Can thermoset and thermoplastic carbon fibers be distinguish

Can thermoset and thermoplastic carbon fibers be distinguished by appearance alone? Carbon fiber has been developed in China for at least 30 years, but the early development rate is slow, almost stagnant, and has been tilted by national policies for nearly 20 years, and has embarked on the road of accelerated development. Although domestic carbon fiber is at least 20 years away from the world's advanced level, the basic demand can already be met. Foreign carbon fiber leaders have been studying the preparation and application of thermoplastic carbon fiber, and in this regard, we are also trying to achieve technological breakthroughs and industrial scale expansion, or unknown.
 
 
Can thermoset and thermoplastic carbon fibers be distinguished by appearance alone?
 
At present, the market is still based on thermosetting carbon fiber, after all, the preparation difficulty is relatively low on a lot, with the existing technology and equipment level, you can prepare thermosetting carbon fiber in large quantities, but want to break the capacity ceiling, the preparation of carbon fiber itself needs to expand production capacity.
 
Thermosetting and thermoplastic carbon fibers are two important branches in the carbon fiber family, one represents the present and one represents the future. Thermosetting and thermoplastic carbon fibers have similar mechanical properties and almost the same appearance, so how to distinguish between industrial production and the production of carbon fiber parts?
 
In fact, from the appearance of the light, the naked eye can not distinguish between thermosetting and thermoplastic carbon fiber, although the resin contained in it is different, but the same black, regardless of whether there is a grain, can not be effectively distinguished. So how do you tell the difference between thermoset carbon fiber and thermoplastic carbon fiber? Perhaps only rely on the product description and ingredient identification to tell the difference.
 
Can thermoset and thermoplastic carbon fibers be distinguished by appearance alone?
 
What is the difference between thermosetting and thermoplastic carbon fiber in performance?
 
Since the appearance of thermosetting and thermoplastic carbon fiber is the same, the mechanical performance is also between the middle, then why say that one represents the present and one represents the future? The fundamental reason is that thermoplastic carbon fiber has the characteristics of repeatable processing, do not underestimate this characteristic, it may subvert the current processing process of carbon fiber products, but also change the dilemma that carbon fiber products are difficult to recycle.
 
1, mechanical properties: thermosetting and thermoplastic carbon fiber composites can show excellent mechanical properties, including high strength and stiffness. Specific performance characteristics may vary depending on fiber type, resin formulation, and composite structure. In general, thermoset composites tend to have higher heat resistance and better resistance to creep deformation, while thermoplastic composites may have excellent impact resistance and toughness.
 
2, repeated processing characteristics: thermosetting composites usually require a curing process, involving increased temperature and pressure, to achieve their final properties. Once cured, thermosetting resins become hard and non-melting. In contrast, thermoplastic composites can be heated and reformed multiple times due to the reversible melting and solidification properties of thermoplastic resins.
 
3, recyclability: One of the advantages of thermoplastic composites is their recycling potential. Since thermoplastic resins can be melted and reprocessed multiple times without significant loss of performance, thermoplastic carbon fiber composites can be recycled and reused. In contrast, thermosetting composites are generally more difficult to recycle due to their irreversible curing process.
 
In the future, the problems that hinder the preparation of thermoplastic carbon fiber will be eliminated one by one, and the batch preparation of thermoplastic carbon fiber prepreg will become a reality, but thermoset carbon fiber will not be completely replaced by thermoplastic carbon fiber, and the two carbon fiber composites may continue to glow and heat in different scenarios.
