preparation example Construction

[0023] This embodiment provides a resin fiber composite material, the preparation method of which includes the following steps:

[0024] S1) Prepreg and pre-curing: soak the sheet-shaped wave-absorbing material in a thermosetting resin solution, and then pre-cure the soaked sheet-shaped wave-absorbing material to form a sheet-shaped wave-absorbing material prepreg, preferably the sheet-shaped wave-absorbing material The material is preferably any one of glass fiber cloth, aramid fiber cloth, and quartz fiber cloth. The thermosetting resin solution of this step preferably adopts epoxy resin glue solution, cyanate resin glue solution, phenolic resin glue solution, bismaleic anhydride resin any one or the mixed solution of two or more, more in thermosetting resin solution Optionally add appropriate amount of curing agent and / or accelerator. The pre-curing temperature in this step is preferably 80-100° C., and the pre-curing time is preferably 0.2-1 hour.

[0025] S2) Preparatio...

Embodiment 1

[0032] 1. Prepreg and precuring

[0033] (1.1) Prepare quartz fiber cloth for use;

[0034] (1.2) Prepare thermosetting resin solution for epoxy resin system: 140 parts of bisphenol A epoxy resin, 7 parts of dicyandiamide, and 7 parts of acrylic amine are mixed evenly at 70°C and placed for later use;

[0035] (1.3) Soak the quartz fiber cloth in the above resin solution;

[0036] (1.4) Put the infiltrated quartz fiber cloth into an oven for curing at a curing temperature of 95°C for 0.5 hours to prepare a quartz fiber cloth prepreg.

[0037] 2. Preparation of conductive paste

[0038] (2.1) Prepare the same epoxy resin system thermosetting resin solution as in step 1: 140 parts of bisphenol A epoxy resin, 7 parts of dicyandiamide, and 7 parts of acrylic amine, mix well at 70°C and set aside for later use.

[0039] (2.2) Add 1% by volume conductive graphite to the mixed system obtained in step (2.1).

[0040] 3. Prepreg lamination and conductive paste coating

Abstract

The invention discloses a method for preparing a resin fiber composite material and the resin fiber composite material. The method comprises the following steps: soaking a sheet-shaped wave-absorbing material in a thermosetting resin solution, and then soaking the soaked sheet-shaped wave-absorbing material Precure to form a sheet-shaped wave-absorbing material prepreg; take an appropriate amount of the thermosetting resin solution used in step S1), add conductive particles with a volume ratio of 1% to 30% and stir evenly to prepare a conductive paste; put the sheet-shaped wave-absorbing material prepreg After stacking, apply the conductive paste on the part that needs to be electroplated; cure the product obtained in step S3), the curing temperature is 80-250°C, the curing pressure is 0.1-3Mpa, and the curing time is 1-12 hours; The cured product in step S4) is placed in the electroplating solution for electroplating. The invention has the advantages of simple process and the electroplating layer is not easy to fall off.

Description

technical field [0001] The invention relates to the technical field of supermaterials, in particular to a method for preparing a resin fiber composite material and the resin fiber composite material. Background technique [0002] The electroplating of resin fiber composite materials is difficult, and the surface is not conductive, so it needs special surface conductive treatment, but the processing is difficult and the uniformity is poor, which seriously affects the product effect. The existing process mainly uses some special and complicated treatments on the composite material, such as spraying conductive liquid, palladium liquid micro-etching, chemical deposition of metal, etc., to make it conductive. Influence, and the adhesion of the electroplated metal layer is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing a resin fiber composite material with simple process and good meta...
