| titleOfInvention | Ultraviolet fluorescent bismaleimide resin carbon fiber prepreg for sacrificial layer |
| abstract | The invention belongs to the technical field of high polymer materials, and relates to an ultraviolet fluorescent bismaleimide resin carbon fiber prepreg for a sacrificial layer. The ultraviolet fluorescent bismaleimide resin carbon fiber prepreg is prepared from the following raw materials in parts by weight: 100 parts of bismaleimide resin matrix, 60-100 parts of process modifier, 0-50 parts of composite curing agent, 0-50 parts of auxiliary agent and 1-50 parts of ultraviolet fluorescent powder. According to the invention, the bismaleimide resin carbon fiber prepreg is prepared by adding the ultraviolet fluorescent powder into the sacrificial layer, so that the sacrificial layer and the body can be distinguished only by irradiation of an ultraviolet lamp when the composite material member is milled, the problem that the sacrificial layer of the carbon fiber prepreg is difficult to distinguish is solved, the problem that the body is easy to damage and difficult to measure if the feeding amount is improperly controlled when the carbon fiber prepreg is used as the sacrificial layer during assembling and milling is avoided, and the surface quality of the large composite material member is greatly improved. |
