LFT-G PPS Polyphenylene sulfide with long carbon fiber thermoplastic resin high rigidity and strength

PPS Information

Polyphenylene sulfide (PPS) is not enhanced before modification, its disadvantages are brittle, poor toughness, low impact strength, after filling glass fiber, carbon fiber and other enhancements modified to overcome the above shortcomings, to obtain very good overall performance.

PPS filling Long carbon fiber

In the modified engineering plastics industry, long fiber reinforced composites are composites made from long carbon fibers, long glass fibers and polymer matrix through a series of special modification methods.

The most important feature of long fiber composites is that they have superior performance that the original materials do not have. If we classify them according to the length of the reinforcing materials added, they can be divided into: long fiber, short fiber and continuous fiber composites.

Long carbon fiber composites are one kind of long fiber reinforced composites, which are a new fiber material with high strength and high modulus. It is a new material with excellent mechanical properties and many special functions.

Corrosion resistance: LCF carbon fiber composite materials have good corrosion resistance and can adapt to the harsh working environment.

UV resistance: the ability to resist UV is strong, and the products are less damaged by UV.

Abrasion and impact resistance: the advantage of comparing with general materials is more obvious.

Low density: lower density than many metal materials, can achieve the purpose of light weight.

Other properties: such as reducing warpage, improving rigidity, impact modification, increasing toughness, electrical conductivity, etc.

LCF carbon fiber composites have higher strength, higher rigidity, lower weight, and excellent electrical conductivity compared with glass fiber.

Q&A

1. Are carbon fiber composite products very expensive?

The price of carbon fiber composite products is closely related to the price of raw materials, the level of technology and the number of products. The higher the performance of the raw material, the more expensive it is, such as the carbon fiber PEEK thermoplastic material used in orthopedics. Of course, the more complex the manufacturing process, the greater the working time and workload, and the increased production costs. However, the larger the order quantity, the lower the cost per product. In the long run, the superior performance of carbon fiber will extend the life of the product, reduce the number of maintenance, and is also very beneficial to reduce the cost of use.

2. Are carbon fiber composite products toxic?

Carbon fiber composites are made of carbon fiber filaments mixed with ceramics, resins, metals and other substrates, and are generally not toxic. For example, the above-mentioned PEEK material is made of food-grade resin, which is very compatible with the human body and is not only harmless to humans, but also becomes a more ideal material for orthopedic surgery because of its high strength and elastic modulus close to the bone cortex. Carbon fiber medical bed plate, will be in daily contact with many patients body, will not have adverse effects on the human body, on the contrary, for the accuracy of medical diagnosis and a great help.

3. What is the difference between thermosetting carbon fiber composites and thermoplastic carbon fiber composites?

Thermoset carbon fiber composites favor the role of curing agent in curing and molding. While thermoplastic carbon fiber composite products mainly rely on cooling down to achieve the shaping. Thermoplastic carbon fiber composites are not as popular as thermoset carbon fiber composites, mainly because they are expensive and are generally used in high-end industries. Thermoset carbon fiber composites are difficult to recycle due to the limitation of the resin matrix itself, and are generally not considered; thermoplastic carbon fiber composites can be recycled, and can be made twice as long as they are heated to a certain temperature.
