Özet

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.
