Assessment of Static Crack Resistance Behavior on Particulate Reinforced Composite for Solid Propellant

Design of Particulate-Reinforced Composite Materials

A microstructure-based model is developed to study the effective anisotropic properties (magnetic, dielectric or thermal) of two-phase particle-filled composites. The Green's function technique and the effective field method are used to theoretically derive the homogenized (averaged) properties for a representative volume element containing isolated inclusion and infinite, chain-structured part...

Fatigue Crack Growth in a Particulate TiB2-Reinforced Powder Metallurgy Iron-Based Composite

Fatigue crack growth behavior has been examined in a particulate titanium diboride (TiB2)–reinforced iron-based composite that had been produced via a mechanical alloying process. Comparison with equivalent unreinforced material indicated that fatigue crack growth resistance in the composite was superior to monolithic matrix material in the near-threshold regime. The composite exhibited relativ...

HTPB-Polyurethane: A Versatile Fuel Binder for Composite Solid Propellant

Development of Bone Particulate Reinforced Epoxy Composite For Biomedical Application

Mechanical properties of particulate goat bone reinforced epoxy composite were investigated in this research. This was aimed at assessing the suitability of the developed composites for biomedical applications. The combination of the two materials for the development of the composites was targeted to meet good surface compatibility in addition to the structural compatibility needed as biomateri...

Fatigue crack growth resistance in SiC particulate and whisker reinforced P/M 2124 aluminum matrix composites

Fatigue crack growth is examined in P/M 2124 aluminum alloys reinforced with SiC particles (SiCp) and whiskers (SiCw) over a wide spectrum of growth rates from 10 to 10 m per cycle. Effects of aging treatment, orientation of crack growth direction with respect to the rolling direction, mean stress (or stress ratio), and reinforcement volume percent on the fatigue crack growth threshold are inve...
