Eye Movement Influence of Stacking Worker in Autoclave Molding

Volume 4B: Dynamics, Vibration, and Control, 2015
Three-dimensional components which incorporate CFRP are molded by skilled workers manually. This makes quality control difficult. In this study, we aim to establish standardization of work and set a standard of quality examination. We focus on the eye movement to examine that the differences of worker’s proficiency level influence on the hand lay-up ...

OUT-OF-AUTOCLAVE MOLDING OF THICK CARBON FIBER REINFORCED TUBES BY USING SHRINKABLE TUBES

SAMPE 2025 Technical Proceedings
Carbon fiber reinforced (CFR) tubes for aeronautic and aerospace are manufactured by wrapping and autoclave curing. These technologies present technological and cost barriers for the automotive and urban air mobility (UAM) sectors. Autoclave molding is an expensive process because of the time, energy and materials involved.

The investigation of technological parameters of autoclave molding of parts made from polymer composite materials

Polymer Science Series D, 2014
Results of the investigation of the process of removal of excess binder from samples with different numbers of prepreg layers during autoclave molding of fiberglass under vacuum are presented. It has been demonstrated that, during calculation of excess binder, consideration must be given to its viscosity and pot life, as well as the thickness of the ...
