The invention discloses a method for modifying reinforced fibers. The method comprises the following steps: S1, cleaning the surfaces of the fibers; s2, activating the coupling agent gasified under a vacuum condition by adopting plasma, so that the coupling agent is subjected to vapor deposition on the surface of the fiber, and the fiber with a coupling agent layer is obtained; and S3, applying an impregnating compound containing a film-forming agent to the surface of the coupling agent layer of the fiber obtained in the S2, and drying to obtain a reinforced fiber finished product with a resin modified layer. According to the modification method of the reinforced fiber, coupling agent plasma vapor deposition is carried out on the surface of the fiber, a compact and uniform coupling agent layer is formed on the surface of the fiber, sites of reaction between the surface of the fiber and a subsequent impregnating compound are increased, and sufficient reaction of a film-forming agent and other impregnating compound components on the surface of the fiber is promoted to form a tightly-attached resin modification layer. The invention also discloses a reinforced fiber and a composite material containing the reinforced fiber.
本发明公开了一种增强纤维的改性方法，包括以下步骤：S1：清理纤维的表面；S2：采用等离子体激活真空条件下气化的偶联剂，使偶联剂气相沉积于纤维表面，获得具有偶联剂层的纤维；S3：将包含成膜剂的浸润剂施加于S2所得纤维的偶联剂层表面，烘干，获得具有树脂改性层的增强纤维成品。该发明增强纤维的改性方法将偶联剂等离子体气相沉积于纤维表面，在纤维表面形成致密、均匀的偶联剂层，增加纤维表面与后续浸润剂反应的位点，促进成膜剂和其他浸润剂组分在纤维表面的充分反应形成附着紧密的树脂改性层。本发明还公开了一种增强纤维以及包含增强纤维的复合材料。
