Problems solved by technology

[0002] Thermoplastic FRP is divided into short fiber reinforced thermoplastics (SFT) and glass fiber mat reinforced thermoplastics (GMT). SFT has good fluidity due to its short fibers. It is mainly used in injection molding and compression molding processes to produce products with complex shapes, but Low strength, can only be used for non-structural parts

Abstract

The invention relates to a processing method of a glass fiber short-cutting needled felt. The method comprises the following steps that thermoplastic resin in a flowing state is poured on a glass fiber needled felt, and the thermoplastic resin fully mixed and soaked the glass fiber needled felt; and the glass fiber needled felt is the short-cutting needled felt for GMT, and the thickness is 10-15cm. The processing method of the glass fiber short-cutting needled felt method has the advantages that the short-cutting needled felt for the GMT is developed, and the product single weight is uniform;and through repeated tests, a produced product can meet requirement of different clients and different glass fiber reinforced plastic products on the needled felt, the requirement of the glass fiberreinforced plastic production process for fluidity and expansion height is met, and meanwhile, the requirement for strength of the product is met.

Description

technical field [0001] The invention relates to a processing method of glass fiber chopped needle-punched felt, which belongs to the processing method of glass fiber chopped needle-punched felt products, and relates to a reinforced base material for producing thermoplastic glass fiber reinforced plastics. Background technique [0002] Thermoplastic FRP is divided into short fiber reinforced thermoplastics (SFT) and glass fiber mat reinforced thermoplastics (GMT). SFT has good fluidity due to its short fibers. It is mainly used in injection molding and compression molding processes to produce products with complex shapes, but It has low strength and can only be used for non-structural parts. [0003] Therefore, the development of a long-fiber felt can greatly improve the specific strength, toughness and impact resistance of thermoplastic FRP by making the fibers entangled with each other through the needle punching process. Applying thermoplastic FRP to structural parts with...
