Carbon Fiber Reinforced Polymers (CFRP)
Carbon Fiber Reinforced Polymers (CFRP) include
an array of materials made up of woven carbon fiber held together
by resins and plastics. The properties of CFRP vary widely based
on the direction of the woven fiber and type of resin used. To add
strength, honeycombed core structures and/or solid layers of titanium
and aluminum are often combined with CFRP to form what is known
as a composite stack.
The strength to weight ratio of CFRP translates into lighter, faster
more fuel efficient aircraft. But advanced composites present a
host of new machining challenges to aerospace and cutting tool manufacturers
alike. Holes drilled in aircraft structures must be made cleanly,
with no frayed fibers or fibers pulled out of alignment. Maintaining
sharp cutting edges is critical to making these clean cuts and
avoiding delamination of the composite layers.
DiaTiger® diamond coating is quickly becoming an established
solution for machining all types of aircraft composites, providing
significant productivity gains and cost savings over traditional
tools. Diamond Tool Coating works with an extensive network of cutting
tool manufacturers to supply both standard and custom diamond coated
tools for composite applications.
