Abstract Scope |
Epoxy matrix composites reinforced with fique fabric were developed using the layer intercalation technique (hand lay-up) with the objective of investigating its potential use as a ballistic material. The absorption of energy and the effects of natural aging on the fique fabric and its composites were analyzed. Samples were exposed to abiotic degradation test at three different times, being 30, 60 and 90 days, in order to assess the effects of climatic conditions on the morphology and dynamic properties of the material. The effects of natural aging on the morphology of materials were characterized by the weakening of the polymer matrix, the appearance of cracks and internal fractures. As a result, the ballistic behavior of the composites was directly affected, reduced from 232 to 177 J, as a result of various types of abiotic degradation suffered by the samples, exposure to UV radiation, rainwater/humidity and temperature changes, stands out. |
