Carbon fiber reinforced polyamide composite material pre-infiltrated basalt fiber cloth and preparation method thereof

Abstract

The invention discloses carbon fiber reinforced polyamide composite material pre-infiltrated basalt fiber cloth and a preparation method thereof. The preparation method includes the steps that basaltfiber cloth base cloth is subjected to carbon fiber reinforced polyamide composite material pre-infiltration and then subjected to rolling traction, and the basalt fiber cloth is obtained; the carbonfiber reinforced polyamide composite material is prepared from the following raw materials: PA66, PA6, chopped carbon fibers, a toughening agent, a compatilizer, a filling modifier, an antioxidant, alubricating agent and a dispersing agent. The carbon fiber reinforced polyamide composite material is used for replacing traditional thermosetting resin pre-infiltrated basalt fiber cloth, the production cost is reduced, the forming period is shortened, and the carbon fiber reinforced polyamide composite material can be recycled; the chopped carbon fibers play a riveting role between the fiber cloth and the polyamide resin, so that the interlayer strength is improved. The basalt fiber cloth is higher than glass fiber cloth in strength and far lower than carbon fiber cloth in price, and is a novel inorganic material with high cost performance.

Description

technical field [0001] The invention belongs to the field of carbon fiber reinforced thermoplastic composite materials, in particular to a carbon fiber reinforced polyamide composite material pre-soaked basalt fiber cloth and a preparation method thereof. Background technique [0002] With the lightweight of automotive products and the development of lightweight, portable and high-strength electronic products, thermosetting polymer pre-impregnated carbon fiber composite materials and some thermoplastic polymer pre-impregnated carbon fiber composite materials have developed rapidly. Lightweight technology has become an important way for new energy vehicles to achieve energy saving and emission reduction and improve battery life. Carbon fiber composite materials are an important basic material for lightweight vehicles. At present, the carbon fiber composite materials used in the automotive industry are mainly carbon fiber reinforced thermosetting resin composite materials, and...

AI Technical Summary

Problems solved by technology

At present, there are two major defects in thermoplastic pre-impregnated carbon fiber cloth that need to be improved: (1) thermoplastic pre-impregnated carbon fiber cloth is not fully infiltrated, the surface of the fiber cloth is easily damaged, and the impregnated layer is easy to fall off; (2) thermoplastic pre-impregnated carbon fiber cloth is due to the high market price of carbon fiber , so that it has no lower cost advantage in application
