Polymer composite materials are preferred in many industrial areas because they are light,

durable and easy to process. While the polymer matrix holds the material together, the fibers

increase the durability of the material. Because these materials have different properties, it is

difficult to process the composites. Polyphenylene sulfide and its composites, which are

thermoplastic polymers at high temperatures, are frequently used in many areas from

transportation to energy sectors. The fiber reinforcements in the composite material increase

the durability and make it harder to heat treatment due to the different thermal properties.

Small dimples formed on the surface of the composite material and their geometry affects the

tribological properties of the material.

In this study, small dimples on 3.2 mm thick randomly oriented 40% short glass fiber

reinforced plates were formed. In the ablation process, 1064 nm wave laser with different

laser pulse energies was used. In this study, the effect of laser pulsing energy on the heat

affected zone (HAZ) on the composite material was investigated. Then, mathematical

modeling of the formation and propagation of the HAZ as a function of laser energy was
