Embodiment 1

[0052] Choose a unidirectional carbon fiber prepreg tape whose resin base material is PC, with a density of 1.5g / cm 3 , and then use a knife to cut the unidirectional carbon fiber prepreg tape into 4 layers of carbon fiber prepreg sheets, use a stamping die to cut holes in two layers of carbon fiber prepreg sheets, the hole diameter is 5mm, and the distance between the center of the hole is 15mm, and then the layer without cutting holes Carbon fiber prepreg is used as the first layer, and then two layers of carbon fiber prepreg with holes are laid on the first layer of carbon fiber prepreg in sequence, and finally the fourth layer is laid without another layer of carbon fiber prepreg without holes. The layup angle is 0° / 90° / 0° / 90°, and the carbon fiber preform of this embodiment is obtained, which is put into a hot-pressing device to prepare the shell of the wearable device through hot-pressing, and the hot-pressing temperature is 160 ℃, the hot pressing time is 1min, and the ...

Embodiment 2

[0054] Choose a woven carbon fiber prepreg cloth with epoxy resin as the resin base material, with a density of 1.2g / cm 3 , and then use a knife to cut the unidirectional carbon fiber prepreg tape into 6 layers of carbon fiber prepreg sheets, use a stamping die to cut holes in four layers of carbon fiber prepreg sheets, the hole diameter is 15mm, and the center distance of the holes is 30mm, and then the layer without cutting holes Carbon fiber prepreg is used as the first layer, and then four layers of carbon fiber prepreg with cut holes are sequentially laid on the first layer of carbon fiber prepreg, and finally the sixth layer is laid without another layer of carbon fiber prepreg without cut holes. Obtain the carbon fiber preform of this example, put it into the hot pressing equipment and prepare the shell of the wearable device by hot pressing. The carbon fiber prepreg under the same conditions but without the hole cuts achieved a weight loss of 10.6%.

Abstract

The invention discloses a layer laying method of a carbon fiber prepreg, a carbon fiber prefabricated product and wearable equipment, and the layer laying method of the carbon fiber prepreg comprises the following steps: cutting an original carbon fiber prepreg into multiple layers of carbon fiber prepreg sheets; cutting a part of the carbon fiber prepreg sheets into holes so as to form the carbon fiber prepreg sheets with a plurality of through holes; taking a layer of uncut carbon fiber prepreg sheet as a bottom layer; sequentially stacking a plurality of layers of perforated carbon fiber prepreg sheets on the bottom layer; and laying the other layer of uncut carbon fiber prepreg sheet on the cut carbon fiber prepreg sheet as a top layer to obtain the carbon fiber prefabricated product. The carbon fiber prepreg sheets located at the bottom layer and the top layer are not provided with cut holes, so that the flat appearance can be kept, the appearance of the shell of the wearable equipment cannot be damaged after hot press molding, and the carbon fiber prepreg sheets located in the middle are provided with a plurality of through holes, so that the weight of the wearable equipment can be reduced, and the use comfort of a user is improved.

Description

technical field [0001] The invention relates to the field of wearable devices, in particular to a layering method of carbon fiber prepreg, a carbon fiber prefabricated product and a wearable device. Background technique [0002] Wearable devices have brought great changes to our life and perception, and their applications are becoming more and more extensive. For example, the virtual reality technology of VR (Virtual Reality, virtual reality) equipment has been recognized by more and more people. Users experience the most realistic feelings in the virtual reality world. It makes people feel like they are there. At the same time, virtual reality has all the perception functions that human beings have, such as hearing, vision, touch, taste, smell and other perception systems; finally, it has a super simulation system, which truly realizes human-computer interaction and makes people feel more comfortable during operation. , you can operate at will and get the most realistic f...
