Abstract: The paper presents a study of E-glass reinforced Inorganic Phosphate Cement (IPC) matrix composites. Three types of textile reinforcement made in E-glass fibers were considered: unidirectional roving, chopped strand mat (CSM) and unidirectional fabric. Four types of composite were developed, using different reinforcement combinations, but also diverse manufacturing processes: hand lay-up, pultrusion, pultrusion/compression molding.
These processes allowed to obtain fiber volume ratios ranging from 15% to 27%. Specimens obtained from these products were cut out and tested in tension, compression and shear, in order to obtain the constitutive equations. The experimental results are confronted with several analytical models found in the literature, allowing to propose adapted formulae for the predictive behavior of the composites. Furthermore, inclined tensile and compression tests, ranging from 0° to 90°, were developed in order to establish failure envelopes. The combination of two failure criteria (Tsai-Wu, Mohr-Coulomb) allows to define correctly the working domain of the composite material.
