Embodiment 1

[0016] Embodiment 1, the present invention discloses a fiber-reinforced MC nylon composite material, including the following raw materials in weight percentage: 10%-90% of caprolactam monomer, 10%-75% of reinforcing fiber, 0.2%-0.4% of catalyst, co-catalyst 2%-5%, the above weight percent caprolactam monomer, reinforcing fiber, catalyst and co-catalyst are mixed into a liquid active material and then molded. The caprolactam monomer is C6H11NO, and the reinforcing fiber is natural fiber or chemical fiber.

Embodiment 2

[0017] Embodiment 2: The weight percent of the caprolactam monomer described in this embodiment is 35%, the reinforcing fiber is 61.7%, the catalyst is 0.3%, and the co-catalyst is 3%.

Embodiment 3

[0018] Embodiment 3: The caprolactam monomer described in this embodiment is 40%, the reinforcing fiber is 53.8%, the catalyst is 0.2%, and the co-catalyst is 6%.

[0019] The composite material uses caprolactam monomer as the resin matrix, and reinforcing fibers as the reinforcing skeleton. The low viscosity and good fluidity of the caprolactam solution are used to ensure the infiltration of the caprolactam on the fibers, greatly increasing the fiber content of the product, and having high physical and mechanical properties.

[0020] The invention also discloses a molding method of fiber-reinforced MC nylon composite material, which is characterized in that: take caprolactam monomer, reinforcing fiber, catalyst and co-catalyst according to the above weight percentage, melt the caprolactam monomer and add catalyst to mix, and mix The material is vacuum dehydrated under the condition of -0.1MPa for 1-20min. After the dehydration is completed, a co-catalyst is added to the mixtur...

Abstract

The invention discloses a fiber reinforced MC nylon composite material and a moulding method thereof. The composite material employs a caprolactam monomer as a resin matrix and takes reinforced fibers as a reinforced frame, the characteristics of low viscosity and good fluidity of a caprolactam solution are used, infiltration of fiber by caprolactam can be ensured, fiber content of a product is greatly increased, and the composite material has strong physical and mechanical properties. The moulding method can be used for preparing a liquid state active material to be polymerized through a base catalysis principle, a cocatalyst is added and is casted into a preheated die, then the step of hot press molding is carried out, the physical and mechanical properties such as tensile strength and bending strength of the prepared composite material is better than that of the MC nylon, the impact intensity is obviously increased, heat resistance and size stability are good, flame resistance performance is enhanced, and original characteristics of good wear resistance and self lubricating of the MC nylon can be kept, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of reinforced plates or reinforced components, in particular to a fiber-reinforced MC nylon composite material and a forming method thereof. Background technique [0002] MC nylon is a kind of engineering plastic, which has many unique properties such as light weight, self-lubricating, wear-resistant, anti-corrosion, and insulation. It is a widely used engineering plastic. However, its strength, heat resistance, and dimensional stability cannot meet higher-level requirements. With the development of modern science and technology and practical applications, higher requirements are put forward for MC nylon materials. Caprolactam monomer is the main raw material for preparing MC nylon, which is characterized by low viscosity and good fluidity. It is prepared into a liquid state through the principle of alkali catalysis. The active material is injected into the preheated mold to fully infiltrate the reinforcin...
