The Impact

The study presents the need for instrumented testing to optimizing materials against impact forces. The objective of the study is how the impact behaviour of composite materials is investigated by slow and high speed impact tests. Instron Dynatup 9250HV and Instron Dynatup 8150 Impact test machines (Fig.1.) are used which are located in TUBITAK-MRC, Materials Institute , Impact Test Laboratory". The damage process in composite materials under low and high velocity impact loading and the impact energy-displacement properties of the composite materials were investigated. Composite samples were produced by woven fabrics. The results are given as graphs and tables. The Impulse Data Acquisition software is used to send the data to computer.

The Impact

Modification of polymers with fillers provides the possibility of changing their physical and mechanical properties. The goal of the study is a comprehensive analysis of the effect of nanodispersed additives and other powdery substances on the strength of multilayer composite materials (CM). A series of multilayer composite specimens based on fiberglass and carbon fabric was made with the addition of fillers in a concentration of 1 and 3 wt.% to an epoxy polymer matrix. Nanopowders of silicon dioxide Tarkosil (T20, T50, T80, T110), fine powders of copper, collagen and cellulose fibers were used as fillers. Two types of tests, i.e., for compression and for impact were carried out. The introduction of nanopowders into CM changes their strength properties: the samples added with T110 nanomaterial withstand the maximum compressive load at a concentration of 1 and 3 wt.%. The results of impact tests of the samples with fillers and computer simulation of the impact and punching of the samples using the ANSYS/LS-DYNA software product, are presented. A method for numerical simulation of the impact process has been developed, which provides studying the dynamics of deformation and fracture of multilayer samples. Impact tests of the samples carried out at different values of the impact velocity (from 380 to 450 m/sec) revealed either puncture of the CM plates or damage such as delamination and splitting. In the impact test of multilayer specimens of composite materials with fillers added to the epoxy polymer matrix, the interlayer defects appeared in the form of delamination; samples without additives were pierced through under the impact. The experimental data on the degree of damage to multilayer plates after the impact matched the results of computer simulation.

Current Scenario

The uncertain climatic changes-related issues in the recent times has led an apprehension for all automotive makers to develop innovative composite materials to reduce vehicle’s fuel consumption. Hence, this review article has given special attention toward the factors that motivated several automakers to undergo research on biocomposites as it plays an important role for biodegradability and sustainability across the globe. In particular, cellulose nanofibers-reinforced composites are the main research focus in the current scenario which can be applied for different automotive applications with numerous advantages and abundant accessibility. Polypropylene (PP) is the emerging polymer in the automotive industry, and many researchers are now mainly focusing their research on PP-based composites which can serve as a boon for different environmental problems faced by the current scenario as depicted by Figure 1. It also reported the recent advancement on the development of innovative composite materials by different automakers with regard to finding suitable actions for reduction of fuel consumption to the recommended confines.
