Carbon fibre has several advantages over plastics, including a high strength-to-weight ratio, excellent durability, and the ability to be tailored to specific performance properties. Plastic on the other hand, is more cost-effective, is easier to manufacture, and is available in a variety of types that may offer suitable performance for your needs. The budget of your project may play a role in determining whether carbon fibre is the right choice. See our post, How Much Does Carbon Fibre Cost? Factors That Affect the Price, for information on the cost of carbon fibre.

Materials that are highly susceptible to work hardening and strain hardening during machining are typically those with a high degree of ductility.

Do you have an idea for an innovative product but aren’t quite sure how to bring the idea to life? The process of taking your idea from a sketch on paper to a completed project is multiphasic, and there are many important factors you’ll need to consider along the way. One of the most important decisions you’ll need to make for any project is what the final product will be made from though, choosing a material type isn’t always simple. The unique properties of a given material, including its weight, will need to be considered during the manufacturing process. So, how can you know what material is right for you?

Work hardening, also known as strain hardening, is a metallurgical phenomenon observed in metals. It leads to an increase in hardness and strength due to plastic deformation below the recrystallization range. This process is primarily induced by mechanical stress, including machining and forming, causing structural changes in the material.

The choice between carbon fibre and plastics is largely dependent on the specific application and performance requirements of the product. Each material has its advantages and drawbacks, and it’s essential to consider their properties when determining which material is right for your needs.

Strainhardening

Increased Hardness and Strength: Work hardening increases the material's hardness and strength by reconfiguring its atomic structure, hindering further deformation. Selective Metal Susceptibility: Certain metals, such as soft, low-carbon steel, alloys containing nickel and manganese, and specific superalloys like Inconel and Monel, exhibit notable work hardening traits. Plastic Deformation as Trigger: Plastic deformation, caused by various techniques such as bending, rolling, or hammering, is the primary driver of work hardening.

Carbon fibre is generally lighter than most plastics while also being much stronger. Carbon fibre is a high-performance material, and its specific strength and stiffness are considerably higher than most types of plastics. Carbon fibre is ideal for applications where weight reduction is important, such as aerospace, automotive, and sporting goods industries though plastic can also be valuable in these applications.

Understanding the nuances of work hardening aids in developing effective manufacturing strategies and maintaining the desired mechanical properties of materials.

It’s important to note that there are different types of plastics available, all with varying densities. When considering the weight difference between carbon fibre and plastic, you’ll need to consider the type of plastic to make an accurate comparison.

Aluminium Alloys: Many aluminium alloys, such as 2024 and 7075, are highly susceptible to work hardening, requiring careful tool selection and cutting techniques. Copper and Copper Alloys: Pure copper, brass, and bronze are known for their high ductility and can 'work harden' rapidly during machining. Titanium Alloys: Titanium alloys, common in aerospace and medical applications, exhibit strong work hardening tendencies, necessitating caution during machining. Stainless Steels: Austenitic stainless steels like 304 and 316 are susceptible to work hardening. Proper tooling and cutting speeds are crucial when machining them. Nickel-Based Superalloys: Superalloys such as Inconel and Monel, used in aerospace and marine applications, are highly susceptible to work hardening. Brass and Lead: Copper-zinc alloy (brass) and soft metals like lead 'work harden' easily during machining. Certain Plastics: Thermoplastic materials like polycarbonate can exhibit strain hardening under mechanical stress during machining.

It's important to consider cutting parameters, tool selection, and lubrication to minimize work hardening and strain hardening effects during machining. Also, post-machining processes like annealing can relieve the hardening effects and restore the material's original properties when necessary.

Distinguishing from Recrystallization: Work hardening is distinct from hot working as it occurs at temperatures below the recrystallization range. Hot working involves deformation at high temperatures, preventing strain hardening. Reversibility through Heat Treatment: Despite its transformative effects, work hardening isn't a permanent change. Heat treatment processes like annealing can restore the material's initial properties.
