“…Incorporating other polymer materials also allows dynamic performance to increase, and, hence, the fatigue properties of the obtained composite material also increase. Varga and Bartha [35] demonstrated improved dynamic properties for short, glass fiber-reinforced PBT after incorporating cyclic oligomers (CBT-100), and the fatigue performance analysis indicated differences with conventional metal-type materials. Eftekhari et al [36] tested fatigue with variable amplitude, and a rigidity process in the first load cycle was observed.…”

The aim of this work was to show the evolution over time of the dynamic moduli in components made of Polybutylene Terephthalate reinforced with glass fiber when they are held to temperatures close to the glass transition temperature over time. For this purpose, PBT samples reinforced with short, glass fibers of Ultradur® material with 0%, 20%, and 50% in weight content were tested. Dynamic moduli showed an increment with glass fiber content showing a nonlinear behavior with the temperature. The evolution of storage modulus was depicted by means of a modified law of mixtures with an effectiveness factor depending on temperature and fiber content, whereas the evolution over time was obtained with a time–temperature transformation generated with the TTS Data Analysis software of TA-instruments for a given temperature. Storage modulus showed a linear relationship with glass fiber content when components were held to temperatures near to their respective glass transition temperature, obtained from the maximum of loss modulus curve with temperature. In summary, the value and evolution of dynamic moduli of PBT samples improved with glass fiber content, allowing us to increase the durability of components when they are submitted to high-temperature environments.

In this study, the effects of basalt fiber (BF) amount and initial fiber length on tensile, flexural and impact properties of poly (butylene terephthalate) (PBT)-based composites are studied. The effect of BF amount on thermomechanical and thermal properties of the composites is also investigated using dynamic mechanical analysis, differential scanning calorimeter and thermal gravimetric analysis. The BF is used at concentrations of 5, 10, 20 and 30 wt% and with different initial lengths of 3, 6 and 12 mm under constant loading of BF (20 wt%). According to the test results, the addition of BF improves the tensile strength and thermal stability of PBT at 20 and 30 wt% loading. Flexural strength and elastic modulus increase steadily as the added amount of BF increases. The addition of BF favors crystallization up to 10 wt% loading. No remarkable effect of initial fiber length is observed on the mechanical properties of the composites.

“…However, its disadvantages of low heat deflection temperature and high impact sensitivity limit its development for some applications and require significant improvement [ 23 , 24 , 25 , 26 , 27 ]. In general, calcium carbonate [ 28 ], glass fibers [ 29 , 30 , 31 , 32 ], carbon fibers [ 33 ], montmorillonite [ 34 ], and carbon nanotubes [ 35 , 36 ] are commonly used as PBT reinforcements [ 37 ].…”

As artificial marble is abundant and widely used in residential and commercial fields, the resource utilization of artificial marble wastes (AMWs) has become extremely important in order to protect the environment. In this paper, polybutylene terephthalate/artificial marble wastes (PBT/AMWs) composites were prepared by melt blending to maximize resource utilization and increase PBT performance. The research results showed that the filling of AMWs was beneficial to the improvement of PBT-related performance. X-ray diffraction analysis results indicated that after filling AMWs into the PBT matrix, the crystal structure of PBT was not changed. Heat deflection temperature (HDT) analysis results indicated that the HDT of PBT composites with 20 wt% AMWs reached 66.68 °C, which was 9.12 °C higher than that of neat PBT. Differential scanning calorimetry analysis results showed that heterogeneous nucleation could be well achieved when the filling content was 15 wt%; impact and scanning electron microscope analysis results showed that due to the partial core-shell structure of the AMWs, the impact strength of PBT was significantly improved after filling. When the filling amount was 20 wt%, the impact strength of the PBT composites reached 23.20 kJ/m2, which was 17.94 kJ/m2 higher than that of neat PBT. This research will not only provide new insights into the efficient and high-value utilization of AMWs, but also provide a good reference for improved applications of other polymers.
