Experimental Analysis of Tensile Mechanical Properties of Sprayed FRP

Abstract EN

To study the tensile mechanical properties of sprayed FRP, 13 groups of specimens were tested through uniaxial tensile experiments, being analyzed about stress-strain curve, tensile strength, elastic modulus, breaking elongation, and other mechanical properties.

Influencing factors on tensile mechanical properties of sprayed FRP such as fiber type, resin type, fiber volume ratio, fiber length, and composite thickness were studied in the paper too.

The results show that both fiber type and resin type have an obvious influence on tensile mechanical properties of sprayed FRP.

There will be a specific fiber volume ratio for sprayed FRP to obtain the best tensile mechanical property.

The increase of fiber length can lead to better tensile performance, while that of composite thickness results in property degradation.

The study can provide reference to popularization and application of sprayed FRP material used in structure reinforcement.
