Glass fiber reinforced plastic is based on the original pure plastic, glass fiber and other additives, thereby increasing the use of materials.
In general, most of the glass fiber reinforced materials used in structural parts of the product is a structural engineering materials; such as: PP ABS PA66 PA6 PC POM PPO PET PBT PPS
advantage:
1. After glass fiber reinforced glass fiber is a high temperature resistant material, therefore, enhance the heat resistance of plastic temperature than before without much increase, especially nylon plastic;
2. After the glass fiber reinforced, due to the addition of glass fiber, which limits the mutual movement between the plastic polymer chains, therefore, shrinkage reduction of reinforced plastics is much lower and the rigidity is greatly improved.
3. After the glass fiber reinforced, reinforced plastic will not stress cracking, at the same time, plastic impact performance improved a lot;
Glass fiber reinforced glass fiber is a high strength material, which also greatly enhanced the plastic strength, such as: tensile strength, compressive strength, bending strength, improved a lot;
5. After glass fiber reinforced, due to the addition of glass fiber and other additives, enhance the combustion performance of plastics decreased a lot, most of the material can not be ignited, is a fire-retardant material.
Disadvantages:
1. Glass fiber reinforced later, due to the addition of glass fiber, without glass fiber is transparent, will become opaque;
2. After the glass fiber reinforced, all the plastic to reduce the toughness, and increased brittleness;
3. Glass fiber reinforced, due to the addition of glass fiber, all materials melt viscosity increases, poor fluidity, injection pressure than without glass to increase a lot;
4. Glass fiber reinforced, due to the addition of glass fiber, poor fluidity, in order to normal injection, all enhanced plastic injection temperature than before without glass fiber increased 10 ℃ -30 ℃;
5. After the glass fiber reinforced, due to the addition of glass fiber and additives to enhance the hygroscopic plastic greatly enhanced the original pure non-absorbent will also become absorbent, therefore, have to enter the drying injection.
