The most important reasons for the fact that polymer composite materials are the preferred
material in many industrial fields are that they are durable, light and easy to process. The
durability of the composite materials is due to the fiber material. Polyphenylene sulfide is a
high-temperature, thermoplastic polymer. PPS and its reinforced composites having excellent
strength, high modulus, fatigue resistance, and high strength-to-weight ratio are used at
numerous applications from transportation to energy sectors. Fiber enhancers in composite
material increase durability, making it harder to heat treatment. The main purpose of this
study is to create cavities in ideal geometries to improve the tribological properties of the
polyphenylene sulphide (PPS) composite surface.
Small cavities were formed on 3.2 mm thick, randomly oriented 40% short glass fiber
reinforced plates. GSI lumonics JK760TR Series Laser with 1064 nm wavelength (Class 4)
with different laser pulse times was used in ablation. In this study, the effect of laser pulse
duration on Heat Affected Zone in Fiber Reinforced Polyphenylene Sulphide was
investigated. Then, mathematical modeling of the formation and propagation of the Heat
Affected Zone (HAZ) was made.
