Abstract In this study, a technique to predict the equivalent initial crack size (EICS) in a particulate composite material, containing hard particles embedded in a rubber matrix, was developed using constant strain rate crack propagation test data. The accuracy of the developed technique was determined. In addition, the statistical distribution of the equivalent initial crack size follows the second asymptotic distribution of maximum value.

Particulate Composite Material

In this study, the effect of constraint on the critical Mode I stress intensity factor for the onset of crack growth was investigated in a particulate composite material, containing hard particles in a rubbery matrix. Uniaxial specimens with different specimen thicknesses and initial crack lengths were tested under a constant strain rate of 8 cm/cm/min at room temperature. The tested data was analyzed and the results are discussed.

ABSTRACTIn the present study a new sandwich laminate is designed and mechanically characterized. The laminate is elaborated with a core of particulate composite material consisting of recycled material from milk and juice cartons (multilayer laminate of Tetra Brik®), and HDPE containers from Urban Solid Waste (USW). The elaborated material consists of aluminum facings with a particulate core, consolidated with a thermoplastic adhesive of polypropylene- maleic anhydride. The main properties under tension are evaluated under testing standards. Results show good compatibility in the union of elements, with potential applications in building facades and false walls for the construction and furnishing industries.
