Abstract

The invention discloses a polyaryletherketone resin-based suspension sizing agent for carbon fibers and a preparation method thereof. The suspension sizing agent is composed of a polyaryletherketone resin, a dispersant, a stabilizer and deionized water. The suspension sizing agent has stable properties and can be used for preparing carbon fibers. The prepared sizing carbon fibers are suitable forintermediates such as carbon fiber fabrics and prepregs for polyaryletherketone resin-based composite materials, and have good processing performances and interface binding ability.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber sizing agents, in particular to a polyaryletherketone resin-based suspension type sizing agent and a preparation method thereof. Background technique [0002] Composite materials are materials with new properties composed of two or more materials with different properties through physical or chemical methods. Due to its high strength, high modulus, and high temperature resistant new fiber material, carbon fiber is currently one of the most commonly used composite reinforcement phases. The polyaryletherketone resin contains rigid benzene rings in its molecular structure, and has outstanding high-temperature performance, excellent mechanical properties, electrical insulation, and processability, and is an important high-temperature-resistant composite matrix resin. Due to their respective excellent properties, carbon fiber reinforced polyaryletherketone resin-based composites are widely used i...
