The effect of nanoclay content on the properties of glass fibre reinforced, waterborne epoxy laminates is investigated. Fourteen ply nanocomposite laminates containing 0, 0?1, 0?2, 0?5, 1 and 2 wt-% cloisite Na nanoclay are fabricated by a hot press. The interlaminar shear strength, flexural strength and flexural stiffness of the fabricated nanocomposites are characterised. In addition, the the...

A laminated composite was produced using a thermoplastic prepreg by inserting an interleaved film with the same type of matrix as the prepreg during the lay-up process to improve the low interlaminar properties, which is a known weakness of laminated composites. Carbon fiber fabric (CFF) and polypropylene (PP) were used to manufacture the thermoplastic prepregs. Eight prepregs were used to prod...

The use of biomass combustion ash as a reinforcing filler has taken the attention in recent years to reduce overall production cost and increase mechanical properties plastics. This study evaluates effect boilers (BBA) on polyamide 6 composites (PA6). chemical composition thermal stability BBA were analyzed by X-ray fluorescence (XRF), Thermogravimetric analysis (TGA), Differential (DTA) thermo...

In this paper, twelve concrete beams with two different layers of were evaluated as a simply supported beam under four-points loading. The assembled types layers, one which was normal-weight (NWC) and the other lightweight aggregate (LWAC). investigated parameters thickness to overall depth (hLW/h), compressive strength normal concrete. Due weak aggregates used, exhibits more brittleness lower ...

Microtubules are rigid polymers that contribute to the static mechanical properties of cells. Because microtubules are dynamic structures whose polymerization is regulated during changes in cell shape, we have asked whether the mechanical properties of microtubules might also be modulated. We measured the flexural rigidity, or bending stiffness, of individual microtubules under a number of diff...

This study compared nanofilled and microhybrid composites polymerized by different light polymerization modes, and the effects these modes had on the mechanical properties of the composites. The following mechanical properties were measured: Vickers microhardness numbers, diametral tensile strength, flexural strength, and flexural modulus. The filler content (Wt%) present in the resins was inve...

The use of agriculture residues as filler in composites is increasing due to their strength, abundance and low cost. Soya stalks show promising renewable natural fiber. In polyethylene composites the physical and mechanical properties (flexural resistance, tensile, impacted absorbed energy, water uptake and thickness swelling) was examined at different composites. The results showed that, the m...

The mechanical properties of newly developed aspen fiber–polypropylene composites (APC) were experimentally explored and numerically predicted at the temperatures and humidity that are typical for domestic housing applications. The mechanical properties of APCs with five different fiber-loadings were evaluated at the room temperature, 4 �C, and 40 �C. Environmental effects on the mechanical pro...

With the aim of extending the use of integrated variational principles on fluid and deckplate to the large deflection analysis of floating roofs, this paper investigates the significance of theflexural and membrane components in the formulations of the deck plate. Applying integratedvariational principles on deck plate and fluid facilitate the treatment of the compatibility ofdeformation betwee...

Polymer blends composites were prepared according to the formula [84%LLDPE:15%((100-X)%PP:X%PVP):1%B.P] with weight ratios selected for X values (0,4,8,12,16 %), as strips by double screw extruder and use press process the strips to prepare the samples according ASTM specification, the mechanical properties were studied for all theprepared samples which are (tensile, flexural, compression, impa...
