PLA materials

Polylactic acid (PLA), also known as polypropyleneglycolate, raw materials from corn, potatoes and other starch-containing food crops or crop straw cellulose, by modern biological fermentation technology to produce high-purity small molecules of lactic acid contained in the human body, and then the lactic acid prepared into a cyclic dimer propyleneglycolate, and then the propyleneglycolate ring-opening polymerization to produce polylactic acid and then after a special polymerization reaction The lactic acid is then prepared into a cyclic dimer, which is then ring-opened and polymerized to produce polylactic acid. Because of its reliable biosafety, biodegradability, environmental friendliness, good mechanical properties and easy processing, PLA has a broad application prospect in biomedical polymers, textile industry, plastic industry, furniture industry, agricultural land film and packaging industry, etc. The raw materials of PLA are sufficient and renewable, and the products made from it can be composted directly after use, and eventually can be completely degraded to CO2 and H2O. PLA is an environmentally friendly, green and sustainable polymer material.

PLA-LCF materials

Long carbon fiber reinforced composites offer significant weight savings and provide optimum strength and stiffness properties in reinforced thermoplastics. The excellent mechanical properties of long carbon fiber reinforced composites make it an ideal replacement for metals. Combined with the design and manufacturing advantages of injection molded thermoplastics, long carbon fiber composites simplify the re-imagining of components and equipment with demanding performance requirements. It's widespread use in aerospace and other advanced industries makes it a "high-tech" perception of consumers.

LCF & SCF

Long carbon fiber and short carbon fiber mainly refer to the application length of carbon fiber materials, there is no strict fixed distinction between the two, generally between a few millimeters to a few centimeters, the more common specifications are 6mm, 12mm, 20mm, 30mm, 50mm. the shorter the length the easier it is to uniformly and non-directionally distributed in the resin matrix. Therefore, the mechanical properties of short carbon fibers are far less than those of long carbon fiber reinforced thermoplastic composites.

Q & A

1. How does thermoplastic carbon fiber composite material achieve low cost and environmental protection?

Thermoplastic carbon fiber composites are used to make parts for high-end machinery. They have excellent machinability, vacuum forming, stamping mold plasticity, and bending processability.

For example, Teijin has been able to add a recycling process to the process according to special needs, and to shred and mold the corners of thermoplastic carbon fiber composites after stamping to make recycled materials for making small products or for molding nuts and studs on carbon fiber prototypes. This method can greatly reduce the loss of raw materials, improve the efficiency of the use of thermoplastic carbon fiber composite materials, reduce the overall cost, and thus achieve the purpose of environmental protection.

Thermoplastic carbon fiber products production process
In addition, compared with thermoset carbon fiber composites, thermoplastic carbon fiber composites can shorten the molding cycle time due to its special process characteristics, which can further reduce the production cost in terms of production efficiency.


2. Is thermoplastic carbon fiber composite material only suitable for injection molding?

From the process point of view, injection molding has a higher degree of automation compared with molding, and the raw material is not in contact with the outside world, so the product appearance quality is guaranteed, and there are no black spots, impurities, uneven colors, etc. The mechanical properties, dimensional stability and precision of the product are relatively higher. At present, Japan Toray, these carbon fiber giants in the application of carbon fiber reinforced thermoplastic composites, the main use of injection molding method, and this method is suitable for the production of complex-shaped parts and mass production. It should be noted, however, that thermoplastic carbon fiber composites using injection molding must be reinforced with short-cut or powdered carbon fibers, and this process is not applicable to continuous carbon fiber reinforced thermoplastic composites.

Compared to injection molding equipment, compression molding equipment and its mold structure are relatively simple and less expensive to manufacture. The molding equipment can be used for both thermosetting and thermoplastic resins, and in the molding of thermoplastic carbon fiber products, it is the full experience of manufacturing thermosetting carbon fiber parts. The use of molding to make thermoplastic carbon fiber composite parts, the loss of raw materials is smaller and will not cause excessive losses, and when applied to mass production, the price is better to meet the market demand compared to the injection molding process.
