The Impact Characteristics of Fabric Reinforced Hybrid Composites

Abstract

In this research, the impact behavior of hybrid composite materials subjected to low-velocity impact using the drop-weight installation was investigated. For this study were manufactured eight hybrid materials. All the materials were tested to 90J impact energy. The effect of fabric types used in outer layers on impact performance was studied. The impact characteristics of hybrid materials with G1 glass fabric sheets were compared with those of hybrid materials with G2 glass fabric sheets. The damage surfaces of hybrid laminates were examined by visual investigation. The results obtained showed that the using of G2 glass fabric in structure of hybrid materials improved considerable the impact characteristics.

Fiber Orientation and Fillers Effects on Specific Heat of Fabric Reinforced Hybrid Epoxy Composites

“…In order to obtain the hybrid fabric M, it was used a carbon aramid fiber mixed fabric with 205 g/m 2 specific density, whose weave geometry represents an alternated carbon fiber by two aramid fibers in the weft direction and alternated aramid fiber by two carbon fibers in the warp direction. Each second aramid fiber in the weft direction of mixed fabric was replaced by a tin covered copper wire with diameter of 0.2 mm and a glass fiber with linear density of 200 tex [21][22][23].…”

Thermomechanical and Electrical Properties of Fabric Reinforced Laminates with Filled Stratified Epoxy Matrix

“…For this study epoxy resin was used as matrix and various fabrics as reinforcement in order to obtain stratified materials with different properties. A special type of fabric was realized and was used as medial layer [18,19]. Starting with a hybrid fabric made of aramid and carbon fiber tows in geometry 2×1 on weft direction and 1×2 on warp direction, each second aramid tow of the weft was replaced with a glass fiber tow together with a 0.2 mm diameter wire of tin covered copper, as it can be seen in figure 1.…”

An Experimental Study on the Low Velocity Impact Behavior of Hybrid Epoxy Composites

“…The microscopic images of the cross sections of hybrid laminates are showed in Figure 1, and the plies configuration is presented in Table 1. All hybrid epoxy laminates were made of 17 fabric plies, whose medial ply is a lamina of hybrid fabric [35][36][37]. In order to increase the fiber adherence, which is important for fiber-matrix interface quality, the used plain weave fabrics were treated with three types of solutions as detergent, sodium hydroxide and perchloric acid.…”
