Correcto

• 碳纤维复合材料在新能源汽车车身中广泛应用，不仅减轻了重量，也提高了能效，是轻量化技术成熟的重要突破。(Carbon fibre composite materials are widely used in new energy vehicle bodies, reducing weight and improving energy efficiency, and they are an important breakthrough in the maturity of lightweight technology.)
• 调查显示，长期高膳食纤维摄入的人，结直肠癌、二型糖尿病和心血管病风险都更低，为慢性病预防提供了有力依据。(Studies show that people who consume a high amount of dietary fibre long term have lower risks of colorectal cancer, type 2 diabetes, and cardiovascular disease, providing strong evidence for chronic disease prevention.)

Incorrecto

• 纤维 without a qualifier when precision is required — 天然纤维, 合成纤维, 膳食纤维, 碳纤维, and 肌肉纤维 all refer to very different substances and contexts; an unqualified 纤维 in technical writing can cause ambiguity
