Load Conditions

Three-dimensional integrated woven spacer sandwich composites have been widely used as industrial textiles for many applications due to their superior physical and mechanical properties. In this research, 3D integrated woven spacer sandwich composites of five different specifications were produced, and the mechanical properties and performance were investigated under different load conditions. XR-CT (X-ray computed tomography) images were employed to visualize the microstructural details and analyze the fracture morphologies of fractured specimens under different load conditions. In addition, the effects of warp and weft direction, face sheet thickness, and core pile height on the mechanical properties and performance of the composite materials were analyzed. This investigation can provide significant guidance to help determine the structure of composite materials and design new products according to the required mechanical properties.

And Performance

A novel kind of environmentally friendly composite materials containing upper part of rice straw segments (URSS), poly (vinyl alcohol) (PVA) and waste paper (WP) were prepared by hot-pressing at 140°C for 10 min. The tensile strength, tensile elongation and hardness of composites were measured. Results showed that the tensile strength and the strength at tensile break of the composites first increased and then decreased with increasing PVA content. Tensile strength was higher than the strength at tensile break at different PVA contents, indicating that URSS/PVA/WP composite materials had certain toughness. Otherwise, URSS/PVA/WP composite materials had higher tensile strength than URSS/PVA composites. The tensile strengths of them were respectively 9.25 MPa and 3.9 MPa when prepared at PVA content of 40%. The hardness of composites lay between 90 and 96. Negligible difference exists in every composite.

ABSTRACT Aim The aim of this article is to evaluate the influence of finishing and polishing techniques on the surface roughness and microhardness of two composite resins with two different types of polishing systems. Materials and methods A total of 30 disk-shaped specimens of nanocomposite Filtek™ Z350 and Ceram-X® were prepared. They were divided into three groups. The control group (n = 10) received no finishing and polishing. The remaining specimens were divided into two groups, and they received polishing and finishing either with PoGo or Sof-Lex system. After the polishing procedures, average surface roughness (Ra) was assessed with a surface profilometer. The microhardness was determined using a Vickers hardness test. The data were tabulated and analyzed. Results The smoothest surfaces were noticed with the control group (Mylar strips) in both composite materials tested. The PoGo one-step polishing system showed significantly better surface roughness compared with the Sof-Lex polishing system. The microhardness did not show any significant variations after finishing and polishing. Conclusion It can be concluded that the use of PoGo® onestep polishing system resulted in smoother surface with both composite materials studied compared with the Sof-Lex system. The finishing and polishing system had little influence on the surface microhardness. Clinical significance The finishing procedure and polishing system can affect the physical properties and performance of resin composites. How to cite this article Alfawaz Y.
