Text/Polymer

The advent of 5G communication network is a new science and technology, which also opens up new opportunities for development of polymer materials. High-performance material suppliers are actively preparing materials needed for 5G communication. Among them, long fiber reinforced LFT composite materials can be used in 5G base station radomes, equipment frames, brackets, filters, etc. Today, we will talk about LFT materials.

5G Communication Materials - LFT-PP Long Fiber Reinforced Plastic Composite

1. Definition and characteristics of LFT-PP

Long Fiber Reinforced Thermoplastics (abbreviated as LFT) are long, continuous glass fibers that are completely impregnated with resin through a special process into long strips and then cut into pieces of a specific size. Colloidal particles or long strips of resin-impregnated coated fiberglass directly after molding or injection molding. The length of fiberglass in LFT material is typically greater than 3 mm, and its application development goal is to be used as a semi-structural and structural material.

Among them, PP-based LFT composite material has advantages of light weight and high strength, easy production and cost optimization. As it is a new high performance engineering plastic, its application range is getting wider and wider. Wider. It is currently first choice for polymer-based composite materials used in a light vehicle.

2. LFT-PP Preparation Process

According to preparation process, LFT-PP high performance composite materials can be divided into two categories: LFT-G process and LFT-D-ILC process.

2.1 LFT-G process

Firstly, LFT-G long fiber rubber particles are made by mixing resin, fiberglass, additives, etc. through a special melt impregnation method, and then final product is made by injection molding.

Due to different processing technology, LFT fiber length is also different. The impact properties are especially dependent on length of glass fibers. Commercial LFT-G colloids are typically 6-25 mm long. LFT-G composites support design of semi-structural automotive applications such as front end components, door components, tool holders, rear doors and seating systems by combining light weight and functional focus.

2.2 FT-D-ILC Process

LFT-D-ILC is an online molding technology for long fiber reinforced thermoplastics. provides moderate mixing in accordance with requirements for mechanical characteristics of part. In recent years, LFT-D-ILC processing technology has become most popular processing technology for LFT products, as shown in Fig. 2-1.

3. Application of LFT-PP

Automotive field: LFT-PP materials can not only effectively improve rigidity, toughness, creep resistance and dimensional stability of finished products, but also reduce production cost of automotive modules, shorten molding cycle, and prepare complex and complex automotive modules.

5G scope: modified LFT materials can be used in 5G base stations; mobile phones can be used in mobile phone cases, back covers, batteries, chips and other components.
