CFRP or Carbon Fiber Reinforced Plastics (Carbon FRP)

CFRP is the material of choice for engineers looking for opportunities to improve their design or process. Alformet applies UD-tape made from a thermoplastic matrix reinforced with continuous carbon fibers (CFR-TP), that offer high strength and stiffness while reducing weight of the component. The durability of the material through its resistance against corrosion and chemicals, allows you to reduce maintenance and increase life cycle time. Combined with 100% recyclability, CFRP with thermoplastic resin offers the best of two worlds: metals and plastics.

Find out why engineers across the globe are improving products and processes with CFR-TP, saving costs while achieving sustainability targets!

What properties does CFRP (Carbon Fiber Reinforced thermoPlastics) have?

Alformet processes UD-tape from thermoplastics reinforced with carbon fibers. The most valuable properties are:

Lightweight (4 times lower than steel and 30% lower than aluminium)
High strength and high stiffness
Corrosion and chemical resistant (reduced maintenance)
Excellent impact energy absorption and damping properties
High fatigue resistance
High temperature formable: Suited for bending and reshaping
100 % recyclability

What are the different variations of CFRP with thermoplastic resin?

Virtually any combination of thermoplastic resin with carbon fibers can be processed at Alformet. The most used combinations of carbon fiber and thermoplastic resin are:

PP-CF (polypropylene with carbon fiber)
PA6-CF (polyamid6 with carbon fiber)
PC-CF (polycarbonate with carbon fiber)
PEEK-CF (polyetheretherketone with carbon fiber)
PPS-CF (polyphenylene sulfide with carbon fiber)

Why is CFR-TP better than steel and aluminium in engineering applications?

The high strength and high stiffness of our material in combination with low weight gives you a head start when you look for process and product improvement opportunities. Certainly when you become aware that CFR-TP does not require surface treatment to protect your product against the impact of corrosion or even aggressive environments like sea water or chemicals. It has much better fatigue resistance and damping propoerties than metals and also higher energy absorption required for crash performance; you have all you need with CFR-TP material.

Are CFR-TP Tubes helping with sustainability goals?

The tubes that Alformet produces from CFR-TP material are sustainable. The need to treat our natural resources with respect is met with the CFR-TP tubes produced by Alformet. The products and material fit in the 3R model: Reduce, Reuse and Recycle. And the applied production process in Alformet operates with renewable energy!

How do we manufacture CFR-TP Tubes for industrial purposes?

Alformet processes UD-tape made from a thermoplastic resin and reinforced with carbon fibers with laser winding (LATW). The fast and efficient process produces layers of the tape delivering a tube with customer specific length, wall thickness and reinforcement direction in the material of choice. Watch the video of the process on the right!

We also perform additional fabrication, like bending (reshaping) and machining of the tubes.

Frequently asked questions

General

Why is FRP (or CFRP/GFRP) used in Engineering?

FRP material is a versatile material with high performance characteristics. It possesses valuable engineering properties, like high strength/stiffness combined with a low density. Additionally the durability, like for instance corrosion and chemical resistance, is another characteristic that favors the application of FRT in engineering challenges.

FRP is also called CFRP when the reinforcement is carbon fiber material and GFRP when glass fibers are used.

The ‘P’ in ‘FRP’ stands for Polymer or Plastic. Alformet uses only Thermoplastic material reinforced with fibers. Thermoplastic material has the advantage of being 100% recyclable and contributes to the transition to a circular economy.

What is the difference between Fiber Reinforced Polymer or Plastic?

The word plastic is the common name for synthetic polymer, so there is no difference if you refer to synthetic material. There are three types of polymers: thermoset, thermoplastic and elastomer.

Thermoset is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin)
Thermoplastic, or thermosoftening plastic, is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling.
An elastomer is a polymer with viscoelasticity (i.e., both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus and high failure strain compared with other materials.

Fiber Reinforced Polymer/Plastic is a polymer/plastic with reinforcement from fibers. This type of material is an engineering material and substitutes metal in many applications, due to the favorable characteristics.

Alformet processes only thermoplastic material with fiber reinforcement. These are commonly called Fiber Reinforced Thermoplastics (FRTP) or Thermoplastic Composites and are 100% recyclable.

What is the difference between Fiber Reinforced Thermoplastics and Thermoplastic Composites?

Both terms refer normally to the same: Fiber Reinforced Thermoplastics is more often used as it specifically indicates that fibers are used to reinforce the thermoplastics. Examples are PP-GF (polypropylene with glass fibers) or PEEK-CF (polyetheretherketone with carbon fibers).

Thermoplastic Composite literally means that the composite (combination of two materials) consists of thermoplastic and another (reinforcing) element. Any other element that improves the characteristics can therefore be used (of which fibers is one option). For instance a sandwich panel of aluminium sheets with thermoplastic material in between is also called a (thermoplastic) composite.

Alformet processes only fiber reinforced thermoplastics with its laser winding technology. Thermoplastics are 100% recyclable.

What is CFRP and CFR-TP?

CFRP stands for Carbon Fiber Reinforced Polymer/Plastic and reflects a group of plastics that are reinforced with carbon fibers to provide it with high strength and stiffness, while reducing weight compared to most other materials like metals. The group of plastics which can be reinforced with carbon fibers, can be split in two main groups: thermoset and thermoplastics.

CFR-TP stands for Continuous Fiber Reinforced Thermoplastics. Thermoplastics reinforced with continuous fibers have other characteristics compared to continuous fiber reinforced thermosets. Thermoplastics are recyclable and fit in the circular economy model.

What is GFRP?

GFRP stands for Glass Fiber Reinforced Polymer/Plastic and reflects a group of plastics that are reinforced with glass fibers to provide it with high strength and (moderate) stiffness, while reducing weight compared to most other materials like metals. The group of plastics which can be reinforced with glass fibers, can be split in two main groups: thermoset and thermoplastics.

Thermoplastic GFRP is a subgroup within the GFRP material group. Thermoplastics reinforced with glass fibers have other characteristics compared to glass fiber reinforced thermosets. Thermoplastics are recyclable and fit in the circular economy model.

What are Continuous Fiber Reinforced (CFR) Thermoplastics?

The continuous fiber reinforced thermoplastics contain fibers that are endless or continuous. These continuous fibers offer optimal strength and stiffness as they support the full structure in contradiction to the short or long fibers, which can only bear partial loads. The highest mechanical properties of a structure can be obtained by applying continuous fibers.
