30% Carbon Fiber Reinforced Polypropylene

Carbon fiber reinforced polypropylene introuduction

Polypropylene is a polymer material with low cost, excellent performance and wide range of uses. Through carbon fiber reinforcement, the strength, heat distortion temperature and dimensional stability of thecarbon fiber reinforced resin polypropylene material can be improved. Carbon fiber reinforced polypropylene is made of carbonized fiber treated with epoxy coating and graphite woven. We mix the polypropylene resin, toughening agent, antioxidant, compatibilizer, lubricant, light stabilizer and modified fiber evenly, put it into a flat vulcanizer, heat it up to 140°C, and keep it warm for 1 hour under a pressure of 12MPa. Raise the temperature to 240°C, keep it warm for 1 hour, then cool it to 90°C and release the pressure. After taking it out, cool it to room temperature to form the carbon fiber reinforced polypropylene. Its advantages are light weight, high tensile strength, solidity, high strength, low density, good dimensional stability, creep resistance, heat resistance, grease resistance, and good lubricity.

Carbon fiber reinforced polypropylene applications

Carbon fiber reinforced polypropylene can be used in automobiles, electronics, medical and other fields. In the automotive field, with the development of new energy vehicles and the trend of lightweight vehicles, carbon fiber reinforced resins are increasingly used in the automotive field. The lower density meets the needs of lightweight vehicles and can be used to make extremely light components, safely replacing aluminum and magnesium without losing steel and strength, and being electrically conductive. The material can be used to produce automotive structural components such as car bodies, chassis and powertrains. Carbon fiber reinforced polypropylene materials have high mechanical properties and can be used in automotive parts such as automotive auxiliary instrument assemblies. In the electronics field, arbon fiber reinforced polypropylene materials are used in high-strength, light-weight electronic equipment casings, circuit board brackets, and radiators. It has good thermal conductivity. It can manufacture parts with high precision requirements to meet the needs of electronic equipment. In the medical field, carbon fiber reinforced polypropylene materials have a series of advantages such as light weight, high modulus, high specific strength, low thermal expansion coefficient, high temperature resistance, thermal shock resistance, corrosion resistance, and good vibration absorption.

Carbon fiber reinforced plastic injection and extrusion molding

Injection molding and extrusion molding of carbon fiber reinforced plastic are two common processing methods.Injection molding is to heat and melt the carbon fiber reinforced plastic, then inject it into the mold through an injection molding machine, and then cool and shape it to obtain the product. Advantages of this process include:

1. Can manufacture products with complex shapes.
2. Able to achieve high-precision molding.
3. High production efficiency.

Extrusion molding is to heat and melt the raw materials in an extruder, and then extrude them through a die. Mainly used for 3D printing filaments. Its characteristics are:

1. Suitable for continuous production.
2. Can produce products with larger cross-sections.
3. The cost is relatively low.

When processing carbon fiber reinforced plastic injection molding and extrusion molding, you need to pay attention to the following points:

1. Strictly control the processing temperature to ensure the performance of the material.
2. Select the appropriate mold and extruder.
3. Pay attention to the dryness of carbon fiber reinforced plastics to avoid moisture affecting product quality.
4. Reasonably design the product structure to give full play to the performance of the material.
