“…Como matriz polimérica se ha empleado la resina viniléster (EPOVIA RF-1001) por presentar buenas propiedades mecánicas y de trabajabilidad. En la Tabla I se muestran las propiedades mecánicas (módulo de elasticidad y límite elástico) de los materiales empleados, correspondientes a valores sumistrados por el fabricante y que fueron validadas en trabajos previos (5). Debido a que la misión de la cerámica es erosionar el proyectil y distribuir la carga en un área más amplia del panel posterior, el porcentaje de partículas debe ser lo más elevado posible aunque proporcionado con una cantidad de matriz que garantize la cohesión.…”

En este trabajo se presenta el proceso de fabricación de un material compuesto de matriz polimérica y carga cerámica, su caracterización mecánica estática y su comportamiento frente a impacto. Como matriz se ha empleado una resina viniléster y como carga cerámica se han empleado partículas de alúmina y carburo de silicio. Estas partículas, con un tamaño medio comprendido entre 1.5 mm y 4.5 mm, presentan bajo coste y alta disponibilidad. La compactación uniaxial permitió obtener losetas con un elevado porcentaje de partículas cerámicas (hasta el 80% en peso) y baja porosidad. Se han realizado ensayos de compresión estática sobre el material desarrollado para analizar la influencia de varios factores: fracción volumétrica de partículas, tamaño de partícula, material de las partículas y temperatura. La resistencia a compresión cuasiestática del nuevo material compuesto se incrementa al aumentar la fracción volumétrica de partículas, siendo prácticamente independiente del tamaño de éstas, en el rango granulométrico considerado. El incremento de la temperatura supone una disminución en las propiedades cuasiestáticas. El bajo coste del material desarrollado justifica su aplicación en protecciones que requieran de una eficiencia frente a impacto intermedia entre la correspondiente a placas metálicas y a los paneles cerámica/metal. Palabras clave: Partículas cerámicas, Matriz polimérica, Eficiencia balística, Compresión estática, Ensayo de profundidad de penetración. Manufacturing and compressive behavior of a polymeric material loaded with ceramic particlesA polymeric material loaded with ceramic particles was developed and its static and impact behaviors were determined. A vinylester resin, used as matrix, was reinforced with alumina or silicon carbide particles. These particles, with mean sizes between 1.5 and 4.5 mm, are cheap and readily obtainable. The manufacturing process produced tiles with a high percentage of ceramic particles (up to 80% by weight) and low porosity. The static compressive behavior of the composite was examined to consider various factors: ceramic fraction, particle size, material of particles and temperature. A higher volumetric fraction of particles produces an increase of stiffness and raises the yield stress of the composite; the influence of size of particles is not determinant. High temperatures produces a decrease of the mechanical properties. The efficiency of this low-cost material is halfway between that of the conventional metallic materials and the monolithic ceramic tiles used in lightweight protection. Keywords: Ceramic particles, Polymeric matrix, Ballistic efficiency, Static compression, Depth of penetration test. INTRODUCCIÓNEn el proceso de diseño de protecciones frente a impacto, los requerimientos más importantes son elevada capacidad de detención de la amenaza, baja densidad y reducido coste de los materiales. Se pueden emplear diferentes materiales para satisfacer estos requerimientos. Los materiales metálicos pueden, en general, responder a los requerimientos de protecci...

In this study, the newly designed Al-9Si/SiC particles (SiC p ) + Ti-fiber (2step-reinforced Al-9Si alloy matrix) metal matrix composites (MMCs) were fabricated by hot-pressing sintering at 560°C. 2step-reinforced Al-based MMCs were characterized by thermal shrinkage, phase transition, microstructure and tensile strength. The addition of Ti-fiber reduced thermal shrinkage was caused by temperature difference in sintering process as well as enhanced assistance for tensile strength and plastic deformation at room temperature. Experimental results reveal that the 2step-reinforcment sintering by ceramic and metal has a significant effect to increase interface bonding in boundary of each component material and the improved mechanical properties were due to the influence of interfacial product by diffusion. Tensile strength and elongation at room temperature by 2step-reinforcement were improved in 19.5% and 26.2% more than those of Al-9Si/ SiC p , respectively. Especially, it reveals that diffusion direction may be varied by sintering methods at low temperature in this study.

“…The use of ceramic/metal bi-layer armor structures provides lighter designs compared to monolithic metal armors showing the same or better ballistic protection. Several researchers have investigated the ballistic impact response of different ceramic/metal armor structures using experimental, numerical and analytical methods or combinations of these methods [Zaera and Sánchez-Gálvez (1998), Zaera et al (2000), Lee and Yoo (2001), Arias et al (2003), Gonçalves et al (2004), Mahdu et al (2005), Chi et al (2013), Serjouei et al (2015), Tang and Wen (2017)]. …”

The study presents a comparative numerical investigation on ballistic performance of ceramic/metal armor structures. 2D axisymmetric numerical model was developed for ballistic impact simulations using LS-DYNA ® finite element software. The armor structures included combinations of boron carbide (B4C), Al6061-T6 and 4340 steel constituents. The interfaces in the armor structure were modelled with an epoxy resin adhesive. In order to define proper material behavior, Johnson-Holmquist-Ceramics material model for B4C and Plastic-Kinematic material model for Al6061-T6, 4340 steel and epoxy resin was used. The armor structures were subjected to 7.62 mm ogive-nosed steel projectile impact. In the first section, the influence of back plate material on the ballistic performance of the armor structure for bi-layers ceramic/metal configuration (ceramic front face and metal back plate) was investigated for Al6061-T6 and 4340 steel materials under same thickness and areal density. In the second section, the effect of removing half thickness of the metal constituent from the back plate and placing on the front face was investigated for both Al6061-T6 and 4340 steel materials. Finally, the influence of adhesive thickness on the ballistic performance of the armor structure was investigated. Perforation response of the armor structures were examined in terms of residual velocity of the projectile and damage mechanisms of the armor structure.
