Biodegradation of composite materials
International Biodeterioration & Biodegradation, 1996Fiber-reinforced polymer composites were examined for susceptibility to microbiologically-influenced degradation. Composites, resins, and fibers were exposed to sulfur/iron-oxidizing, calcareous-depositing, ammonium-producing, hydrogen-producing, and sulfate-reducing bacteria (SRB) in batch culture.

Kenaf reinforced biodegradable composite
Composites Science and Technology, 2003Abstract Mechanical properties of environmentally friendly composite made of kenaf fibre and poly- l -lactic acid (PLLA) resin was investigated. Young's modulus (6.3 GPa) and the tensile strength (62 MPa) of the kenaf/PLLA composite (fibre content=70 vol.%) were comparable to those of traditional composites. These properties were higher than those of

Composite biodegradable materials based on polyhydroxyalkanoate
Applied Biochemistry and Microbiology, 2010Conditions for the processing and mixing of biodegradable polymers at temperatures less than their thermal destruction (130-150 degrees C) using standard equipment have been identified. The structure of the polyhydroxybutyrate/valerate (PHB/V) copolymer has been revealed and peculiarities of the crystal phase formation at different monomer ratios have ...

Biodegradable composites with aligned hydroxyapatite nanoneedles
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2012AbstractWe prepared an anisotropic bone graft composite to mimic the hierarchical structure of the natural bone in which aligned hydroxyapatite (HA) nanocrystals deposit along collagen fibers. To approach the modulus and strength of the bone, we incorporated synthesized HA nanoneedles and melt drawn poly(L‐lactic acid) fibers in our composite as ...
