“…The second stage begins around 311 °C, with a maximum loss at 356 °C extending to 451 °C. This mass loss represents about 67.38% and may be associated with depolymerization and degradation of epoxy polymeric chains [ 52 , 53 , 54 ]. Finally, a third stage, with a mass loss of 12.04% up to 700 °C, is attributed to inorganic residues of the final degradation of the resin.…”

Titica vine (Heteropsis flexuosa) is a typical plant of the Amazon region commonly used for making baskets, bags, brooms and furniture, owing to its stiff fibers. In spite of its interesting properties, there is so far no reported information regarding the use of titica vine fibers (TVFs) in engineering composite materials. In this work, the TVF and its epoxy composites were for the first time physically, thermally and mechanically characterized. Additionally, the effect of two kinds of chemical treatments, one with sodium carbonate and one with calcium lignosulfonate, as well as different volume fractions, 10, 20, 30 and 40 vol%, of TVF-reinforced composites were assessed for corresponding basic properties. The thermogravimetric results of the composites reveal enhanced thermal stability for higher TVF content. In addition, the composite incorporated with 40 vol% of TVFs treated with sodium carbonate absorbed 19% more water than the composites with untreated fibers. By contrast, the calcium lignosulfonate treatment decreased water absorption by 8%. The Charpy and Izod impact tests showed that the composites, incorporated with the highest investigated volume fraction (40 vol%) of TVF, significantly increased the absorbed energy by 18% and 28%, respectively, compared to neat epoxy. ANOVA and Tukey statistical analyses displayed no direct influence of the chemical treatments on the energy absorption of the composites for either impact tests. SEM images revealed the main fracture mechanisms responsible for the performance of TVF composites.

“…This material has high hardness and can resist the initial impact of the projectile and damage it [6]. Modern ballistic vests are made from advanced ceramics, where the most common are alumina (Al2O3), silicon carbide (SiC), and boron carbide (B4C) [7,8], in addition to being reinforced with fabric fibers and/or natural fibers [9][10][11][12]. Three factors make ballistic armor efficient: mobility, penetration resistance, and high impact absorption.…”

This article explores the ballistic and mechanical performance of HDPE matrix composites reinforced with alumina and silicon carbide particles, to be used as lightweight body armor. After processing, the composites were evaluated by tensile tests, Izod impact, and Shore D hardness. In addition, depth of penetration (DOP) and energy absorption tests were performed with chronograph simulating .22 ammunition in the ballistic test. Samples A80 and A70 had the lowest DOP result (15.98 and 17.98 mm respectively) indicating that these samples had the best ballistic performance. Mechanical tests performed on samples A00, A40, A50, and A60 showed that the deformation and tensile strength were reduced with the addition of ceramic reinforcement. Impact resistance also decreased. Shore D hardness showed a considerable increase in hardness of A40, A50, and A60 compared to A00.

Natural fiber composites are hybridized nowadays to explore the synergetic effect of more fibers used in the properties of the composites. The natural fiber hybrid composite made with filler material has excellent wear resistanc characteristics. This research work examined the mechanical properties, namely tensile, flexural, interlaminar shear strength, impact strengths, and hardness of the natural fiber reinforced hybrid composite that uses jute, snake grass, and kenaf fibers as reinforcement with various fiber volumes. Further, the wear behavior of the hybird composites was enhanced by using Annona reticulata (custard apple) seed powder as a filler material. This study revealed that the sample has an equal proportion (12.5% of each) of snake grass and kenaf fiber (without filler) has excellent mechanical strengths. The wear behavior of the sample with 5 wt. % filler shows lower wear rate than other samples.
