LIGHTWEIGHT MATERIALS The majority of the lightweight materials have been designed to match application-specific needs and satisfy the corresponding requirements. Fiber-reinforced materials can be categorized according to the fiber used and the matrix. Sandwich constructions are distinguished by their core layer: honeycomb core or foam core. Other multilayer composites (stacks) combine the advantages of fiber-reinforced materials with those of light metals, for example. CFRP – carbon-fiber-reinforced plastic Highest strength and rigidity combined with very low density make CFRP the lightweight...

AFRP – aramid-fiber reinforced plastic Their low density makes aramid fibers extremely light, and they also feature high tensile strength. Aramid fibers exhibit ductile behavior instead of brittleness. When machining AFRP, extreme fraying of the fibers frequently occurs. However, good results can be achieved if especially adapted saws, drill bits and end mills are used for this material. Sandwich constructions The challenge with machining of sandwich constructions is not to destroy the delicate honeycomb or foam cores. LEUCO provides special end mills and drill bits as well as circular saw blades...

APPLICATIONS Components made of fiber-reinforced plastics are produced with a near net shape, but reworking is almost always necessary. Machining processes are very often applied for such rework tasks. They have proven to provide higher dimensional accuracy and flexibility compared to water jet cutting and laser processing. Milling is used to create perfect external and internal contours and functional surfaces. Furthermore, circular milling or wave milling processes can be used to produce holes in the required quality. Frequent problems related to milling are insufficient cutting quality (protruding...

COATINGS State-of-the-art coating technologies for durable tools The aerospace industry places high demands on cutting tools, as modern composite materials such as glass and carbon fiber-reinforced materials are very abrasive and are sometimes combined with light metals such as aluminium and titanium. Polycrystalline diamond (PCD) is a proven choice, but carbide tools are also used due to size and geometry constraints. CVD diamond coatings are used to maximize the edge life and the performance of these tools. These coatings offer outstanding hardness, abrasion and heat resistance which makes...

COATED DRILL BITS LEUCO offers customized solutions for drilling composite materials, depending on the material and application. The LEUCO drill bit portfolio I takes into account the heterogeneous structure of materials, which can lead to layer detachment or delamination due to uneven loading of the fibers. I minimizes tool wear due to abrasive fibres and reduces tool and dimensional deviation costs I keeps the heat generated by friction at a low level in order to soften the matrix as little as possible and not impair other material properties. In addition to PCD drill bits for high volume production,...
