Abstract

Compound combinations have been used to test dimensional stability in thermochemistry. Nylon 6/6´s dimensional stability as a matrix around bamboo fiber was tested. The purpose of the study was to identify a possible relationship between nylon 6/6 and bamboo fiber when combusted against flame spread and melt-dripping to determine whether it could be a viable material to use in substitution of more environmentally damaging and economically draining materials. It was hypothesized that there would be a converse relationship between the amount of nylon 6/6 added and the flame-retardancy of the sample justified by the reduction in melt dripping and flame spread. The UL-94 vertical burning tests were conducted to determine flame spread and melt dripping after two separate ignitions. Results showed that nylon 6/6 began to break away when set on fire as its dimensional stability was not strong in its current state as a matrix. Further application of nylon 6/6 seemed to decrease variance in general and increase flame spread. In conclusion, the results showed that nylon 6/6 had an increasing impact on flame spread and ignition length and a negative impact on flame retardancy when surrounding bamboo fiber. ANOVA testing was used to find a p-value of less than 0.001 rejecting, the null hypothesis that the means in the groups were similar. It was found using post hoc testing that the initial ignition until extinguishment times of the layered groups differed significantly from that of the control group.
