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
