Even today, a detailed description of the damage progress in wood or wood materials under tensile loading is still a challenge. The complexity of the damage behaviour results from the various mechanisms occurring simultaneously at several length scales. So far, few studies focused on mechanical behaviour of wood or wood materials by analysing acoustic emission (AE), although AE can provide info...

Natural composites are one of the smart materials that have opportunity to replace use synthetic composites. and metal materials. Layered structural provide nearly uniform properties on all sides. The purpose this study was determine mechanical tensile, compressive impact behavior bamboo fiber polymer with a layered structure. This research method is experimental where specimens made in 2 quasi...

Tensile properties of bamboo laminae, prepared from bamboo slivers, selected from different regions of bamboo culms (Dendrocalamus strictus), increases from inner to outer region for any cross section and the same is experienced from bottom to top. Application of rule of mixture, on linear regression line drawn from test results, show that fiber strength increases and matrix strength decreases ...

The optical anisotropy of layered perovskites is exploited in flexible free-standing polymer films through multiple stretch/release cycles at low tensile stress, to enhance the emission intensity resulting composites.

[ABSTRACT] Chemical compositions and fiber measurement of virgin and recycled fibers from three sources were determined. Results revealed that virgin southern pine fiber had highest slcohol-benzene extractive and lignin contents and lowest holoand alpha-cellulose content among the three fiber types. Fiber length distribution of virgin fiber was less sensitive to disintegration. Effects of recyc...

The purpose of this study was to evaluate the effect of the covering enamel layer of various thicknesses on the color of layered resin composites (LRC). To this end, the CIELAB parameters of the following were evaluated: underlying base (ULB: 2.0 mm of body shade + 3.0 mm of opaque shade), inherent color of the enamel shade (4.0 mm of enamel shade + ULB), and LRC disks (0.5, 1.0, 2.0, 3.0 mm of...
