Composites made from lignocellulosics and thermoset polymers
(Gordon Breach Publishing, 2006-09-24)
Composites made from a stryrene/unsaturated polyester thermoset matrix and woodflours from different wood species have been prepared and tested. Pine (Pino Eliottis), eucaliptus (Eucaliptus Saligna) and marmelero (Ruprechia ...
Natural composites: polymeric matrices based on vegetable resources
(Taylor & Francis, 2006-07-01)
The aim of this work has been to develop new composites using filler and resins obtained from renewable resources, combining low cost and good mechanical properties. The raw materials selected for the polymeric matrix were ...
Modified woodflour as thermoset fillers Part I. Effect of the chemical modification and percentage of filler on the mechanical properties
(Elsevier, 2001-12)
Composites made from an unsaturated polyester/styrene thermoset matrix and esterified woodflour have been prepared and tested. Different degrees of esterification of the wood particles with maleic anhydride were obtained ...
Influence of investment granulometry on the castability and surface roughness of castings obtained with Ni/Cr alloys
(ABM, ABC, ABPol, 2009)
The aim of this study was to verify the influence of investment granulometry on the castability and surface roughness of Ni/Cr castings. Four investments were selected for casting according to decreasing order of granulometry: ...
Biosynthesis and characterization of biodegradable Poly(3-hydroxybutyrate) from renewable sources
(UNIV FED RIO DE JANEIRO, LAB HIDROGENIO, 2008)
Poly(3-hydroxybutyrate) was produced in fed-batch cultures of Ralstonia eutropha DSM 428 and Alcaligenes latus ATCC 29712 on a mineral medium with different carbon sources such as sucrose, sodium lactate, lactic acid, ...
FT-Raman investigation of biodegradable polymers: Poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate)
(ELSEVIER SCIENCE BV, 2010)
This work presents a FT-Raman study (lambda(0) = 1064 nm) of naturally occurring polyester poly[(R)-3-hydroxybutyrate] (PHB) and its copolymer poly[(R)-3-hydroxybutyrate-co-(R)-3-hydroxyvalerate] (PHBV) with 5,8 and 12 mol ...
Constitutive models for biodegradable thermoplastic ropes for ligament repair
(ELSEVIER SCI LTDOXFORD, 2013-08-02)
The concept behind a biodegradable ligament device is to temporarily replace the biomechanical functions of the ruptured ligament, while it progressively regenerates its capacities. However, there is a lack of methods to ...
KDP/PEDOT: PSS mixture as a new alternative in the fabrication of pressure sensing devices
(ELSEVIER SCIENCE BV, 2008)
In this work we studied the mixture of poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS), a commercial polymer, with monobasic potassium phosphate (KDP), a piezoelectric salt, as a possible novel material ...
Effect of bituminous impregnation on nonwoven geotextiles tensile and permeability properties
(ELSEVIER SCI LTD, 2011)
Geosynthetics interlayer systems are effective techniques to control reflective cracking in damaged pavements. It comprises the inclusion of nonwoven geotextiles between the damaged layer and the new overlay of the pavement ...
