Investigation of the Possibilities to Obtain Integral Sandwich Constructions

Abstract

Present paper shows the possibility of obtaining complex planar integral sandwichconstructions for one technological transition The technology of obtaining integrated sandwichconstructions is described. The data of flexural strength tests of the samples obtained by the methodof VaRTM and hand lay-up molding are presented. It has been established that samples obtained bythe VaRTM method are 13% stronger. The obtained data are also confirmed by microscopicresearch. Fiberglass of integral sandwich constructions made by hand lay-up molding ischaracterized by significant porosity.
