Carbon fiber is not as durable as aluminum. Carbon fiber is unpredictable, as analysis and failure results are not as controlled as they are in the case of aluminum. Carbon fiber shatters, and may crack or chip. Aluminum versus carbon fiber is cheaper, but carbon fiber is tensile and not ductile.
Strength. It's also important to compare the strength of two materials which have the same thickness. Aluminum has a strength of about 500 kilonewtons compared to carbon fiber which can have up to 1600 kilonewtons of strength.
Carbon nanotubes will. The carbon nanotube's superior atomic-bonded crystal structure is what makes it the strongest, stiffest material known to man and nearly 20 times stronger per pound than carbon fiber.
Carbon fiber is five-times stronger than steel and twice as stiff. Though carbon fiber is stronger and stiffer than steel, it is lighter than steel, making it the ideal manufacturing material for many parts. Carbon fiber is made of thin, strong crystalline filaments of carbon that is used to strengthen material.
We say “carbon fiber,” but what we really mean is “carbon-fiber composite”—it's not the only material in your frame. That's because carbon fiber's incredible stiffness properties come at a price: On its own, it is quite brittle and prone to splitting and cracking.
Carbon fiber bikes will not break easily due to the strong materials that are used to make them. So, carbon can definitely be used to make a highly durable bike frame that will not break easily.
When carbon fiber is made, the tightly packed material is resistant to breaking due to its bonded structure. This makes the material strong despite its light weight.
Strength, Stiffness, and Comparisons With Other Materials The modulus of carbon fiber is typically 33 msi (228 GPa) and its ultimate tensile strength is typically 500 ksi (3.5 Gpa).
When carbon fiber is made, the tightly packed material is resistant to breaking due to its bonded structure. This makes the material strong despite its light weight.
Their graphene infused carbon fiber had 225% greater strength and 184% greater stiffness than conventionally made PAN-based carbon fibers. Their analysis revealed that it was because the flat structure of graphene helps to align PAN molecules consistently throughout the strands.
Kevlar is a synthetic fiber that is in the aramid fiber's group which is heat resistant. Kevlar fiber has a tensile strength comparable with that of carbon fiber, a modulus between those of glass and carbon fibers and lower density than both.
Carbon fiber dust is well-known to be hazardous to electronics because carbon fibers are electrically conductive. If allowed to build up, this dust can short out computers and cause other digital device havoc. It's also associated with lung damage in people.
Carbon fiber is very strong when stretched or bent, but weak when compressed or exposed to high shock (e.g. a carbon fiber bar is extremely difficult to bend, but will crack easily if hit with a hammer).
Most manufacturers agree that the lifespan of a carbon fiber frame is 7 to 10 years. Much less for high end frames. All carbon fiber parts go through an aging process called degassing.
Carbon composite based on epoxy resin shows a very long lifetime during fatigue testing, thus there's no degradation of the composite over the lifetime of a bike. Only long-term strong UV exposition can harm the epoxy structure, but all our frames have a UV protective agent included in the final paint layer.
Kevlar is a synthetic fiber that is in the aramid fiber's group which is heat resistant. Kevlar fiber has a tensile strength comparable with that of carbon fiber, a modulus between those of glass and carbon fibers and lower density than both.

A new form of carbon, dubbed carbyne, is stronger and stiffer than any known material. In fact, carbyne is about two times stronger than graphene and carbon nanotubes, which until now were the strongest materials by some margin.
carbyneResearchers from Rice University have calculated the properties of a little-studied form of carbon known as carbyne, and they've determined that it should have a "specific strength surpassing that of any other known material." That includes graphene — the longstanding titleholder for strongest material — which the
Strength. Though either material is substantially stronger than steel, industrial carbon fiber is more than 20 percent stronger than the best fiberglass. Carbon fiber boasts a strength to weight ratio roughly twice that of fiberglass.
Carbon fiber is not used to protect against bullets. Carbon have poor impact properties and are very brittle. Their use in structural applications requires them to be surrounded by resins, which means that they could not be used in bulletproof vests.
As a comparison, steel has a tensile modulus of about 29 million psi (200 million kPa). Thus, the strongest carbon fibers are ten times stronger than steel and eight times that of aluminum, not to mention much lighter than both materials, 5 and 1.5 times respectively.
Carbon fiber is not used to protect against bullets. Carbon have poor impact properties and are very brittle. Their use in structural applications requires them to be surrounded by resins, which means that they could not be used in bulletproof vests.
Carbon fiber has less than half the density of titanium. Carbon fiber has a high strength-to-weight ratio but it isn't quite as strong as titanium. Because carbon fiber is so much less dense, more material can be used to create enough strength while still maintaining a light weight.
Will Sunlight Weaken Carbon Fibers? Even though the carbon fibers themselves are not susceptible to UV damage, the resin used to bond carbon fibers together can be, meaning that your carbon fiber parts or frames could degrade over time, "in theory".
But when made incorrectly, carbon-fiber components can easily break. The parts are built by layering fibrous carbon that's bound together with resin. If the manufacturer skimps on the resin or simply applies it unevenly, gaps can form, making it susceptible to cracks.
While carbon fibre offers the best strength and rigidity to weight in the industry, it is also generally the most expensive of reinforcements. That said, Kevlar offers a better abrasive strength than carbon fibre, which is why it commonly associated with bulletproof vests.
Why hasn't there been a proliferation of carbon fiber in the construction of cars? It's a different process from steel and aluminium, and a very expensive and time consuming one resulting in over 10 times the cost even accounting for advancements in manufacturing.
Carbon fibers are classified by the tensile modulus of the fiber. Thus, the strongest carbon fibers are ten times stronger than steel and eight times that of aluminum, not to mention much lighter than both materials, 5 and 1.5 times respectively.

Kevlar. Perhaps one of the better-known bulletproof materials, Kevlar is a synthetic fiber that's heat resistant and incredibly strong. It's also lightweight, making it a popular choice for wearable bulletproof items. Kevlar is used in both military and civilian applications.
