Nippon Graphite Fiber ? Low Modulus

Description

Low modulus, high elongation

Carbon fiber — Low-modulus pitch carbon

Strengths: Cost-oriented pitch carbon with useful conductivity, low density and moderate reinforcement capability.

When to use: Select for general composites or conductive/thermal functions when extreme mechanical performance is not required.

Key tradeoffs: Mechanical performance is below structural PAN carbon; conductive and unsuitable for RF-transparent designs.

Relative cost	6/10 — Moderate–high — specialty pitch-derived grade, less costly than UHM pitch but above commodity PAN carbon.
EM transparency	1/10 — Very poor — conductive carbon is poor for EM transparency.
Temperature / fire resistance	6/10 — Good — non-melting in inert service, but oxidation in air and matrix limits remain.
Impact / penetration resistance	5/10 — Moderate — lower stiffness can improve compliance, but impact capability is still limited by carbon's brittle failure. Stored TDS elongation: 1.5%.
Electrical / thermal conductivity	8/10 — Very high — pitch origin can provide high electrical/thermal transport even at lower modulus.
Specific tensile strength	5/10 — 5/10 \| 1297.3 kN·m/kg \| Product TDS
Atmospheric durability	9/10 — Excellent — carbon fiber is intrinsically resistant to UV, moisture and salt exposure; long-term laminate durability is usually governed by sizing, matrix, galvanic coupling and interfaces rather than the fiber.
Sustainability (CO₂e)	4/10 — 24.00 kg CO₂e/kg fiber — High emissions — data quality: Low
