ABSTRACT

Carbon fibre reinforced polymer composites (CFRP) is one of the common materials used in machining by various manufacturing industries. The most persistent challenges during the machining, both concerning the consistency of machined surfaces and the properties of the material, are the difficulties such as fibre pull-out, delamination, and decomposition of the material matrix. This preliminary research highlights the laser machining of thick CFRP using a fibre laser of more than 1 kW. Laser machining experiments have been conducted to examine the ability of the fibre laser machine to cut thick CFRP through their high-quality laser beams. Based on the results, the study showed how the heat affected zone can be reduced when the higher cooling period is used. The effects of modulated beam mode include substantial reductions in HAZ compared with other experimental results. In all experimental attempts, substantial damage has occurred. The results are important in assessing the relationship between laser machining parameters and cutting results.

 

Keywords: Carbon fibre reinforced polymer composite (CFRP); heat-affected zone (HAZ); laser; machining parameters

 

ABSTRAK

Komposit polimer bertetulang gentian karbon (CFRP) adalah salah satu bahan popular yang digunakan oleh pelbagai industri pembuatan dalam operasi pemesinan. Kesukaran seperti penarikan serat, peleburan dan penguraian bahan matriks merupakan masalah berterusan yang sering berlaku semasa proses pemesinan dengan kedua-duanya mempengaruhi kualiti permukaan mesin dan sifat bahan. Penyelidikan awal ini menekankan pemesinan laser CFRP tebal dengan menggunakan lebih daripada 1 kW laser serat. Uji kaji pemesinan laser telah dilakukan untuk menilai kemampuan mesin laser serat untuk memotong CFRP tebal kerana kualiti pancaran lasernya yang unggul. Berdasarkan hasil kajian, sebuah parameter baru telah ditemukan, yang membuktikan pengurangan zon terjejas haba (HAZ) dengan ketara ketika waktu penyejukan yang lebih tinggi dikenakan. Penemuan mod balok yang dimodulasi optimis dibandingkan dengan hasil uji kaji lain dan HAZ dapat dikurangkan dengan ketara. Kerosakan besar telah berlaku dalam semua percubaan. Penemuan ini berguna dalam menggambarkan hubungan antara parameter pemesinan laser dan hasil pemotongan.
