Self-reinforced polypropylene composites based on low-cost commercial woven and non-woven fabrics
(John Wiley & Sons Ltd, 2018-01-28)
In the present paper, different self‐reinforced polypropylene (PP) composites based on low‐cost commercial woven (w) and non‐woven (nw) fabrics were obtained. Hot compaction (HC) and film stacking (FS) followed by compression ...
Self-reinforced composites obtained by the partial oxypropylation of cellulose fibers. 2. Effect of catalyst on the mechanical and dynamic mechanical properties
(SPRINGER, 2009)
This work describes the partial oxypropylation of filter paper cellulose fibers, employing two different basic catalyst, viz., potassium hydroxide and 1,4-diazabicyclo [2.2.2] octane, to activate the hydroxyl groups of the ...
Self-reinforced composites obtained by the partial oxypropylation of cellulose fibers. 1. Characterization of the materials obtained with different types of fibers
(ELSEVIER SCI LTD, 2009)
The in-depth oxypropylation of different types of cellulose fibers, namely Avicel, Rayon, Kraft, and Filter Paper, was investigated. New biphasic mono-component materials were obtained, which could be hot-pressed to form ...
Effect of consolidation degree on the fracture failure behavior of self-reinforced polypropylene composites as assessed by acoustic emission
(John Wiley & Sons Inc, 2010-06-25)
In this work, the fracture and failure behavior of self-reinforced polypropylene composites (SRPPC) was studied. As reinforcement woven fabric, whereas as matrix materials α and β crystal forms of isotactic polypropylene ...
Mechanical behaviour of self-compacting concrete with hybrid fibre reinforcement
(Springer, 2007-03-01)
In this study, fibre-reinforced self-compacting concretes were developed for precast building components, incorporating either adherent metal fibres or polymeric synthetic slipping fibres or a combination of both. To achieve ...
Fracture behavior of recyclable all-polypropylene composites composed of α- and β-modifications
(Sage Publications Ltd, 2011-11)
The fracture behavior of all-PP composites was studied under quasi-static loading conditions. Fracture toughness was evaluated by means of different fracture mechanics approaches depending on materials’ behavior. Composites ...
Influence of alveolar bone level on the pull-out bond strength of fiber-reinforced composite posts to root dentin
(2016-03-01)
This in vitro study evaluated the influence of alveolar bone level and type of cement on pull-out bond strength between different fiberreinforced composite (FRC) posts and root dentin. Sixty bovine teeth were sectioned, ...
Acoustic Emission behavior of thermally damaged Self-Compacting High Strength Fiber Reinforced Concrete
(Elsevier, 2018-10)
This paper investigates the effect of high temperature on two different Self-Compacting (SC) cementitious composites. SC-High Strength (SCHSC) and Fiber-Reinforced Concrete (SCHSFRC) samples were tested in three-point ...
Effect of Chlorhexidine and Ethanol on the Durability of the Adhesion of the Fiber Post Relined with Resin Composite to the Root Canal
