Graphene fibers, when graphitized at high temperatures, achieve thermal conductivities around 1290 W m⁻¹K⁻¹, surpassing most metals, but require per-fiber measurement for accurate application-specific values.

Penguin Shipyard International has completed and delivered the largest composite superstructure ever built in Singapore for the Republic of Singapore Navy's new Multi Role Combat Vessel, with the first of six structures handed over to Saab on June 27, 2026. The use of carbon fiber composites in the superstructure reduces weight and radar cross-section, enhancing the ship's stability and stealth capabilities compared to conventional steel designs.

The Boeing 787 and Airbus A350 use carbon-fiber-reinforced composite materials for roughly 50% of their airframe by weight, making tail strike damage harder to detect and repair than on metal-fuselage aircraft like the Boeing 777, as illustrated by an Air France A350 that required nearly ten months of repairs after a 2024 tail strike in Toronto. For the carbon fiber composites sector, the article highlights that barely visible impact damage, complex non-destructive inspection requirements, and process-sensitive repair procedures drive significant maintenance downtime and cost, underscoring the need for advanced damage detection and repair capabilities in aerospace composite applications.

CSIC researchers developed an 18-micron graphene-polymer composite separator combining polypropylene with 0.5 wt% reduced graphene oxide, achieving 4x greater puncture resistance and a 60% reduction in thermal-runaway initiation temperatures in lithium-ion batteries. The development advances reduced graphene oxide as a functional additive in battery separators, with pilot-scale production underway alongside a Spanish cell manufacturer targeting NCM-based EV applications.

Advanced Graphene Products has begun supplying ISO 10993-certified graphene oxide from its Zielona Gora facility to Boston Scientific under a $4.2 million contract for a two-year, 480-patient FDA-approved clinical trial of antimicrobial-coated cardiac catheters. The trial represents a direct application of graphene oxide in regulated medical devices, with a potential commercial supply pathway if Boston Scientific proceeds to FDA submission.
