Fiber grade is the single biggest driver of sheet performance and price. Both T300 and T700 are proven carbon fibers — the right choice depends on your load case and budget.

T300: The Reliable Workhorse

T300-class fiber offers an industry-standard tensile strength around 3,530 MPa. It is cost-effective, widely available, and more than sufficient for panels, brackets, jigs and decorative applications where loads are moderate.

T700: When Strength Pays for Itself

T700-class fiber raises tensile strength to roughly 4,900 MPa — about 40% higher — at similar modulus. For UAV frames, high-load structural parts and weight-critical programs, the strength-to-weight gain usually justifies the premium.

Practical Selection Tips

• Match fiber grade to load path — don't pay for T700 where T300 carries the load easily.
• Combine grades: T300 plies in low-stress zones, T700 where stress concentrates.
• Ask for laminate calculations — we can compare both options against your requirements before you commit.

Curing defines laminate quality. The choice between autoclave and out-of-autoclave (OoA) processing affects strength, cost and lead time.

Autoclave Curing: Maximum Performance

Pressure during cure compresses voids out of the laminate, delivering the lowest void content and highest, most repeatable mechanical properties. It remains the reference process for aerospace-grade and primary structures.

OoA Quick-Cure Prepreg: Speed and Value

Modern OoA prepreg systems cure in oven or vacuum-bag-only conditions — some in a few hours. For secondary structures, prototypes and cost-sensitive programs, properties are fully adequate and lead times shrink dramatically.

How We Help You Decide

• Structural, safety-critical or long-term fatigue loading → autoclave.
• Fast iterations, moderate loads, budget or deadline pressure → OoA.
• We run both processes and will recommend honestly — including when a mixed approach wins.

Carbon fiber parts are only as good as their machining. Composite materials machine differently from metal — wrong parameters cause delamination, fiber pull-out and out-of-tolerance features.

One Setup, Full Geometry

Five-axis machines reach contoured surfaces, angled holes and undercut features without re-fixturing. Every re-clamp is a tolerance risk; 5-axis removes that risk and holds ±0.05 mm across complex parts.

Composite-Specific Expertise

• Tool paths engineered for fiber direction — clean edges, no fraying.
• Diamond-coated and PCD tooling for abrasive carbon fibers.
• Dust extraction and process controls for consistent, repeatable results.

What It Means for You

Molded near-net-shape, then machined to final tolerances — this two-step approach delivers parts that fit your assembly the first time, at a fraction of full-machining cost.

As NEV platforms chase range and efficiency, carbon fiber adoption is accelerating — but not everywhere. The winning applications share one trait: weight saved directly buys performance.

High-Value Zones Today

• Battery enclosure panels — structural stiffness with significant weight savings.
• Motor and engine covers — stiffness, heat tolerance, premium surface finish.
• Structural brackets and crossmembers — localized reinforcement where space is tight.

The Cost Equation Is Shifting

Prepreg supply has stabilized and molding processes (including OoA quick-cure systems) are cutting cycle times. For mid-volume NEV programs, hybrid designs — carbon fiber only where it earns its place — are becoming the standard playbook.

Our Role

We support NEV suppliers with panels, covers and structural parts from prototype to batch production, backed by laminate-level engineering discussions in English.
