Previous answer claimed it was molding that is difficult but that is the least of its problems, when done by professionals the molding problem is no problem at all. However the first reason the previous answer claimed was very true indeed.
Carbon Fiber is nowadays extremely expensive, a good example of this is you hardly see any cars released with carbon fiber these days that don't cost you at least 100,000.
Apart from expenses recycling is very difficult when it comes to carbon, you cannot melt it like steel to reuse, its recycling process is way more complicated and tedious, and to top that the recycled carbon is too weak to be used on manufacturing another vehicle, so this would result in too much waste.
Also another difficulty i personally had with carbon fiber is its repair. once a carbon fiber structure is dented or cracked you cannot beat it back into shape like steel or add a fiber glass layer like panel beaters do. once that dint or crack has occurred the entire structure's modulus and tensile strength and other factors are flawed and the part would need to be thrown away and replaced.
There may be more disadvantages to carbon fibre manufacturing but these are the three i have personally experienced and faced. i hope that was thorough enough without being tedious.

One possible use for carbon nanotubes is in advanced materials for building strong and lightweight structures, such as in aerospace and construction. They could also be used in electronics for high-performance electrical applications due to their excellent conductivity.
The term "nano" in carbon nanotubes refers to their extremely small size, typically on the nanometer scale (1 to 100 nanometers in diameter). This nanostructure gives carbon nanotubes unique properties, such as exceptional strength, lightweight, and electrical conductivity. Their small size also allows them to exhibit quantum mechanical effects, making them valuable in various applications, including nanotechnology, electronics, and materials science.
A carbon nanotube can be compared to the fullerenes, a group of spherical carbon allotropes (allotropes are different forms of a single element).The key difference is that the fullerenes are spherical in shape whereas carbon nanotubes resemble a fullerene network that has been stretched into a cylindrical shape. Furthermore, nanotubes contain more carbon atoms than most fullerenes do.
The concept of carbon nanotubes was first proposed by Sumio Iijima in 1991, when he observed cylindrical carbon molecules in soot particles.
Carbon remain carbon.

Bucky paper, composed of carbon nanotubes, has several disadvantages, including high production costs and challenges in scalability for commercial applications. Its mechanical properties can vary depending on the alignment and density of the nanotubes, potentially leading to inconsistent performance. Additionally, concerns regarding the environmental impact and potential toxicity of carbon nanotubes raise safety questions in their use. Finally, integrating bucky paper with existing materials and technologies can be complex, limiting its widespread adoption.

Although there are numerous instances of people observing carbon nanotubes, most literature credits Sumio Iijima as the discoverer of carbon nanotubes.
the structure of nanotubes are carbon atoms joint together covalently to form a long tube.
No. Paper is cellulose, a carbohydrate usually derived from plant material. Carbon nanotubes are a variant of pure carbon that are used in a variety of high-strength materials.
Nanotubes are typically made from carbon atoms arranged in a cylindrical structure. Carbon nanotubes can have different properties depending on their structure and can be single-walled or multi-walled. They are known for their strength, flexibility, and thermal conductivity.
carbon nanotubes
Strength:Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively.Hardness:Standard single-walled carbon nanotubes can withstand a pressure up to 25 GPa without deformation.
This technology is being explored as an option for body armor, but there are no body armor products using carbon nanotubes as yet.
