Characterization of cure of carbon/epoxy prepreg used in aerospace field
(2005-07-01)
Carbon/epoxy 8552 prepreg is a thermoplastic toughened high-performance epoxy being used in the manufacture of advanced army material. Understanding the cure behavior of a thermosetting system is essential in the development ...
The effect of epoxy excess on the kinetics of an epoxy-anhydride system
(John Wiley & Sons Inc, 2002-09)
The uncatalyzed cure of a commercial tetrafunctional epoxy monomer TGDDM (N,N,N′,N′-tetraglycidyl-4,4′-diaminodiphenylmethane) with hexahydrophthalic anhydride (HHPA), using variable stoichiometric ratios is reported. The ...
Epoxy/anhydride networks modified by epoxy/anhydride oligomers containing SiOH groups
(John Wiley & Sons Inc, 2000-02-07)
Epoxy/anhydride oligomers containing variable amounts of trialkoxysilane groups were synthesized from phenyl glycidyl ether (PGE), 3-glycidoxypropyl trimethoxysilane (GPMS), and methyl tetrahydrophthalic anhydride (MTHPA), ...
Improving the dispersion and flexural strength of multiwalled carbon nanotubes–stiff epoxy composites through β-hydroxyester surface functionalization coupled with the anionic homopolymerization of the epoxy matrix
(Pergamon-Elsevier Science Ltd, 2006-10)
Multiwalled carbon nanotubes (MWNTs) were functionalized in a two-step acid-epoxy functionalization process, in which suitable surface condition and reactivity compatible with the DGEBA epoxy resin was introduced. The use ...
Modeling of dynamic mechanical properties of epoxy and epoxy-phenolic reinforced with multi wall-carbon nanotubes
(Sage Publications, 2014-06)
The viscoelastic properties of nanocomposites based on epoxy and epoxy-phenolic blend matrix reinforced with multi wall-carbon nanotubes were studied. It was varied the content of carbon nanotube (0.2 and 0.5 wt.%) and ...
Olive Cellulosic Fibre Based Epoxy Composites: Thermal and Dynamic Mechanical Properties
(2022-01-01)
This study deals with the evaluation of the impact of three different olive tree residues: olive tree small branch (OTS), olive tree big brunch (OTB) and olive tree leaves (OTL) as a filler on thermal properties of olive/epoxy ...
Damping behavior of hygrothermally conditioned carbon fiber/epoxy laminates
(2007-12-05)
Carbon fiber reinforced polymer composites have been used in wide variety of applications including, aerospace, marine, sporting equipment as well as in the defense sector due to their outstanding properties at low density. ...
Epoxy-urethane copolymers: Relation between morphology and properties
(Wiley, 2001-09-20)
The modification of an amine-cured epoxy resin by the addition of polyurethanes (PU) was investigated, and their mechanical and impact properties were related to their microstructure and morphology. For the study, two ...
Flexural performance of concrete beams reinforced with epoxy resin/glass and carbon fibers composites
(2021-01-01)
Factors such as project and execution errors, lack of maintenance and inspection, and increases in loading can cause deficiencies to reinforced concrete structures. In this regard, there is the necessity of the application ...
