技术领域technical field
本发明涉及丝线型材料片状成形制备工艺领域,具体是一种纤维丝无切削层片的制备方法。The invention relates to the field of sheet-forming preparation technology of thread-shaped materials, in particular to a method for preparing fiber filaments without cutting layers.
背景技术Background technique
针织丝、棒线等形态材料一般不能直接使用,这类丝线通常采用经编、纬编或其他纺织方法形成较大片状织物,再经裁剪和缝纫等形成半成品或成品。这种工艺方法的致命缺陷是丝线被切割,织物整体性能功能受到削弱;在特定工况下,成品或半成品不允许有接头要求时,难以制备使用。例如,关节轴承,在航空航天等领域有特别重要的用途,要求高精度、高可靠性、高稳定性和高寿命。Knitting silk, rods and other materials generally cannot be used directly. This kind of silk usually uses warp knitting, weft knitting or other textile methods to form larger sheet fabrics, and then cuts and sews them to form semi-finished or finished products. The fatal defect of this process method is that the silk thread is cut, and the overall performance of the fabric is weakened; under certain working conditions, when the finished or semi-finished product does not allow joint requirements, it is difficult to prepare and use. For example, joint bearings are particularly important in aerospace and other fields, requiring high precision, high reliability, high stability and long life.
碳纤维(carbonfiber,简称CF),它是由片状石墨微晶等有机纤维沿纤维轴向方向堆砌而成,经碳化及石墨化处理而得到的微晶石墨材料。碳纤维“外柔内刚”,质量比金属铝轻,但强度却高于钢铁,并且具有耐腐蚀、高模量的特性,在国防军工和民用方面都是重要材料。它不仅具有碳材料的固有本征特性,又兼备纺织纤维的柔软可加工性,是新一代增强纤维。Carbon fiber (CF for short) is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber and undergoing carbonization and graphitization. Carbon fiber is "soft on the outside and rigid on the inside", lighter than metal aluminum, but stronger than steel, and has the characteristics of corrosion resistance and high modulus. It is an important material in national defense and civilian applications. It not only has the inherent intrinsic characteristics of carbon materials, but also has the softness and processability of textile fibers. It is a new generation of reinforcing fibers.
碳纤维是一种含碳量在95%以上的高强度、高模量纤维的新型纤维材料,适于做滑动摩擦衬层。而关节轴承滑动摩擦副为球面副,当按织物或按聚四氟乙烯层制备方法作碳纤维复合材料衬时,就会裁剪、形成接缝或难以安装使用,必须采用新的制衬方法,保证丝线连续、不切割、无接缝。Carbon fiber is a new type of high-strength, high-modulus fiber with a carbon content of more than 95%, which is suitable for sliding friction linings. The sliding friction pair of the joint bearing is a spherical pair. When the carbon fiber composite lining is made according to the fabric or the polytetrafluoroethylene layer preparation method, it will be cut, seamed or difficult to install and use. A new lining method must be adopted to ensure The silk thread is continuous, not cut, and has no seams.
因此,本发明提供一种纤维丝无切削层片的制备方法。Accordingly, the present invention provides a method for the preparation of fiber-filament-free cutting plies.
