Özet

Poly(ether-ether-ketone) (PEEK) is used in many area especially structural and

industrial applications due to the fact that it has superior mechanical, chemical and

thermal properties [1]. Besides excellent electrical and thermal properties, carbon

fibres have high specific tensile modulus and strength [2]. Due to these properties,

carbon fibers are frequently used as reinforcement materials in polymer matrices.

While the polymer matrix determines the long-term durability of the composite

system, light carbon fibers ensure that the material is durable and lightweight. The

polymeric matrix also contributes to damage resistance and interlaminar shear

strength [3].

Since composites have more than one materials together which are different

thermal and mechanical properties, machining of composites is more complex than

pure materials. Lasers are used in many industrial and high technological area.

In this study, proposed mathematical model has been applied on the cavity

formation on PEEK composite by single laser pulse using Fourier method with

homogenous approach. The effects of the laser energy on temperature distribution in

PEEK composite was investigated and the numerical model was obtained. Under

some natural regularity and consistency conditions on the input data, the existence,

uniqueness of solution are shown by using the generalized Fourier method.

Finally, the experimental data are compared to the results calculated by heat

conduction models.
