The addition of EG and CNTs to PET did not have influence on the amorphous arrangement of unfilled PET, while the loading of Mg(OH 2/EG and Mg(OH 2/CNT fillers favoured the PET crystallization.
According to the real time X-ray diffraction, the nanocomposite showed the weak ordering of PP crystals than the unfilled PP in the load-extension plateau region of elongation.
This work examines both stress-life (S N) fatigue behavior and the fracture behavior of unfilled PEEK under tension tension loading in circumferentially grooved round bar specimens with different elastic stress concentration factors.
The size of crystal aggregates decreases with SWCNT loading, however, in reference to the unfilled polyethylene, the three-dimensional growth geometry extracted from the Avrami exponents remains unchanged up to 2 wt%.
The effect of MS loading on the swelling ratio of unfilled and MS-filled NR composites using different microsizes: 10, 20, and 75 μm, is presented in Figure9.
Accelerated aging behavior at 70°C and 100°C for 96 h of MS-filled and unfilled NR composites is also affected by the loading and microsize of MS particles.
Two approaches are readily thinkable to overcome this issue: increasing the single-atom loading efficiency14,15,16,17 and relocating abundant atoms to unfilled positions18,19.
Based on the compression tests, a synergistic effect that the foam filled sandwich panels have a greater load carrying capacity compared to the sum of the unfilled specimens and the filled polyurethane block is found.
The aging behavior of samples containing different loading and microsize particle of MS-filled and unfilled NR composites shows reduction of tensile strength, tear strength, elongation at break, and modulus at 100%, 200%, and 300% elongation.
The strongest pattern in common among the six unfilled combinations is that only one has a strong negative loading on Principal Component 1.
A series of tests were conducted on circular CFST, unfilled circular hollow section (CHS) steel tube and plain concrete specimens loaded with local bearing force.
