Mercerisation is a common chemical treatment for sisal fibres since it can be used to increase their interfacial adhesion to various polymeric matrices. The influence of this treatment on fibre tensile strength from the point of view of a Weibull distribution is reported. A hundred non-treated sisal fibres were individually tested and the accordance of their tensile strength to a Weibull distri...

Objectives: To evaluate the micro-tensile repair bond strength between aged and new composite, using silane and adhesives that were cured or left uncured when new composite was placed. Methods: Eighty Filtek Supreme XLT composite blocks and four control blocks were stored in water for two weeks and thermo-cycled. Sandpaper ground, etched and rinsed specimens were divided into two experimental g...

We examined macroscopically and microscopically 55 cadaver rotator-cuff tendons attached to their humeral heads to determine the distance between the edge of the articular cartilage and the tendon insertion of the supraspinatus (the width of the sulcus) and the score of regressive changes at the sulcus. In 33 specimens we measured the tensile strength. The width of the sulcus was correlated wit...

No reports have described experiments designed to determine the strength characteristics of spinal nerve roots and rami radiculares for the purpose of explaining the complexity of symptoms of medullary cone lesions and cauda equina syndrome. In this study, to explain the pathogenesis of cauda equina syndrome, monoaxial tensile tests were performed to determine the strength characteristics of sp...

The inherent strength of individual carbon nanotubes (CNTs) offers considerable opportunity for the development of advanced, lightweight composite structures. Recent work in the fabrication and application of CNT forms such as yarns and sheets has addressed early nanocomposite limitations with respect to nanotube dispersion and loading and has pushed the technology toward structural composite a...

Concrete is a brittle material whose tensile strength about one-tenth of its compressive strength. Tensile key parameter for concrete under impact loading. When turning point occurs before peak load in the load–time curve from dynamic Brazilian disc test, there no basis choosing or to calculate The objective this study determining crack initiation stress at peak. method contrasts time duration ...

Through-bolt with dowel-nut connectors are commonly used in furniture where high strength mechanical connections are required. During early periods of use, dowel-nuts were often called barrel nuts (Eckelman 1977), but the term “dowel-nut” is more descriptive, and the author has referred to them as such in the above and all subsequent publications (Eckelman 1989, 1999; Eckelman and Erdil 2000). ...

This study evaluated the tensile and flexural strength of tungsten inert gas (TIG) welds in specimens made of commercially pure titanium (CP Ti) compared with laser welds. Sixty cylindrical specimens (2 mm diameter x 55 mm thick) were randomly assigned to 3 groups for each test (n=10): no welding (control), TIG welding (10 V, 36 A, 8 s) and Nd:YAG laser welding (380 V, 8 ms). The specimens were...
