MICRO-MOULDING OF CERAMIC STRUCTURES USING CERAMIC-PRECURSOR POLYMERS

Jürgen Brugger, Vahid Fakhfouri

We develop ceramic structures using ceramic-precursor polymers. The possibility to modify easily the physical properties of the final ceramic structures just by doping the precursor with nanoparticles, makes them interesting for new MEMS and NEMS developme ...

Nanoceramic composites: Tough to test

William Curtin

Ceramic composites reinforced with nanoscale materials such as nanotubes are widely expected to have superior mechanical properties compared with more conventional composite materials. However, new work shows that the toughness of these nanocomposites can ...

Stress rupture in ceramic-matrix composites: Theory and experiment

William Curtin

A micromechanically based model for the deformation, strength, and stress-rupture life of a ceramic-matrix composite is developed for materials that do not degrade by oxidative attack. The rupture model for a unidirectional composite incorporates fiber-str ...

Failure of crossply ceramic-matrix composites

William Curtin

The fast-fracture and stress-rupture of a crossply ceramic-matrix composite with a matrix through-crack are examined numerically to assess the importance of fiber architecture and the associated stress concentrations at the 0/90 ply interface on failure. F ...

Green's function vs. shear-lag models of damage and failure in fiber composites

William Curtin

A Green's function method (GFM) for simulating fiber damage evolution and tensile strength in fiber-reinforced composites is compared in detail to the predictions of the standard shear-lag model (SLM) widely used in the literature. The GFM extracts the in- ...

Multiscale modeling of damage and failure in aluminum-matrix composites

William Curtin

A multiscale approach to composite failure, in which detailed information on small-scale micromechanics is incorporated approximately yet accurately into larger-scale models capable of simulating extensive damage evolution and ultimate failure, is applied ...

Design of fiber/coating systems for high strength in ceramic matrix composites

William Curtin

A finite element model is used to study the stresses arising in ceramic matrix composites with different coatings and sliding interfaces. Stress concentrations in the fibers are found near matrix cracks, and their magnitudes depend on the location of the d ...

Tough-to-brittle transitions in ceramic-matrix composites with increasing interfacial shear stress

William Curtin

The possibility of decreasing ultimate tensile strength associated with increasing fiber/matrix interfacial sliding is investigated in ceramic-matrix composites. An axisymmetric finite-element model is used to calculate axial fiber stresses versus radial p ...

Tensile strength of fiber-reinforced composites: II. Application to polymer matrix composites

William Curtin

An analytic model for predicting the tensile strength of uniaxial fiber-reinforced composites is applied to several different graphite-fiber composites and shows good agreement with measured strengths. The model includes the effects of fiber statistical st ...
