Content Ratio

When fiber-reinforced composites (FRC) are subjected to compressive load parallel to the fiber direction, they fail as a result of fiber buckling and/or transverse failure of the resin. Compressive loading brings about two buckling modes to fibers. The first mode is shear buckling, and the other is transverse buckling. Recent studies support the hypothesis that fiber buckling causes compressive rupture. In this study, finite element modeling software was employed to examine the behavior of a resin-embedded single fiber in terms of fiber content ratio. The performed modeling procedures illustrated that the single fiber experiences three discrete failure modes depending on fiber content ratio; and then a corrected equation was proposed for each mode. Fiber content ratio of the composite is one of effective parameters to determine the compressive strength value. Optimum fiber content ratio has been measured using finite element method. Numerical results are compared to experimental ones to analyze the obtained results. The optimum fiber content ratio calculated by the finite element modeling was measured 40% in this paper.

Abstract Tire vibration modes are known to play a key role in vehicle ride, for applications ranging from passenger cars to earthmover equipment. Inputs to the tire such as discrete impacts (harshness), rough road surfaces, tire nonuniformities, and tread patterns can potentially excite tire vibration modes. Many parameters affect the frequency of tire vibration modes: tire size, tire construction, inflation pressure, and operating conditions such as speed, load, and temperature. This paper discusses the influence of these parameters on tire vibration modes and describes how these tire modes influence vehicle ride quality. Results from both finite element modeling and modal testing are discussed.

Abstract Development of the banded radial tire is discussed. A major contribution of this tire design is a reliable run-flat capability over distances exceeding 160 km (100 mi). Experimental tire designs and materials are considered; a brief theoretical discussion of the mechanics of operation is given based on initial two-dimensional studies and later on more complete finite element modeling. Results of laboratory tests for cornering, rolling resistance, and braking are presented. Low rolling resistance, good cornering and braking properties, and low tread wear rate along with good puncture resistance are among the advantages of the banded radial tire designs.
