Abstract: Carbon foam is a new functional and structural material with characteristics like high specific strength and adjustable conductivity and thermal conductivity, which has wide application prospect in carbon foam-based polymer matrix composites tooling manufacturing. In this work, the damage process of carbon foam sandwich structure with carbon fiber reinforced composites (CFRP) under quasi-static transverse indentation was studied experimentally, and the failure criterion applicable to transversely isotropic carbon foam was proposed. Finite element models of sandwich structure without considering the adhesive penetration area and considering the penetration area were established respectively. The effectiveness of the model was verified by the test results, and the influence of relevant parameters was further discussed. The results show that the sandwich structure mainly occurs the compression and shear failure of carbon foam, and the matrix crack and delamination of top face sheet. The damage process consists of carbon foam collapsing, carbon foam 45° or vertical cracking and carbon foam-face sheets separating accompanied by matrix cracking and the delamination of top face sheet. Compared with the damage morphologies of PMI foam and aluminium foam, there are several random cracks in the carbon foam. The finite element models meet the analysis accuracy requirements, and the numerical prediction of damage process shows good agreement with experimental results. The further analysis shows the greater the thickness of carbon foam and face sheets are, the more quasi-static indentation energy and the greater peak force, and the diameter of indenter and the thickness of adhesive have no obvious relationship with quasi-static indentation energy and peak force. Face sheets with ±45° layups can improve quasi-static indentation energy of the sandwich structure effectively.
