A novel approach for developing boron carbide (B4C)/cyanate ester (CE) co-continuous Functionally Graded Materials (FGMs) with eliminated abrupt interfaces

Although traditional functionally graded materials (FGMs) have weakened a certain extent abrupt changes along interfaces between layers, eliminating residual abrupt interfaces which results in great inter laminar stresses remains a major challenge. Herein, ceramic scaffolds with novel continuously graded channels have been firstly prepared through combining layer-by-layer casting with gelation-freeze-dry. Followed by infiltrating soft phase, the...
