How to Avoid Composite Delamination With Compression Cutters
Using Compression Cutter End Mills in Composite Materials. Composite materials are generally machined with standard metal cutting end mills, which generate exclusively up or down cutting forces, depending on if they have right or left hand flute geometry. These uni-directional forces cause delamination (Figure 1).
Textile Composite
Textile composite production methods are attractive over conventional unidirectional laminate composites due to their higher production rate. Textile composites are also attractive due to yarn interlacing, which improves structural stability and damage tolerance [3].Because of these factors the use of textile composites is increasing in aerospace, …

Textile Composites
2,863. Textile composites are fiber-reinforced composite materials. The form of textile fabric being used as reinforcement are: woven, knitted, braided. Textile-reinforced composite materials (TRCM) are part of the general class of engineering materials called composite materials. There are two categories of constituent materials:
COMPOSITE MATERIALS AND STRUCTURES
The design of a composite material always precedes that of a composite structure. A composite material can be effectively tailored to suit a particular design need. It is obligatory that a composite structural designer should have a thorough knowledge about the process and development of composite materials and their characteristic behaviour.

Wind turbine blades: Glass vs. carbon fiber | CompositesWorld
These blades have the same width as the company's 44m/144-ft blades, but they sweep an area that is 55 percent larger. The result is considerably higher energy output. More recently, GE Energy (Greenville, S.C.) joined the fray, specifying carbon fiber in its next-generation wind blades, including the 48.7m/160-ft blades for its 1.6-100 turbine.
Best practices in the CNC machining of composites
Speeds must be maintained at 400-500 surface feet per minute (sfm), as this works for most material types. If you are machining solid composites, bring the spindle speed down to one-third of those values; you can also go through the cutting tool provider to learn about proper parameters. 6. Pick the right tool holder.
