1) Process difference
Glass fiber: Glass fiber is an inorganic non-metallic material with excellent performance.
It is made by melting glass materials (quartz sand, alumina and pyrophyllite, limestone, dolomite, boric acid, soda ash, Glauber's salt, fluorite, etc.) at high temperature, then drawing, winding, and woven into glass fiber cloth , and then according to the design of the product, it is shaped for the final appearance. The diameter of a single fiber is usually several microns to more than 20 microns.
It is made of carbon fiber pressed and woven by graphite, and the carbon content is usually more than 90%. After the same process of wire drawing, winding weaving, etc., the carbon fiber cloth is finally wrapped into the finished product with a mold layer by layer, and epoxy resin is used. The resin is cured.
2)Functional difference
Glass fiber: The advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but the disadvantages are brittleness and poor wear resistance.
Carbon fiber: Carbon fiber has many excellent properties. Carbon fiber has high axial strength and modulus, low density, high specific performance, no creep, ultra-high temperature resistance in non-oxidizing environment, good fatigue resistance, specific heat and electrical conductivity between Between metal and metal, the thermal expansion coefficient is small and anisotropic, the corrosion resistance is good, and the X-ray transmittance is good. Good electrical and thermal conductivity, good electromagnetic shielding, etc.
3)Differences in use
Glass fiber: The roving is made up of parallel strands or parallel monofilaments. Plaid is a non-twisted roving plain weave fabric, which is an important base material for hand-laid glass fiber reinforced plastic. Fiberglass mats, milled fibers, fiberglass fabrics, combined fiberglass.
Carbon fiber: Carbon fiber carbon materials have been widely used in various fields of military and civilian industries. From civil industries such as aerospace, aviation, automobiles, electronics, machinery, chemicals, and textiles to sports equipment and leisure products.
Carbon fiber reinforced composite materials can be used in military fields such as aircraft manufacturing, industrial fields such as wind power blades, electromagnetic shielding and antistatic materials, body substitute materials such as artificial ligaments, and in the manufacture of rocket shells, motor boats, industrial robots, and automotive leaf springs. drive shaft, etc. Sports fields such as baseball and bat. Carbon fiber is a typical new industrial material in high-tech fields.
