglass
摘要
Abstract
The paper presents a technology for the out-of-autoclave consolidation of thermoplastic composite material based on the polypropylene and fiberglass. The temperature-time regimes of consolidation and thermoforming were optimized using the differential scanning calorimetry and rheometry methods. A technique for carrying out the vacuum-thermal consolidation and press molding is described making it possible to obtain consolidated plates, which are blanks for thermoforming.
