What are phenylpropanolimine composites with 10% chopped carbon fiber reinforced?

PPA CF10 refers to a composite material that combines Polyphthalamide (PPA) with 10% carbon fiber reinforcement. This blend enhances the mechanical properties of PPA, making it suitable for applications requiring high strength, stiffness, and thermal stability. To understand it comprehensively, let’s delve into its composition, properties, manufacturing processes, applications, and advantages.

Composition and Structure

this compound consists of:

1. Polyphthalamide (PPA):
– PPA is an engineering thermoplastic known for its high mechanical strength, stiffness, and resistance to heat and chemicals.
– It offers good dimensional stability and can withstand temperatures typically up to around 200°C (392°F), depending on the specific grade.

2. Carbon Fiber Reinforcement:
– Carbon fibers are lightweight, extremely strong materials derived from precursors like polyacrylonitrile (PAN).
– Incorporating carbon fibers into PPA enhances the composite’s mechanical properties significantly, including tensile strength, stiffness, and fatigue resistance.

Properties of PPA CF10

PPA CF10 exhibits several key properties:
