Compósitos de matriz poliéster reforçados por fibras curtas de sisal Tensile properties of unsaturated Polyester composites reinforced by short sisal fibers

Polímeros, 1999
As propriedades tênseis de compósitos de matriz poliéster, reforçados por fibras curtas de sisal foram determinadas em função do comprimento, teor e orientação das fibras. Os resultados mostram que, para os compósitos investigados, a resistência à tração

Short-Beam Shear Fatigue Behavior on Unidirectional GLARE: Mean Shear Stress Effect, Scatter, and Anisotropy

Fibers
This paper investigates the effect of mean shear stress on short-beam shear fatigue in a GLARE 1-3/2 commercial fiber–metal laminate (FML). This study explores three shear stress ratios (Rτ 0.1, 0.3, and 0.5) and two material orientations (longitudinal ...

Solid-state reaction in nanoparticulate alumina/LZSA glass-ceramic composites

Cerâmica
In this work, some properties, such as sinterability, modulus of elasticity (E), coefficient of thermal expansion (CTE) and dielectric constant (εr), of composites constituted by nanoparticulate alumina (27-43 nm, 35 m2.g-1) in different contents (0 to ...
