Weibull analysis of strength-length relationships in single Nicalon SiC fibres

Comparative Studies of Mechanical and Interfacial Properties between Jute and Bamboo Fiber-Reinforced Polypropylene-Based Composites

“…Similarly, the saturation point was also checked by the number of fragments against displacement. The critical length (l c ) was then measured using the formula: l c ¼ 4l f /3, where l f is the average fragment length which was calculated as the monitored length (25 mm) divided by the number of breaks observed within that length of the experimental fragment length distribution, according to Kelly-Tyson model [19][20][21]. To find out the critical length, the number of fragments was counted.…”

“…A cross-head speed of 1 mm/min was used. The interfacial shear strength (IFSS) of the composites was calculated from both the Kelly-Tyson and Drzal equations [20][21][22][23]. Based on the force balance on a micro-mechanical model, Kelly and Tyson showed that IFSS is given by:…”

“…The SFFT method has several advantages such as: simple specimen handling, replication of the stress-transfer characteristics in real composites, convenient monitoring of failure processes directly, and the fact that critical length is sensitive to the level of fiber-matrix adhesion. Interface scientists regard this test as a reliable method for the determination of interfacial properties of the fiber-reinforced polymer composites [15][16][17][18][19][20][21][22][23].…”

Interfacial Properties of Two-Carbon Fiber Reinforced Polycarbonate Composites Using Two-Synthesized Graft Copolymers as Coupling Agents

“…In the determination of fiber tensile strength at a critical length, a direct fiber tensile test at such a short length may result in experimental difficulties (19). Hence, fiber strengths are usually determined first by measuring the macroscopic gauge lengths, and then with a subsequent extrapolation to such smaller gauge lengths using the Weibull weakest link rule (20).…”

Interfacial Aspects of Electrodeposited Conductive Fibers/Epoxy Composites using Electro-Micromechanical Technique and Nondestructive Evaluation

“…In determining the fiber tensile strength at the critical fragment length (usually less than 1 mm), a direct tensile test at such a short length can result in experimental difficulties. After fiber strength was usually determined at a measurable 2 mm in gauge length, it was subjected to subsequent extrapolation to a smaller gauge length using the Weibull weakest link rule (27,28). Tensile strength at a critical fragment length can be obtained as…”
