Thermoplastic carbon fiber prepreg tape laminated plate sample preparation device

Abstract

The invention relates to a thermoplastic carbon fiber prepreg tape laminated plate sample preparation device, and belongs to the field of composite material forming processing. The thermoplastic carbon fiber prepreg tape laminated plate sample preparation device comprises a mounting base, a sample preparation mold, a hot pressing block, a pressing assembly and a pressing sheet, a sample preparation groove which is as wide as a to-be-processed carbon fiber prepreg tape laminated layer and is used for positioning the to-be-processed carbon fiber prepreg tape laminated layer is formed in the sample preparation mold, and the pressing sheet is detachably connected with the sample preparation mold through a pressing bolt so as to press the carbon fiber prepreg tape laminated layer extending out of the sample preparation groove; the hot-pressing block conducts heat and is internally provided with a heating piece for heating the hot-pressing block, the heating piece is connected with the temperature control assembly, and the hot-pressing block is used for being placed in the sample preparation groove to melt resin on the carbon fiber prepreg tape; and the pressing assembly is fixed on the hot pressing block and is used for carrying out hot pressing operation under the manual action and taking the hot pressing block out of the sample preparation groove under the manual action. According to the sample preparation device, the consistency of the fiber direction and tension of the thermoplastic carbon fiber prepreg tape laminated plate can be ensured, and the operation safety is improved.

Description

technical field [0001] The invention belongs to the field of composite material forming and processing, in particular to a sample preparation device for a thermoplastic carbon fiber prepreg tape laminate. Background technique [0002] Carbon fiber prepreg tape is a necessary intermediate for the preparation of carbon fiber composite materials. According to the difference of resin matrix, prepreg tape can be divided into thermoplastic prepreg tape and thermosetting prepreg tape. Compared with traditional thermosetting carbon fiber prepreg tape, thermoplastic carbon fiber prepreg tape has the advantages of short molding cycle, recyclability, environmental protection, high efficiency and high performance. It is widely used in aerospace, wind power blades, automobiles, sports equipment and other fields. [0003] Thermoplastic carbon fiber prepreg tapes need to be heated to melt the resin when preparing carbon fiber composite products, and then prepreg tapes with corresponding an...
