Poor bonding with its accompanying matrix remains the major factor that inhibits the widespread use of natural fiber as filler for composite materials. Recent literature has suggested that this matter can be addressed by applying fillers in nanometer size. Thus, the present study is carried out to investigate the effects of incorporating rattan powder of nanoparticle size into polypropylene ...

Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance.

The polypropylene fibers claimed contribution to the concrete performance subjected to crack opening and slippage [8]. Furthermore, the fibers reinforced the ... 作者：RAS Mohamed · ‎被引用次数：18 · ‎相关文章

Abstract. This paper presents the effects of low volume fraction of polyvinyl alcohol (PVA) fibers on the mechanical properties of oil palm shell (OPS) high strength lightweight concrete mixtures. The slump, density, compressive strength, splitting tensile strength, flexural strength, and modulus of elasticity under various curing conditions have been measured and evaluated.

fibers were characterized as follows: short (≤1 mm), medium (1-2 mm), and long (≥2 mm) (Table 1). Distribution was performed using mesh sizes of 14 and The effects of fiber length and fiber loading on the mechanical properties of wood-plastic (polypropylene) composites 192 Table 1.

The tensile properties of polypropylene fibers, produced in a short‐spin line, are correlated with the parameters of the three processing stages (spinning, drawing, and annealing), and with the molecular weight distribution.

A reticular polypropylene fiber and a single polypropylene fiber were used to improve the strength of the high strength concrete, but the effects of the two fibers on the slump and strengths were quite different. The reasons of the differences were the surface area and the modulus of elasticity of the fibers.

List of known side effects. Polypropylene can give rise to the allergic reactions that people exposed to it have. Body systems affected by polypropylene. Polypropylene is bad for the endocrine system. It can cause genetic mutations and tumors. Polypropylene is bad for the reproductive system.

effort was made to study the effect of polypropylene (PP) fibers on mechanical properties and shrinkage of mortar incorporating NS. Three fiber volume fractions, 0.1%, 0.3% and 0.5% were considered. Compressive and flexural strength, water absorption and shrinkage of …

The positive effects of polypropylene fibers, which may contribute to the increase of the mechanical properties of high-strengt h concrete, are concluded as foll ows: The fibers function as micro ...

Polypropylene fiber content is within 1.3Kg/m 3 , and with the increase of fiber content, the effect of aeolian sand mortar is obvious; when the content exceeds 1.3Kg/m 3 , the shrinkage and mechanical properties are shrunk; the wind and sand accumulation mortar is aggregated.

Portland cement, crushed stone, sand and superplasticizer were used to obtain a high strength concrete with a low water to binder ratio. A reticular polypropylene fiber and a single polypropylene fiber were used to improve the strength of the high strength concrete, but the effects of the two fibers on the slump and strengths were quite different.
