Can glass fiber reinforced plastics be machined with high precision?
Matters needing attention(1) because the mechanical properties of glass fiber products are brittle and brittle, it is difficult to clamp. The clamping force causes the workpiece to deform or block the workpiece, and the excessive force will cause the workpiece to fly off.(2) because of the glass fiber heat is relatively poor, linear expansion into relatively large, the workpiece is easy to deform, the size is more difficult to control.(3) the best data can be obtained only through process experiments.
The mechanical processing of glass fiber reinforced plastics is quite possible.(1) the tool can be made of high speed steel or tungsten carbide of fine particle, because of hard alloy. If the amount is large, the requirements are relatively high, you can use artificial diamond (PCD) cutting tools.(2) the selection of machine tools depends mainly on the machining accuracy of your products. As you require 0.01 mm precision, the machine tool accuracy should be within 0.005 millimeters. Otherwise, how can we meet the requirements?
The so-called glass fiber reinforced plastic (FRP), also known as GRP, that is, fiber reinforced plastics.(1) generally refers to the use of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics made from glass fiber or its products are referred to as glass fiber reinforced plastics or glass fiber reinforced plastics.(2) because of the variety of resin used, it is called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic resin glass fiber reinforced plastics. Light and hard, non conductive, high mechanical strength, less recycling, corrosion resistance. It can be used instead of steel to make machine parts, automobiles, ship shells, etc..
