Abstract

Thermoplastic part manufacture by laser-assisted automated tape placement (LATP) process has a high potential for the cost-effective production. Within the frames of this paper it was applied a designing of the industrial LATP process, i.e. planning of the experiments and on the basis of the plan matrix, the specimens were manufactured. Namely, two different thermoplastic prepreg materials were used: one based on polyphenylene sulfide and carbon fibers (PPS/CF) and other based on polyether ether ketone and carbon fibers (PEEK/CF). The planning of experiments was made separately for processing of these prepreg materials and as the most influenced factors were taken: laser temperature, compact pressure of roller and laser placement angle. The factors were changed on two levels: maximum and minimum, i.e. 23 factorial design was used. According to the plan matrix, eight experiments (composite samples) with LATR procedure were performed by varying the level of all three parameters.
For all manufactured specimens the flexural strength was tested and on the basis of the received experimental data it was created the regression equations which the best describes the processes. The regression equations showed that the temperature and the angle of laser placement significantly influence on the bending strength of the composite laminates. It was also found that there was an interaction between temperature and roller pressure which also affected the bending strength.
