Carbon fiber composite material, preparation method and carbon fiber profile
The invention discloses a carbon fiber composite material, a preparation method and a carbon fiber profile. Relates to the technical field of carbon fiber composites. The carbon fiber composite material is prepared from the following components in parts by weight: 100 parts of bamboo pulp fiber; 0.2 to 1.5 parts of graphene oxide; 1.5 to 2.8 parts of attapulgite clay; and 0.35 to 0.6 part of a coupling agent. The preparation method comprises the following steps: adding the bamboo pulp fibers into water, and stirring to form turbid liquid; adding graphene oxide, attapulgite and a coupling agent into the turbid liquid, stirring, and aging at normal temperature to obtain a solid mixture; performing dehydration treatment and ultraviolet irradiation to obtain a cross-linked fiber material; carrying out pre-oxidation treatment; and carrying out carbonization treatment. The carbon fiber profile is prepared from the carbon fiber composite material. The graphene oxide is partially embedded into a porous channel of the attapulgite; the porous channels facilitate electron movement, and when the carbon fiber composite material is ripped, similar graphene oxide drives the attapulgite and the carbon fibers to move, so that self-healing is realized.
本申请公开了一种碳纤维复合材料、制备方法及碳纤维型材；涉及碳纤维复合材料技术领域。碳纤维复合材料由以下按重量份数计的组分制备得到：竹浆纤维100份；氧化石墨烯0.2～1.5份；凹凸棒土1.5～2.8份；偶联剂0.35～0.6份。制备方法为：竹浆纤维加入水中，搅拌形成悬浊液；将氧化石墨烯、凹凸棒土以及偶联剂加入悬浊液，搅拌，常温下陈化处理，得到固状混合物；脱水处理，紫外线照射，得到交联纤维材料；预氧化处理；碳化处理。碳纤维型材，由上述碳纤维复合材料制备得到。氧化石墨烯部分嵌入至凹凸棒土的多孔通道内；多孔通道便于电子移动，碳纤维复合材料被划开时，相近的氧化石墨烯带动凹凸棒土、碳纤维移动，实现自愈合。
