Forming of thin-walled profiles made of FML in autoclave process

Purpose The purpose of the study was to develop the forming methodology for FML laminates with complex shapes, based on aluminium and epoxy – glass composite. Design/methodology/approach The subject of research encompassed Al/GFRP fibre metal laminates. Autoclave process has been selected for FML profiles production. Manufacturing process was followed by quality analysis for laminates produced. Findings The achievement of high stability and dimensional tolerance of thin - walled FML laminates is ensured by developed technology. The values of selected sections angles are significantly limited as a result of forming of FML laminates through the components performing. Failure to adhere to technological recommendations and to high regime of developer technology may lead to the occurrence of defects in FML. Practical implications Thin-walled composite structures could be applied in light weight constructions, such as aircraft structures, which must meet rigorous requirements with regard to operation under comp...
