Generating Fiber Length Distribution from the Fibrogram

Textile Research Journal, 1996
Theoretical fibrograms were generated from fiber length distributions, and new fiber length distributions were then generated from these theoretical fibrograms for two, three, four, five, and six significant digits using differential and algorithm methods.

Effects of initial fiber length and fiber length distribution on the properties of carbon-fiber-reinforced-polypropylene composites

Journal of Reinforced Plastics and Composites, 2012
In this study, short carbon fiber-reinforced polypropylene composites with three different initial carbon fiber lengths were prepared by using extrusion compounding and injection molding techniques. The physical and morphological properties of the prepared short carbon fiber-reinforced composites were investigated by means of tensile test ...

Strength of short fiber reinforced polymers: Effect of fiber length distribution

Polymer Composites, 2008
AbstractIn this study, the prediction of mechanical strength of short fiber reinforced plastics (SFRPs) is made possible by obtaining a Fiber Length Distribution (FLD) efficiency factor, ηFLD, from the formerly known twofold discrete strengthening equation of Kelly–Tyson.

Rheology of natural fibers thermoplastic compounds: Flow length and fiber distribution

Journal of Applied Polymer Science, 2013
ABSTRACTThe presented study investigates the flow length and the corresponding fiber content distribution in the injection‐moulded natural fiber reinforced thermoplastics and its relation to fiber type and processing parameters such as injection pressure, temperature, injection rate and mould tempering by increasing die temperature.

Novel modified distribution functions of fiber length in fiber reinforced thermoplastics

Composites Science and Technology, 2019
Abstract Amongst the present prediction models of mechanical properties, the Weibull distribution has been introduced to describe the fiber length distribution. However, the Weibull distribution cannot capture the long tail decay, leading to underestimation of the fiber length factor (χ2). For the first time, two novel modified distribution functions

Fiber length distribution effects on the fracture of short‐fiber composites

Polymer Composites, 1990
AbstractThe effect of fiber geometry on the fracture behavior of short glass fiber‐reinforced nylons was examined. In particular a comparison was made between conventional short‐fiber composites (with feedstock made by an extrusion process) and the newer pultruded feedstock materials which have longer fiber length distributions but larger fiber ...

Are fiber strength measurements affected by cotton fiber length distribution?

2002
Two experiments were performed to investigate the effect of variations in fiber length distribution on strength measured by different instruments. In these experiments, we assumed that cutting the fibers along their length would not have any effect on the strength measurements.

Distribution function of fiber length in thermoplastic composites

Composites Science and Technology, 2016
Abstract Due to the strong correlation with material properties, fiber length distribution in polymer composites has been extensively investigated. The distribution exhibits steep increase until a peak followed by a long tail decay, which has been analyzed in terms of Weibull distribution.

Fiber length distribution and sheet properties

2010
Although fiber length is one of the most often measured property of paper raw materials, the pure effect of it on paper properties is not usually clear. The reason for that is the difficulty to vary only the fiber length while other properties such as fiber width are kept unchanged.
