Carbon Fiber Composites & FR4 / G10 Epoxy Glass Machining

Ultimate Tensile Modulus, High Dielectric Insulation & Zero Delamination Routing.

Carbon Fiber Reinforced Polymer (CFRP) and FR4 / G10 woven glass-epoxy laminates represent the pinnacle of stiffness-to-weight and electrical insulation. Carbon fiber laminates offer higher specific stiffness than titanium at half the density, ideal for drone airframes and medical imaging tables. FR4/G10 provides supreme electrical breakdown resistance (>35 kV/mm), zero water absorption, and high compressive strength for motor rotor wedges and transformer barrier plates.

Material Engineering for Carbon Fiber Composites & FR4 / G10 Epoxy Glass Machining

Certified raw material sourcing, certified heat-treatment verification, and extreme tolerance manufacturing calibrated specifically for Carbon Fiber Composites & FR4 / G10 Epoxy Glass Machining components.

Zero Delamination Routing

High-rake compression diamond-coated router bits eliminate top and bottom fiber breakout and fraying.

X-Ray Radiolucency

Carbon fiber allows X-rays to pass through cleanly, ideal for surgical positioning tables and radiolucent arms.

UL 94 V-0 Flame Retardant (FR4)

Self-extinguishing brominated epoxy matrix prevents electrical arc fire propagation.

High Compressive Strength

G10 withstands over 400 MPa compressive load without creeping or losing electrical isolation.

Frequently Asked Questions

Common engineering questions regarding tolerances, material traceability, and turnaround for Carbon Fiber Composites & FR4 / G10 Epoxy Glass Machining.

How do you prevent carbon fiber from delaminating during drilling? +
We use specialized left-hand/right-hand compression diamond router bits and sacrificial backup boards that compress the laminate fibers inward during the cut, preventing delamination.
What is the difference between G10 and FR4? +
G10 and FR4 are both woven fiberglass cloth embedded in epoxy resin. FR4 contains flame-retardant bromine additives achieving UL 94 V-0, while G10 is the non-flame retardant version.
Can you machine 3K weave and unidirectional carbon fiber? +
Yes. We machine 3K plain weave, 3K twill, forged carbon composite, and unidirectional prepreg laminates.
How do you handle hazardous composite dust? +
All composite CNC routing is conducted with localized high-efficiency vacuum hoods or submerged under fluid mist curtains to protect operators and prevent machine guide contamination.
