G-10 Epoxy fiberglass sheet-G10 Insulation Material

G-10 is a fiberglass-reinforced epoxy composite material consisting of woven glass fibers and an epoxy resin adhesive. That is, made of woven fiberglass cloth impregnated with epoxy resin. There may be some variation in its performance parameters because different manufacturers and products may have different formulations and manufacturing processes.

As a glass fiber reinforced epoxy resin composite, G-10 has several advantages that make it widely used in a variety of applications. It has excellent insulation properties, mechanical strength and chemical corrosion resistance.

 

G-10 is a glass fiber reinforced epoxy resin composite material. Its manufacturing process mainly includes the following steps:

 

Material preparation:

 

Epoxy resin: Choose an appropriate epoxy resin as the base material, usually bisphenol A or bisphenol F epoxy resin.

Fiberglass Cloth: Choose fiberglass cloth or elongated fiberglass prepreg, which is a reinforcement material that provides strength and stiffness.

Stacking:

 

Layer by layer of fiberglass cloth pre-impregnated with epoxy resin. During this process, depending on the design and requirements, the orientation of the fiberglass cloth can be changed to adjust the properties of the final composite.

Typically a layer of epoxy is applied between each layer to ensure complete infiltration of the fiberglass and create an even layer structure.

Heat curing:

 

The laminated material is placed in a mold and then thermally cured. During this stage, the epoxy polymerizes to form a strong matrix.

Temperature and time control are critical to ensure that the resin is fully cured to achieve designed performance.

Cutting and processing:

 

Once heat curing is complete, the G-10 composite is removed from the mold, cut and machined. This can be achieved through mechanical processing (such as cutting, drilling, grinding) to meet the shape and size requirements of the final product.

Surface treatment:

 

 

Depending on the requirements of the final product, surface treatment may be required. This includes polishing, coating or other surface treatment processes to improve appearance quality and performance.

The entire manufacturing process requires strict control of material ratios, prepreg impregnation uniformity, temperature and time of the thermal curing process to ensure consistent performance and quality of the final G-10 product. This composite material is widely used in electronics, machinery, aerospace and other fields due to its high strength, excellent insulation properties and corrosion resistance.
