Single point incremental forming of polyamide/30 wt% short glass fiber composite

The experimental study of single point incremental forming (SPIF) of a thermoplastic matrix composite (TMC) was presented in this research. The TMC's matrix was built of polyamide (PA) 6.6, and the reinforcement was 30 wt percent short glass fiber (GF). The TMC was manufactured by hot pressing PA/30 wt percent GF granules to a thickness of 1.5 mm. The impact of SPIF process variables such as forming temperature (60 degrees C-120 degrees C), spindle speed (500 rpm-3000 rpm), wall angle (30 degrees-60 degrees), and step size (0.5 mm-1.5 mm) on forming depth and shrinkage owing to cooling were investigated. The findings revealed that the wall angle is the most effective parameter on TMC forming depth and shrinkage. Furthermore, TMC showed a significant percentage of shrinkage when it is cooled (up to 83.6% of shrinkage).

Automated summary

The experimental study focuses on the single point incremental forming process of a thermoplastic matrix composite and investigates the effects of process variables on forming depth and shrinkage. The findings highlight the significant influence of wall angle on the forming depth and shrinkage of the composite material.
