A novel method is proposed to create a TBC on the CFRP/epoxy laminate surface in a single technological process by formation of one additional layer made of a commercially available alumina fiber mat. Both materials: the CFRP/epoxy laminate made of four layers and the ceramic mat were joined during prepreg curing.
The quick thermal heating tests of the TBC system were conducted for different times with a propane-butane torch. Changes of material strains due to temperature influence are determined experimentally in uniaxial tensile tests via the Digital Image Correlation (DIC) method. A numerical model corresponding to the experimental quick heating test is built in Abaqus standard finite element software to determine temperature distribution in the CFRP/epoxy laminate.
The experimental and numerical investigations lead to a conclusion that the alumina fiber mat is an effective protection of the CFRP/epoxy laminate against temperature degradation and can be used in industrial practice.
