Abstract

It was shown that the fume generation was the problem in the plasma jet cutting of FRP in previous report. In this report, the effects of cutting conditions and the glass contents in FRP on the fume generation was studied. The fume was collected with the high volume air sampler prescribed in JIS-Z-3930. Some of the counterplans were considered for decreasing the hume.
The main results obtained are as follows.
1) The fume increased in proportion to the glass content in FRP.
2) The catched fume corresponded to about 1/3 of glass content in FRP.
3) The fume generation decreased 30-50% in wet cutting condition compared with dry one.
4) The perfect catch of the fume was difficult by means of setting water under the material to be cut.
5) Almost all the fume was composed with the particles less than 0.1 micron.
6) The composition of the fume was nearly same as the glass composition and it was composed with amorphous materials.
