Abstract

Poly(ether-ether-ketone) (PEEK) is used in many area especially structural and industrial applications due to it has superior mechanical, chemical and thermal prop- erties. Besides excellent electrical and thermal properties, carbon bres have high specic tensile modulus and strength. Due to these properties, carbon bers are frequently used as reinforcement materials in polymer matrices. While the polymer matrix determines the long-term durability of the composite system, light carbon bers ensure that the material is durable and lightweight. Since composites have more than one materials together which are dierent thermal and mechanical properties, machining of compos- ites 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 eects of the laser energy on temperature distribution in PEEK composite was investigated and the numerical model was obtained.
