Presents the results of a study of the effect of the final curing temperatures on the complex of properties of the developed epoxy binder grade VSE-65 and glass-fiber-reinforced plastic based on it. It was found that with a decrease in the final curing temperature, the residual heat effect increases and, in turn, a decrease in the conversion of epoxy groups occurs. Presents the results of a comparative analysis of VKG-6 glass-carbon plastic samples prepared by vacuum infusion and pressure impregnation. Based on the results of the analysis, it has been established that the technologies make it possible to realize the required level of physical and mechanical properties.

This paper deals with the fabrication of test specimens of Glass fiber reinforced plastic (GFRP), Carbon fiber reinforced plastic (CFRP), Glass-Carbon fiber reinforced plastic (G-CFRP) and Carbon glass fiber reinforced plastic (C-GFRP) by using hand layup method. The low velocity point load setup was fabricated and fixed in the milling machine by using cam pointer arrangement. The specimens have been subjected to the low velocity point load for specific duration by exposure time such as 0,15,30,45 and 60 minutes. Then impact and DMA tests are also carried out for the above specimens. From the DMA test results it was found that the storage modulus and loss factor of GFRP specimen are high compared with others. Izod impact test result shows that impact strength of G-CFRP specimen is high. The flexural results reveals that among the four types of laminates CFRP gives higher order of flexural strength and modulus compared to the others

A previously proposed micromechanical formula, aiming to predict the vaporization energy Qv of composite materials as a function of fiber and matrix properties and fiber volume ratio, was assessed. The experimental data, obtained on glass fiber reinforced plastic panels with different fiber contents cut by a medium power CO2 cw laser, were treated according to a procedure previously suggested, in order to evaluate Qv. An excellent agreement was found between experimental and theoretical Qv values. Theory was then used to predict the response to laser cutting of a composite material with a fiber content varying along the thickness. The theoretical predictions indicated that, in this case, the interpretation of the experimental results may be misleading, bringing to errors in the evaluation of the material thermal properties, or in the prediction of the kerf depth. Some experimental data were obtained, confirming the theoretical findings.

Alternative Materials

<span class="longtext"><em><span>GFRP composite is one of the alternative materials that the most common as a replacement for metal. This material has a light weight, easy to shape, good strength, and the production cost is relatively cheaper. This study aims to investigate the effects of fiber diameter variation of mechanical behavior, particularly on the load of high strain rate impact. The application of impulse momentum theory in the elastic region is the basic science for this case. The AGC apparatus is equipment that used for this test because it could generate the high strain wave rate in the single direction loading. Specimen is placed in the position of tight end against the end of the input bar. The results showed that the increase in fiber diameter variations affect the value of E that is produced. Thus, it is become a recommendation for the use of this material in certain circumstances.</span></em></span>
