Educational Goals

This course will address the fundamentals of thermoplastic composites or “filled” plastics. Topics to be addressed include: formulation, filler size, and surface chemistry for optimized interaction with the polymer and characterization techniques as well as unique aspects of part design and processing that are important for filled thermoplastics. The importance of filler aspect ratio and the resulting orientation with polymer flow is emphasized. A demo of twin-screw compounding also will take place, where participants can observe the influence of compounding variables on composite quality.

Who Should Attend

Anyone who processes, designs, or uses plastic parts that contain glass, carbon, or mineral fillers will benefit from this course. Among those who can benefit from this one-day workshop are process and project engineers, quality engineers, manufacturing engineers, part designers, and anyone involved in the material selection process.
