Repair of composites: Effect of laser and different surface treatments
(Elsevier B.V., 2015-06-01)
Objectives: This study investigated the repairs of resin composite restorations after using different surface treatments.Design: Eighty four truncated cones of Filtek Z350 were prepared and thermo-cycled (20,000 cycles). ...
Rheological, thermal and mechanical characterization of fly ash-thermoplastic composites with different coupling agents
(Wiley, 2010-09)
Composite materials were prepared by mixing fly ash obtained from biomass combustion as filler and isotactic polypropylene (PP) as matrix. Three silane-type coupling agents mainly differing in the size of their functional ...
Deformation and fracture behavior of PP/ash composites
(Taylor & Francis, 2009-12)
In the present work, the deformation and fracture behavior of PP/ash composites with different ash content was investigated. The effect of a silane coupling agent was also analyzed. From uniaxial tensile tests, an increase ...
Effect of sawdust surface treatment and compatibilizer addition on mechanical behavior, morphology, and moisture uptake of polypropylene/sawdust composites
(2010)
Polypropylene/sawdust composites were investigated to assess the effect of sawdust surface treatment and compatibilizer addition on polymer/fiber adhesion. Two silane coupling agents were used for sawdust surface treatment: ...
Effect of methacryloyloxydecyl dihydrogen phosphate–containing silane and adhesive used alone or in combination on the bond strength and chemical interaction with zirconia ceramics under thermal aging
(Operative Dentistry Inc, Indiana Univ School Dentistry, 2020)
Objectives: To evaluate the effect of a methacryloyloxydecyl dihydrogen phosphate (MDP)-containing silane coupling agent and universal adhesive, used alone or in combination, on the microshear bond strength (mu SBS) to ...
