Determination of fracture toughness of propylene polymers at different operating temperatures
(Pergamon-elsevier Science Ltd, 2014-05-17)
The influence of the temperature on the fracture parameters of three types of polypropylenes under static loading conditions has been analyzed. Single-phase polypropylene homopolymer and random ethylene?propylene copolymer ...
Toughness distribution in complex PP/nanoclay injected mouldings
(Elsevier, 2013-01)
The fracture performance of PP–nanoclay box-like injection mouldings obtained in double gated mould and by direct compounding of PP and a PP-based masterbatch was studied. Samples were observed by polarised light microscopy ...
Non linear fracture mechanics of polymers: Load Separation and Normalization methods
(Pergamon-Elsevier Science Ltd, 2012-01)
Fracture toughness of ductile polymers can be measured by the incremental crack growth resistance curve, where J-Integral value is plotted as a function of crack extension. The determination of the resistance curve, J-R, ...
The effects of specimen size and testing conditions on fracture toughness evaluation of polypropylene homopolymer
(John Wiley & Sons Inc, 2007-04-07)
The results of an experimental test program performed to investigate the influenceof specimen dimensions and testing rate conditions on room temperature fracturetoughness of PP homopolymer are presented. The material ...
Effect of blend composition and related morphology on the quasi-static fracture performance of LLDPE/PP blends
(Elsevier, 2020-10)
In the present work, the effect of composition and related morphology on the fracture behavior of LLDPE/PP blends was thoroughly investigated. Fracture behaviors evaluated under quasi-static loading conditions and different ...
Mechanical evaluation of polylactic acid (PLA) based composites reinforced with different calcium phosphates
(Institute of Physics Publishing, 2018-08-31)
In the present work, the mechanical performance of polylactic acid (PLA) based composites reinforced with hydroxyapatite (HA) or β-tricalcium phosphate (β-TCP) was investigated. The polymer was melt compounded with 1 and ...
Changes in tribological performance of high molecular weight high density polyethylene induced by the addition of molybdenum disulphide particles
(Elsevier Science Sa, 2010-05-15)
Through this work, the effect of the addition of commercial molybdenum disulphide on the tribological behavior of high molecular weight high density polyethylene was assessed. Determination of several tribological parameters ...
Efficiency comparison of hyperbranched polymers as toughening agents for a one-part epoxy resin
(Cambridge Univ Press, 2015-03-28)
A previously synthesized hyperbranched poly(butylene adipate) (HPBA) polymer was compared with a commercial dendritic polyol (HPOH) as a toughening agent for a commercial one-part epoxy resin. Both modifiers were added in ...
