High temperature resistant epoxy insulating board processing Yellow epoxy resin insulation board.
Epoxy plate (FR - 4)
Description: glass fiber cloth made of epoxy resin adhesive heating pressure, high mechanical performance
under medium temperature, stable electrical performance under high humidity.Applicable to mechanical,
electrical and electronics with high insulation structure parts and components, has high mechanical and
dielectric properties of good heat resistance and wave resistance.Heat-resistant grade F (155 degrees), specifications, thickness: 0.5 to 100 mm, under the condition of high
temperature of 180 ℃ heat deformation, is generally not and other metal in a heated, may cause the
deformation of sheet metal.
Purpose
Motor, electrical equipment for insulation structure parts, including the style of the switch, electrical
insulation, FPC reinforcement plate, carbon film printed circuit boards, computer drilling with pad, mould,
fixture, etc.(PCB test frame) and can be used in damp environment condition and the transformer oil, has
extensive application.

Carbon fiber winding of molding process
Winding molding process is soaked in resin adhesive solution of continuous fiber (or cloth belt, presoak
yarn) on winding to the mandrel according to certain rules, and then after curing, demoulding, obtain
products.According to the filament winding forming physical and chemical condition when the resin is
different, divided into dry winding, wet winding and half dry winding 3 kinds.(1) dry winding Dry winding is
adopted through presoak rubber processing presoak yarn or, on a winding machine after soften to viscous
flow winding onto the mandrel.Because of presoak yarn (or with) is a professional production, to strictly
control the resin content (accurate to 2%) and presoak yarn quality.Therefore, dry winding can accurately
control the quality of the product.Dry winding process is the biggest characteristic of high production
efficiency, winding speed can reach 100 ~ 100 m/min, winding machine cleaning, labor health condition is
good, high product quality.The downside is winding equipment is expensive, need to increase in yarn
manufacturing equipment, so the investment is bigger also, dry low interlaminar shear strength of winding
products.
