Microstructure-property relationships in alumina trihydrate filled poly (methyl methacrylate) composite materials

摘要

The mechanical properties (Young's modulus and fracture toughness) of composite made from a poly (methyl methacrylate) (PMMA) matrix filled with alumina trihydrate (ATH) are reported. The experiments were performed using flexural tests and single edge notched bend (SENB) tests. The composites samples were tested at a range of filler volume fractions (34.7%, 39.4% and 44.4%) and mean filler diameters (8 μm, 15 μm and 25 μm). The data of Young's modulus agreed well with the results of Lielens model and finite element analysis (FEA) model.
