Genetic Algorithm Optimization of a Filament Winding Process
"... Abstract. This paper describes a research effort to improve the efficiency of a filament winding process by combining the simulation capabilities of the WITNESS modeling program with the search capabilities of a genetic algorithm. Results show that the genetic algorithm is able to reduce the cost of ..."
Single Mandrel and
"... Coils are wound on mandrels that are retained as the primary structural elements of the TS. Mandrel spool pieces are bolted together at their flanges. A large number of bolts are used to obtain good bending resistance. The system of three vertical support rods, and three lateral support points make- ..."

CONSOLIDATION OF FILAMENT WOUND LAMINATES: MODELLING APPROACHES
"... The filament winding process is a manufacturing technique in which a resin-impregnated continuous filament (or tape) tow is wound over a rotating mandrel. The synchronized movement of both the mandrel and the delivery head accomplishes the precise positioning of the fibres on the mandrel surface, le ..."

Rho GTPases control polarity, protrusion, and adhesion during cell movement
- J. Cell
, 1999
"... Abstract. Cell movement is essential during embryogenesis to establish tissue patterns and to drive morphogenetic pathways and in the adult for tissue repair and to direct cells to sites of infection. Animal cells move by crawling and the driving force is derived primarily from the coordinated assem ..."

assembly and disassembly of actin filaments. The small GTPases, Rho, Rac, and Cdc42, regulate the organization of actin filaments and we have analyzed their contributions to the movement of primary embryo fibroblasts in an in vitro wound healing assay. Rac is essential for the protrusion of lamellipodia
Structural Analysis and Strain Monitoring of the Filament Wound Motor Case
- Journal of Composite Materials
, 2002
"... ABSTRACT Filament wound structures such as pressure tanks, pipes and motor cases of rockets are widely used in aerospace applications. The determination of a proper winding angle and thickness is very important to decrease manufacturing difficulties and to increase structural efficiency. In this st ..."

. In this study, possible winding angles considering the slippage between a fiber and a mandrel surface are calculated using the semi-geodesic path equation. In addition, finite element analyses using ABAQUS are performed to predict the behavior of filament wound structures considering continuous change
EXPANDABLE AND COLLAPSIBLE WINDING MANDREL: A LITERATURE REVIEW
"... ABSTRACT An accurately wound coil is the key component to eliminate transformer failures in the field. Therefore choosing correct mandrel is the first important step in coil winding process. The mandrel design is dependent on shape of the composite part to be produced and removal of the mandrel aft ..."

Burst Tests of Filament-wound Graphite-epoxy Tubes
"... ABSTRACT: A test program was conducted to investigate the failure modes of undamaged and damaged graphite-epoxy cylindrical tubes subjected to internal pressure. Some tubes were intentionally damaged by either a longitudinal-line cut or a single-point impact. Both types of damage were intended to si ..."

-damaged tubes, the results show that the burst pressure decreases with increasing impact load. At an impact load of 1493N (335 lb), the burst pressure decreases by 33 % compared to the undamaged condition. KEY WORDS: graphite epoxy tubes, filament wound composites, internal pressurization, impact damage
