A fiber-reinforced composite (FRC) is a composite building material that consists of three components: [1] [2] the fibers as the discontinuous or dispersed phase, the matrix as the continuous phase, and; the fine interphase region, also known as the interface.
Plant fibers are a promising area but they are subjected to degradation in the alkaline environment and elevated temperatures during cement hydration. [3] [4] In international literature, FRCMs are also called textile-reinforced concrete (TRC), textile reinforced mortars (TRM), fabric-reinforced mortar (FRM), or inorganic matrix-grid composites ...
This stretching or ‘straining’ action actually strengthens the material. This phenomenon is made possible through the development of multiple microscopic cracks, opposed to the single crack/strain softening behavior exhibited by typical fiber-reinforced concretes. It occurs in HPFRCCs as several fibers slip past one another.
The condition of a fiber-reinforced composite under applied tensile stress along the direction of the fibers can be decomposed into four stages from small strain to large strain. Since the stress is parallel to the fibers, the deformation is described by the isostrain condition, i.e., the fiber and matrix experience the same strain.
Thin fibers can have very high strength, and they can increase substantially the overall properties of the composite provided they are linked mechanically to the matrix. Fiber-reinforced composites have two types, and they are short fibre-reinforced and continuous fiber-reinforced. Sheet moulding and compression moulding operations usually use ...
Fibers have been used as reinforcement since ancient times. [4] Historically, horsehair was used in mortar [5] and straw in mudbricks. In the 1900s, asbestos fibers were used in concrete. In the 1950s, the concept of composite materials came into being and fiber-reinforced
