Manufacturing of a composite part using out of autoclave prepregs
Krátký, Jan ; Gregor, Lukáš (referee) ; Kupčák, Radim (advisor)
This bachelor thesis deals with the production of a composite part using out-of-autoclave prepregs. The theoretical part describes composite materials, their properties and different manufacturing technologies with special emphasis on prepregs and the curing process. The practical part includes test specimen design, mould preparation, prepreg placement, lamination and curing. Three laminations were carried out using different technologies. The results show that the surface quality of the composite parts is significantly affected by the mould quality and curing pressure. Atmospheric pressure proved insufficient to achieve the desired surface quality of the moulded parts during vacuum pressing. The main conclusion of the paper is that off-autoclave technologies have the potential to produce high quality composite parts, but require further optimization of processes and materials.
