Abstract Scope |
The evolution of materials used as armor is related to development of firearms. Given the environmental problems with synthetics and the long period of time that flax is adopted in numerous applications, the present work will characterize the flax fabrics impregnated with STF of SiO2 for engineering and ballistics application, with compositions of 50, 60, 70 wt.% of silica. Through FTIR analysis, the functional groups of NLFs was observed. Through XRD, the crystallinity index of the fiber was estimated in 57.0%. The silica pointed to a hexagonal structure. TGA tests indicated that the thermal stability of the fabric was compromised although there was a smaller mass loss for the composites. The viscosity analysis pointed that PEG 400 had its viscosity increased by 11 times with the addition of 50 % of SiO2. The yarn pullout test pointed a considerable increase in friction for fabrics with 50 and 60% of STF. |
