Abstract
In this study, the tensile properties of Fiber Reinforced Plastics (FRP) using
natural fibers were investigated. Jute fibers were chosen as reinforcement.
Polypropylene was used as a matrix. Jute Fiber Reinforced Plastics (JFRP) was
laminated using a conventional hot press facility. The surface treatment using the
astringency of persimmon was performed on the jute fiber before molding. The
surface treatment using heat treatment to jute fiber in an oven was also
conducted. The static tensile and creep properties of jute fiber reinforced
composite were investigated.
As a result, the following conclusions are obtained.
(1) The treatment using the astringency of persimmon is effective to improve
the interfacial strength between jute fiber and the matrix and it decreases the
initial elastic strain in a creep test. (2) For a static tensile test, the treatment using
the astringency of persimmon increases the initial stiffness. The improvement
ratio decreases as the applied load increases. (3) The treatment using heating
fibers before molding has an effect in that it increases the tensile strength and
initial stiffness, because the treatment improves the interfacial strength between
the fiber and the matrix. (4) The effect of heat treatment is the highest in the case
where the temperature is 120 degrees centigrade and the time is half an hour.
Keywords: green composite, jute fiber, polypropylene, tensile properties, creep,
surface treatment, heat treatment.
1 Introduction
Glass Fiber Reinforced Plastics (GFRP) have been popular for many mechanical
parts. Because of their superior advantages, such as durability, high specific
strength, stiffness, GFRPs have been replaced instead of metals in many
