Evaluation of marginal microleakage in Class II cavities: Effect of microhylolrid, flowable, and compactable resins
(Quintessence Publ Co IncCarol StreamEUA, 2003)
Preparation and characterization of bentonite nanocomposites via sol–gel process
(Springer, 2019-07-22)
Different nanocomposites silica-resin based were prepared and characterized in order to achieve a porous monolith that contains bentonite and allows the flow of aqueous systems. The bentonite used to prepare the nanocomposites ...
Effective properties evaluation for smart composite materials
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2012)
The purpose of this article is to present a method which consists in the development of unit cell numerical models for smart composite materials with piezoelectric fibers made of PZT embedded in a non-piezoelectric matrix ...
A new damage model for composite laminates
(ELSEVIER SCI LTDOXFORD, 2013-08-02)
Aircraft composite structures must have high stiffness and strength with low weight, which can guarantee the increase of the pay-load for airplanes without losing airworthiness. However, the mechanical behavior of composite ...
Mechanical and microstructural characterization of epoxy/sawdust (Pinus elliottii) composites
(2020-01-01)
The use of wood residues in polymeric matrices is notable for promoting significant mechanical reinforcement of the matrix. Such composites are widely used in the development of new composite materials with tunable mechanical ...
Lead zirconate titanate/polyurethane (PZT/PU) composite for acoustic emission sensors
(2001-01-01)
Piezoelectric composite, made from ferroelectric ceramic lead zirconate titanate (PZT) and vegetable based polyurethane (PU) polymer, was doped with a semiconductor filler, graphite. The resulting composite (PZT/C/PU) with ...
