Reinforced parts are usually the functional components of heavy-duty products and made of semi-crystalline plastics like PA6+GF, PA66+GF, PET+GF or PBT+GF.
Amorphous plastics with reinforcements, such as PC+GF is sometimes used in boxes that require, in addition to impact resistance, extremely high strength.
The most common reinforcement by far is glass fiber. Carbon fiber is an attractive filler, but considerably costlier than glass and therefore usually used in high-end applications only.
In this section, you can find the following reinforced engineering plastics:
