✦ Synopsis

The optimal curing parameters of a cure cycle for achieving maximum mechanical properties of Gr/ep composite laminates are determined via a multi-level optimization approach. Laminated composite specimens cured under various pressures, temperatures and times are tested with an Instron testing machine. Test results are then used in the proposed multi-level optimization method to determine the optimal curing parameters. The effects of the curing parameters on the mechanical properties of the laminates are studied and discussed. It was found that a cure cycle with two pressure-temperature-time steps can yield composite laminates with comparatively good material properties.

A numerical model has been developed to analyze the die and post-die temperature and degree of cure profiles in pultruded composites. The model utilizes a fixed control volume based finite difference approach (S. V. Patankar, Numerical Heat Transfer and Fluid Flow. McGraw-Hill, NY, 1980). The method

Orthogonal cutting mechanisms in the edge trimming of Graphite/Epoxy laminate with polycrystaUine diamond tools were studied. Chip formation, cutting force, and surface morphology were evaluated with respect to tool geometry, process conditions, and ply distribution in the laminate. As with the trim
