Out-of-autoclave molding of carbon fiber composites pipes with interlaminar carbon nanotubes
Materials Research Proceedings, 2023 Abstract. Carbon fiber reinforced (CFR) composite rings with and without interlaminar carbon nanotubes (I-CNTs) were manufactured starting from high performance prepregs used in aeronautics. Nano-particles deposition was obtained by an innovative easily scalable procedure which does not affect composite processability.

The Stacking Action in Autoclave Molding and a Process Judgment Analysis of the Worker
Procedia Manufacturing, 2015 AbstractThree-dimensional components which incorporate CFRP are molded by skilled workers manually; this makes quality control difficult. This study discusses how workers’ skill influences the mechanical performance of molded products. This study aims to establish qualification criteria and standardize the manufacturing process.

Thickness Control of Autoclave-Molded Composite Laminates
Journal of Manufacturing Science and Engineering, 2023 Abstract Composite materials and especially those made from pre-impregnated (prepreg) material are widely used in the aerospace industry. To achieve the tight assembly dimensional tolerances required, manufacturers rely on additional manufacturing steps like shimming or machining, which generate extra waste, which are time-consuming and ...
