Reinforced carbonfiber

In 2015 Windform XT was replaced by Windform XT 2.0, with improvements in mechanical properties including +8% increase in tensile strength, +22% in tensile modulus, and a +46% increase in elongation at break.

Coating cutting and forming tools with PVD used in machines for manufacturing products significantly increase their service life and performance compared with uncoated tools and save on valuable raw materials, minimizing the environmental impact and helping to preserve natural resources.

PVD coatings are applied in self-contained systems of different sizes. In the PVD process, a high-purity, solid coating material (metals such as titanium, chromium, and aluminum) is either evaporated by heat (arc evaporation) or by bombardment with ions (sputtering). At the same time, a reactive gas (e.g., nitrogen or carbon-containing gas) is added. The gas forms a compound with the metal vapor, which is then deposited on the tools or components as a thin, highly adherent coating. The process is carried out under high vacuum and, in most cases, at temperatures between 150 and 500 °C. A uniform coating thickness is obtained by rotating the parts at a constant speed around several axes.

In view of such amazing characteristics, the greatest disadvantage is cost which still remains high. Fortunately the new, continuing technological advancements in manufacturing allow for more cost-effective products.

In this scenario – driven by the demand of higher quality products, greater choice, flexibility – one of the most popular performance materials is carbon fiber reinforced polymer composite, thanks to its undeniable strength and stiffness: these characteristics when combined with the capabilities of professional 3D printing provide unrivalled manufacturing solutions.

A carbon fiber reinforced polymer is an advanced composite material which consists of two parts: a matrix and a fiber reinforcement. In this case, the reinforcement is carbon fiber, intended as primary structural component. Fiber can be continuous or short. The expression can be shorten in CFRP; “P” can stand for “plastic” also, not only for “polymer”.

For many years CRP Technology has been at the forefront in the research, development and creation of carbon fiber reinforced composite materials to be used with professional 3D printing process.

The process is occurring especially amongst end-users, who begin to fully understand the value-add that 3D printing brings to their supply chain.

The carbon fiber reinforced polymer has many advantages as lightweight. It is also very strong and stiff thanks to the carbon fiber reinforcement whereas the polymer gives protection and grasp on the fiber along with toughness.

CFRPs are commonly used in those sectors that require stiffness and a high strength-to-weight ratio, for example aerospace, automotive, civil engineering.

The coating properties, such as hardness, structure, chemical and temperature resistance, and adhesion, can be precisely controlled by the choice of metal and gas.

A carbon fiber reinforced polymer is an advanced composite material which consists of two parts: a matrix and a fiber reinforcement. In this case, the reinforcement is carbon fiber, intended as primary structural component. Fiber can be continuous or short.

PVD (Physical vapor deposition) is a technique for creating extremely hard and very thin coatings of a few thousandths of a millimeter.

Nowadays the Windform range of materials for additive manufacturing comprises many composites which are carbon fiber filled, each with specific high performance characteristics: Windform SP, Windform RS, Windform FR1, the first UL94 V-0 carbon-filled flame retardant laser sintering material ever.

The key to the success of PVD coatings is finding the right coating solution for a specific application. For tools and components subjected to friction and wear, the first step is analysis of the entire tribological system — the parts and their required materials, the desired surface finish, the environment, and wear mechanism.

Precision components in vehicles, aircrafts, machines, medical technology, semiconductor technology, power generation and in many other devices are coated with PVD coatings to enable them to function more reliably, powerfully, and efficiently. The result is a reduction in friction and an increase in service life, which contributes to sustainability.
