TL;DR: In this article, a B 4 C-TiB 2 composite with high strength of 866 MPa and modest fracture toughness of 3.2 MPa m 1/2 could be obtained using B 4C powder with a mean particle size of 0.50 μm and total metal impurity 0.3-0.5 wt.% (Al + Fe).
Abstract: B 4 C based composites with 20 mol% TiB 2 were fabricated by reaction hot-pressing of four different submicron size B 4 C powders with the addition of nanometer size TiO 2 and C powders at 2000 °C, and their mechanical properties were examined. A B 4 C–TiB 2 composite with both high strength of 866 MPa and modest fracture toughness of 3.2 MPa m 1/2 could be obtained using B 4 C powder with a mean particle size of 0.50 μm and total metal impurity 0.3–0.5 wt.% (Al + Fe). It seems that this extremely high strength is attributed to the fine-grained B 4 C microstructure, uniform dispersion of TiB 2 particles and improvement of fracture toughness.

TL;DR: In this article, the Weibull model is used to describe the intrinsic statistical nature of the fracture strength of high-performance filaments and the relationship between material properties and the parameters in the weibull models is discussed.
Abstract: The strength of high-performance filaments is a complex parameter which can not be fully described with a single value. The Weibull model is used to describe the intrinsic statistical nature of the fracture strength. Possibilities and limitations of the Weibull model are illustrated. The relationship between material properties and the parameters in the Weibull model is discussed.

TL;DR: In this paper, the authors investigated a new concept for designing composite structures comprising a lightweight concrete core sandwiched in between two steel plates which are interconnected by J-hook connectors and found that the hook connectors are capable of resisting tension and shear, and their uses are not restricted by the core thickness.

TL;DR: In this paper, a criterion for the minimum number of shear connectors required for steel and concrete composite beams in buildings was derived based on the ultimate strength of the members, and the relationship between the ultimate strengths of commonly used types of mechanical shear connector and composite beam is developed.
Abstract: Tests on twelve single span and one two-span continuous, full scale composite beams are described, and the results evaluated. The investigation was concerned with determining the minimum number of shear connectors required for steel and concrete composite beams in buildings. A thorough examination of the ultimate strength of members was made. A criterion for the minimum shear connector requirement was derived based on the ultimate strength of the members. Relationships between the ultimate strengths of commonly used types of mechanical shear connectors and the ultimate strength of a composite beam are developed. The deflection of members is shown to be larger for beams with the minimum recommended shear connection as compared to theoretical bending deflections, and the magnitude of these deflections is discussed.
