The Creep Properties of Paper

TAPPI Journal, 2022
The creep properties of alpha-pup handsheets were determined at various constant tensile loads and relative humidities for the purpose of clarifying the prerupture mechanical behavior of paper.

Optical Properties of Paper

Trans. of the IInd Fund. Res. Symp. Oxford, 1961, 1961
Optical properties of paper are those that govern its visual appearance-mainly, colour, opacity and gloss. These depend on the fact that paper consists of a network of doubly refractive transparent fibres immersed in air as medium and, in some cases, the optical properties can be expressed in terms of the absorption and scattering coefficients of the ...

The dielectric properties of paper

Journal of the Institution of Electrical Engineers, 1935
This paper is an outline of a detailed investigation of the fundamental dielectric propeities of paper. Measurements were made under carefully controlled conditions covering a very wide range, on three representative kinds of paper, both in the dry condition, and after impregnation with oil.

Electrostatic properties of xerographic papers

Journal of Electrostatics, 1978
Abstract Static electrification properties of papers used in xerographic photocopying have been studied. It is shown that the resistance of the papers decrease exponentially with increasing relative humidity of the surrounding air: an increase of 6% in the relative humidity resulting in a halving of the resistance. The relaxation times for charges on

Fracture Properties in Filled Papers

Trans. of the XIIth Fund. Res. Symp. Oxford, 2001, 2001
The mechanical properties of paper are impaired by the addition of filler. The beating of kraft pulp and addition of starch are possible remedies for this. However, beating also has negative effects because it reduces opacity and bulk, and starch effects are limited by retention. Optimal use of the kraft pulp and starch is therefore important.

The Interdependence of Paper Properties

Trans. of the IInd Fund. Res. Symp. Oxford, 1961, 1961
The difficulties involved in interrelating paper properties are examined. Qualitative relationships through trends and experience are noted and the special case of quantitative interrelationship among burst, tensile and stretch is described. More basic considerations such as fibre length, fibre strength, sheet density, fibre orientation and interfibre

Mechanical properties of filled paper

1988
The tensile stress-strain properties and the dynamic mechanical properties at room temperature have been measured for paper sheets containing up to 60% by weight of clay. Addition of the clay filler drastically reduces the stiffness, strength and ductility of paper.

Geometrical Properties of Paper Spring

2008
Recent advances in the research of mathematics and science in origami is rapidly transforming the ancient art of paper folding into a challenging field of study. This paper describes a deployable spring series which is an extension of the original paper spring created by Jeff Beynon. The model was studied and researched through calculations, models and

Presidential Papers: A Property Issue

The Library Quarterly, 1982
The dramatic change which occurred in the ownership of presidential papers due to litigation surrounding former President Nixon's papers is the underlying theme in this discussion of the property aspects of presidential papers from George Washington to the present. The paper begins with the background and a brief summary of the Supreme Court case Nixon
