In this study, plastics such as glass fiber reinforced plastic (GFRP), polystyrene (PS), polycarbonate (PC), polypropylene (PP), polyvinyl chloride (PVC) were selected, and the fire risk associated with them was investigated using a cone calorimeter, as per ISO 5660-1. These values were measured to comprehensively predict the fire risk by Chung’s equations- Ⅱ. Standard materials (PMMA) were used to standardize the fire hazard assessment, and the fire risk was classified and evaluated by new Chung’s equations-III and Chung’s equation-IV. The fire performance index-II of Chung’s equations-Ⅱ showed that PVC had the highest FPI-II of 32.04 s<sup>2</sup>/kW, whereas PS had the lowest FPI-Ⅱ of 0.07 s<sup>2</sup>/kW. From the viewpoint of FGI-Ⅱ, the lowest fire growth index-Ⅱ was 0.09 kW/s<sup>2</sup> for PVC, and the highest fire growth index-Ⅱ for PS was 3.41 kW/s<sup>2</sup>. The FPI-Ⅲ of Chung’s equations-Ⅲ had the lowest fire performance index-Ⅲ for PS (0.02) and highest fire performance index-Ⅲ for PVC (89). The FGI-Ⅲ had the highest fire growth index-Ⅲ of 20.1, and PS and PVC were found to be the safest materials with an FGI of 0.5. The FRI-Ⅳ of Chung’s equation-Ⅳ was in the following order: PS (100.5) ≫ PP (2.43) > PC (1.12) > PMMA (1.0) > FRP (0.19) > PVC (0.01). Therefore, it was concluded that the fire risk associated with PVC is lowest, whereas that associated with PS is highest.

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.

<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>
