In contrast to most other building materials the strength of glass is not a material parameter, but rather a combination of the material treatment and the load position effects. Structural glass elements are produced with heat treatment when compressive re ...

Experimentation on adhesion of epoxy

Alain Curnier, Aleksandar Sekulic

In a recent article (Sekulic and Curnier (2007) [1]), an original axisymmetric epoxy-stamp on glass-disc specimen, which exhibits stable debonding, was presented for identifying the adhesive properties between epoxy and glass, namely interface debonding en ...

In the last two decades architectural glass has made an enormous leap from a secondary material to a material that combines structural and cladding roles. The structural role is a new and problematic one. In contrast to most other engineering materials the ...

The aim of this study has been to develop processing techniques for novel bioresorbable thermoplastic cellular composites, reinforced with continuous inorganic fibres, for use as biodegradable scaffolds for bone tissue engineering. As the implanted composi ...

Cellular composites based on continuous fibres and bioresorbable polymers

Pierre-Etienne Bourban

Biocompatible composites, whose porosity and fibre fraction call be tailored over a large range and whose mechanical resistance is comparable to that Of natural bone, were processed with poly(lactic acid) (PLA) and continuous glass fibres. The processing s ...

Bone tissue engineering aims at developing scaffolds, or porous structures, as supports for cell migration, proliferation and differentiation, in order to favor bone healing. L-poly lactic acid (PLA) foams, which were reinforced or not with β-tricalcium ph ...

Polylactic Acid–Phosphate Glass Composite Foams as Scaffolds for Bone Tissue Engineering

Dominique Pioletti, Pierre-Etienne Bourban

Phosphate glass (PG) of the composition 0.46(CaO)–0.04(Na2O)–0.5(P2O5) was used as filler in poly-L-lactic acid (PLA) foams developed as degradable scaffolds for bone tissue engineering. The effect of PG on PLA was assessed both in bulk and porous composit ...

2006

Bone is a complex porous composite structure with specific characteristics such as viscoelasticity and anisotropy, both in morphology and mechanical properties. Bone defects are regularly filled with artificial tissue grafts, which should ideally have prop ...

For centuries, the use of glass in buildings was essentially restricted to functions such as windows and glazing. Over the last decades, continuous improvements in production and refining technologies have enabled glass elements to carry more substantial s ...

The aim of this investigation was to test the biocompatibility of three-dimensional bioresorbable foams made of poly(L-lactic acid) (PLA), alone or filled with hydroxyapatite (HA) or beta-tricalcium phosphate (beta-TCP), with human primary osteoblasts, usi ...
