Filament winding is a manufacturing method for making tubular and cylindrical shapes of extreme strength and light weight. The technology involves wrapping a mandrel — which is a reusable steel core with resin-impregnated carbon fiber, Kevlar, or Fiberglas fiber — and then curing it in an oven.

Material Properties Filament Wound Composite Structures Textbook Definition: A composite material is a macroscopic combination of two or more distinct materials, having a recognizable interface between them. Practical Definition: A versatile solution to today's design problems. Amalga Composites offers a variety of light weight and high. metal tubes or commercial composite tubes which were consisted of an axial ﬁber core with a woven cloth over-wrap and vinylester resin. In that work, we found  that the axial strain is a much smaller fraction (1/10) of the hoop strain than for the aluminum tubes. In the present study, we used ﬁlament wound specimen tubes.

The main objective of this work is to determine the in-plane mechanical properties of unidirectional laminae made of kevlar49/epoxy (KRP) and carbon/epoxy (CFRP) materials from tube expansion tests.
Testing the tubes at high strain rates resulted in substantial increases in burst strength and ultimate hoop strain as compared with the quasi-static and low strain rate values.

Phone: Fax: [email protected] A numerical/experimental study was conducted to investigate the failure pressure of filament wound composite tubes subjected to internal pressure. A progressive failure analysis was performed using ABAQUS (version ) commercial software employing an alternative damage model implemented by the user subroutine (UMAT).
The quality and material properties of filament-wound tubes depend on a variety of parameters. Numerous ways of classifying these parameters have been established. Cohen () for example categorized influential parameters into five groups, which are.
Filament wound composite structures are widely used in the field of pressure vessels, tubes, pipelines or rocket cases.
The mechanical behavior of these structures is typically different from. analysis processes of filament wound composite tubes under pure and combined loading. The problem is studied by using a computational tool based on the Finite Element Method (FEM).
Filament wound tubes are modeled as single layered orthotropic tubes. Several analyses are performed on layered orthotropic tubes by using FEM.

SUMMARY: Residual stresses throughout the cure cycle in thick filament wound tubes. Experimental investigations were performed on strain characteristic of filament wound composite cylinder. Cylinders are wound with S-1 glass fiber and epoxy resin, and then subjected to an axial tension.
During loading, strains at three fiber crossing position and one laminate region on cylinder’s surface are measured by gauges for better understanding strain field.
In order to investigate these parameters, internal pressure tests are done on the filament-wound composite tubes having internal diameter ± mm and length ± mm according to ASTM D standard. The tubes for the testing are manufactured by wet filament winding methods of [± 60°] E-glass/Epoxy of various wall thicknesses.In this case the strain rate was held constant and the temperature was varied.
As expected, as the temperature increases the strength and modulus of the material decline, mimicking the effects of changing strain rate. The equivalence of strain rate and temperature can be demonstrated by performing this simple exercise.Burst Strength of FW-FRP Composite Ring The results of ring burst tests are tabulated in Table 2.
