A Study on the Processing of High Functional Composites and the Evaluation of Its Characteristics

Filament winding method is widely used for composite fabrications using low viscosity liquid formation and processing asymmetrical structures of pressure vessel, pipe, rocket motor case etc. The filament winding method is affected by several parameters such as pot life of process time, viscosity of resin, filament winding temperature and schedules, curing condition, post curing condition of resin. The degree of robin impregnation and void contents was measured by tension. To develope high functional composite materials the rotation(5, 10, 15, 20, 30rpm) was controlled by D.C motor. And the wiper to give proper tension was equipped between strand and robin bath. The resin is hooked by the design wiper and the viscosity of resin was measured by viscometer. The adequate cure schedule was found by DSC. NOL ring test is carried to investigate the basic physical properties such as stress analysis, design technology of structure of winding.
