The manufacturing method sequentially comprises the following steps: the manufacturing method comprises the steps of coating a release agent on the outer surface of a mandrel, wrapping a carbon fiber sheet by a glass fiber sheet, fixing a dual-phase cloth, fixing a resin stripe net, covering a vacuum film, exhausting air in the vacuum film, releasing the vacuum film and manufacturing a CFRP static filter. The method can ensure that the products with basically consistent quality are produced, and avoids the problem that the quality of the products is uneven due to different technical levels of workers. The method can effectively reduce the defect rate of products and reduce the exposure of hands or arms of workers. The safe work of the user can be ensured, the productivity is improved, and the production cost is reduced.

摘要：【中文】本发明属于催化剂领域，涉及异斯特维醇衍生物，特别是指一种无溶剂催化剂及其制备方法和应用。所述的异斯特维醇衍生物通过在手性骨架上引入取代的方酰胺基团，实现“优势骨架合理组合”。该类衍生物通过异斯特维醇胺类衍生物和方酸二甲酯以及环己二胺衍生物经两步亲核取代反应制得，合成步骤简单，反应条件温和。本发明同时还提供了该衍生物作为有机催化剂在无溶剂条件下在合成硝基取代手性化合物中的应用。 【EN】The invention belongs to the field of catalysts, relates to isosteviol derivatives, and particularly relates to a solvent-free catalyst and a preparation method and application thereof. The isosteviol derivative realizes the reasonable combination of advantageous skeletons by introducing substituted squaramide groups on a chiral skeleton. The derivative is prepared by two steps of nucleophilic substitution reaction of isosteviolamine derivatives, dimethyl squarate and cyclohexanediamine derivatives, and has the advantages of simple synthesis steps and mild reaction conditions. The invention also provides application of the derivative as an organic catalyst in synthesizing a nitro-substituted chiral compound under the solvent-free condition.
