Abstract
The invention discloses a forming process of glass fiber reinforced plastics, which comprises the following steps of: adding an activated carbon fiber wave absorber to epoxy rein and stirring; adding a curing agent and stirring; brushing a layer of resin transparent layer on a die by using a brush; paving glass fiber cloth on the die, brushing a resin mixture and flattening the glass fiber cloth with a rubber roller; paving 25 layers of the glass fiber cloth according to the former step to form glass fiber cloth; covering an upper die and putting the upper die in an drying oven; gradiently heating; cooling; and carrying out die opening. According to the forming process disclosed by the invention, the activated carbon fiber is used as the wave absorber, the conductivity gradually rises along with the increase of the content of the activated carbon fiber; and the change rule of the conductivity is basically consistent with the change rule of the wave absorption performance of the material.
Description
Technical field
The present invention relates to a kind of fiberglass moulding process.
Background technology
Absorbing material be meant can absorb, the incident electromagnetic wave that decays, and with electromagnetic energy convert the energy of other form into and consume one type of functional material, the bending property of absorbing material and absorbing property have very big influence to the composite electrical conductivity.
Summary of the invention
The object of the present invention is to provide a kind of fiberglass moulding process.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of fiberglass moulding process comprises:
With stirring in the activated carbon fiber wave absorbing agent adding epoxy resin;
Adding curing agent stirs;
On mould, brush one deck resin wave permeation layer with brush;
Glass fabric is tiled on the mould, brushes resin compound, with rubber roll glass fabric is flattened;
By 25 layers of above-mentioned steps shops, glass fabric;
Cover mold, mould is put into baking oven;
Gradient type is heated;
The cooling cooling;
Die sinking.
The present invention is wave absorbing agent with the activated carbon fiber, along with the increase electrical conductivity of activated carbon fiber content rises gradually, and the absorbing property Changing Pattern basically identical of the Changing Pattern of electrical conductivity and material.
The specific embodiment
A kind of fiberglass moulding process comprises: the activated carbon fiber wave absorbing agent is added in the epoxy resin stir; Adding curing agent stirs; On mould, brush one deck resin wave permeation layer with brush; Glass fabric is tiled on the mould, brushes resin compound, with rubber roll glass fabric is flattened; By 25 layers of above-mentioned steps shops, glass fabric; Cover mold, mould is put into baking oven; Gradient type is heated; The cooling cooling; Die sinking.
