本研究は、亜麻繊維、フラン樹脂、バイオチャーを組み合わせた低環境負荷材料システムを提案し、A1段階でのカーボンニュートラルを達成。19.1wt%のバイオチャー添加で質量あたりの曲げ弾性率と強度がそれぞれ15.1%、16.3%低下するものの、化石由来エポキシ系に比べて優れたエコメカニカル性能を示す。コアレサー巻き付け構造にも適用可能で、再生可能・カーボンニュートラルな軽量構造材料としての可能性を実証した。
English
This study proposes a low-impact material system combining flax fibers, furan resin, and biochar filler, achieving A1 carbon neutrality with minimal mechanical trade-offs. Incorporating 19.1 wt% biochar reduced mass-specific flexural modulus and strength by 15.1% and 16.3%, respectively. The system was also applied to coreless filament-wound structures, demonstrating processability and adequate performance. The flax–furan–biochar system offers a fully renewable, carbon-neutral/negative solution for lightweight structural applications.

日本のGX文脈において
本論文は、日本の複合材料産業（航空機・自動車・建設）にとって、製品カーボンフットプリント削減の具体的な技術選択肢を提供する。SSBJやサプライチェーン排出量算定において、材料段階でのカーボンニュートラルは重要な要素であり、特にScope3上流削減に貢献し得る。
In the global GX context
This paper provides empirical evidence for carbon-neutral composite materials, directly relevant to global frameworks like the EU's CSRD and the proposed Product Environmental Footprint (PEF) rules. The cradle-to-gate LCA methodology and the 'carbon-neutral' material system offer a blueprint for manufacturers aiming to meet net-zero targets, especially in transport and construction sectors where lightweighting is critical.

📄 Abstract（原文）
Motivated by the demand for sustainable thermoset matrix systems, this study proposes several approaches; the most effective combines flax fibers, furan resin, and biochar filler into a low-impact material system. Eco-mechanical performance was experimentally assessed at the material level via four-point bending and at the structural level via axial compression tests, using global warming potential as the sustainability metric considering LCA module A1, with estimates extended to cradle-to-gate (A1–A3). Incorporating 19.1 wt% biochar achieved A1 carbon neutrality, with 15.1% and 16.3% reductions in mass-specific flexural modulus and strength, respectively. Up to 27.6 wt% biochar was implemented in (hybrid) coreless filament-wound structures, while maintaining processability and adequate mechanical performance. In flax–epoxy systems, biochar addition improved eco-mechanical performance but could not achieve A1 carbon neutrality. The proposed flax–furan–biochar system offers a fully renewable, carbon-neutral/carbon-negative, mechanically viable solution for fiber-composite lightweight structural applications.
