Microwave assisted pultrusion of an epoxy composite
- UMIST, Manchester (United Kingdom)
A 6mm diameter cylindrical profile based on E-glass fibers and a BF{sub 3}-triamine-epoxy resin system has been manufactured by Microwave Assisted Pultrusion (MAP) using a single mode resonant microwave cavity operating in a TM{sub 010} mode at 2450 MHz. Power transfer is at least 70% and pulling speeds of more than 2m/minute have been achieved for a power input of about 800W. The results are consistent with earlier MAP studies using unsaturated polyesters, epoxies urethane acrylates and vinyl esters. The results provide a sound basis for proposing the use of this type of epoxy system as a material that is suitable for a high speed gel-cure pultrusion process that uses both a microwave heating cavity and a conventional pultrusion die.
