A study of two dimensional braided composites
A microstructure model of 2-D braided composite is developed. The fiber volume and crimp angle are evaluated by this model and are compared with experimental results. The maximum fiber volume fraction is also obtained. Effective stiffness of 2-D braided composite is obtained in a close form by the …

Characterization of damage mechanisms and behavior in two-dimensionally braided composites subjected to static and fatigue loading
In the present research project, four braided composite architectures consisting of graphite fibers in an epoxy matrix were tested under static and fatigue loading conditions to determine damage mechanism types and progressions. The braided architectures consisted of straight axial fiber bundles, …

Combined Tension-Torsion Loading of Braided Composite Structures
Braided composites are a class of composite materials. They feature an inter-woven structure that improves structural stability and damage tolerance. Presently, braided composites under tension and torsion loading have been studied individually. Mechanical behaviour of braided composites under …

Composite circular braid mechanics
Braided composites find many diverse applications in modern technology and tailoring the mechanical properties of these structures has become increasingly important. This thesis will examine one class of circular braids encompassing an elastic core. By hypothesizing four modes of operation and …

Biomimetic composite structure to simulate tendon performance
… to simulate the crimp in natural tendon. The composites were manufactured with the polymer matrix in solution form. A solution of the polyurethane and tetrahydrofuran was used to coat the fibers using a single-tow coating device. The effect of structure of the composite on the mechanical …

Energy Absorption and Progressive Failure Response of Composite Fuselage Frames
… by resin transfer molding into a 2x2 2D triaxial braided composite preform made of AS4 graphite yarns. Frames of both materials exhibit fractures at the pint of load application and at selected locations around the circumference, but the delamination prevalent in the tape layup frames is not …
