碳纤维织造针刺件是加工碳纤维预制体的核心部件，特指刺针及其固定件。刺针通常采用优质合金钢制造，其工作段设计有独特的来福线和储纤槽。这种结构能在Z向穿刺碳纤维网毡时，有效减少对脆性纤维的损伤，并引导纤维进行顺畅转移与缠结，从而形成结构完整、性能优异的准三维立体织物预制体，是生产高性能碳/碳、碳/陶复合材料的关键工装。

Carbon Fiber Weaving Needling Parts are core components for processing carbon fiber preforms, specifically referring to barbed needles and their fixtures. The needles are typically made of high-quality alloy steel, with their working section designed with unique rifling grooves and fiber storage slots. This structure effectively minimizes damage to brittle fibers during the Z-direction piercing of carbon fiber web felts while facilitating smooth fiber transfer and entanglement. This process forms structurally integral and high-performance quasi-three-dimensional fabric preforms, serving as critical tooling for producing high-performance carbon/carbon and carbon/ceramic composites.
