Fiber Reinforced Polymer (FRP) made from synthetic fiber had been widely used for strengthening of reinforced concrete (RC) structures in the past decades. Due to its high cost, detrimental to the environment and human health, natural fiber composites becoming the current alternatives towards a green and environmental friendly material. This paper presents an investigation on the mechanical properties of bamboo fiber reinforced composite (BFRC) with different types of resins. The BFRC specimens were prepared by hand lay-up method using epoxy and vinyl-ester resins. Bamboo fiber volume fractions, 30%, 35%, 40%, 45% and 50% was experimentally investigated by conducting tensile and flexural test, respectively. Results showed that the tensile and flexural strength of bamboo fiber reinforced epoxy composite (BFREC) was 63.2% greater than the bamboo fiber reinforced vinyl-ester composite (BFRVC). It was found that 45% of bamboo fiber volume fraction on BFREC exhibited the highest tensile strength compared to other BFRECs. Meanwhile, 40% bamboo fiber volume fraction of BFRVC showed the highest tensile strength between bamboo fiber volume fractions for BFRC using vinyl-ester resin. Studies showed that epoxy-based BFRC exhibited excellent results compared to the vinyl-ester-based composite. Further studies are required on using BFRC epoxy-based composite in various structural applications and strengthening purposes.

Fibers of the giant bamboo (Dendrocalmus giganteus) are amongst the strongest lignocellulosic fibers. Although studies have been already performed, limited information exists on the mechanical properties of polymeric composites reinforced with continuous and aligned giant bamboo fibers. This work evaluates the tensile strength of this type of composite. Standard tensile specimens were fabricated with up to 30% of fibers aligned along the specimen length. The fibers were press-molded with a commercial polyester resin mixed with a hardener and cured for 24 hours at room temperature. The specimens were tensile tested in an Instron machine and the fracture surface analyzed by scanning electron microscopy. The tensile strength increased significantly with the amount of giant bamboo fiber reinforcing the composite. This performance can be associated with the difficult of rupture imposed by the fibers as well as with the type of cracks resulting from the bamboo fiber/polyester matrix interaction, which prevents rupture to occur.

In this paper, we attempted to prepare the binderless green composite using bamboo fiber and steam-exploded bamboo powder as matrix. The influence of molding conditions on their tensile behavior was investigated by changing the molding temperature, pressure and time. Except for the composites molded at low temperatures from 100°C to 120°C, their tensile strength decreased with increasing the molding temperature. When the molding time increased, their tensile strength decreased. Average tensile strength of the binderless bamboo green composite molded at 120°C and 10 MPa for 10 min was 170 MPa. The decreases in tensile strength of binderless composites molded at temperatures higher than 120°C may be responsible for the strength drop of the reinforcing bamboo fiber derived from thermal decomposition. In order to obtain detailed information about the adhesion behavior of bamboo powder and bamboo fiber, photomicrographs were taken of the fracture surfaces of the composites. The results show that molding condition, especially molding temperature, has a great effect on the mechanical properties of bamboo fiber reinforced binderless green composites.

Fiber reinforced polymer (FRP) is widely used in the construction industry for structural strengthening due to their outstanding mechanical properties. However, the production of synthetic fibers such as FRP is detrimental to the environment. Alternatively, natural fiber composite may be used as external strengthening material. This paper presents the potential of bamboo fiber composite plate (BFCP) to strengthen the reinforced concrete (RC) beams in flexure. The bamboo of species Dendrocalamus asper was used to produce the fiber and fiber-to-volume ratio was set at 2:5. The composite plate was fabricated by binding bamboo fibers with epoxy using a hand-lay-up method. The flexural and tensile strength of the BFCP was measured and all the beams were tested to failure under four-point bending test. It was found that BFCP exhibited a higher flexural and tensile strength compared to pure epoxy samples. Meanwhile, the RC beams strengthened using BFCP exhibited an increment of 10-12% in beam structural capacity compared to the un-strengthened beams. Bonding of BFCP in the flexure zone was able to divert the vertical cracks into diagonal at the edge of the composite plate. Findings from this work may serve as a useful guide to strengthen RC beams using a BFCP.

In this paper the composites made of cornstarch and PVA as matrix, bamboo fiber as reinforcement, glycerol and urea as mixed plasticizer were prepared through the extrusion molding. By physical methods, the effects of cornstarch, bamboo fiber, PVA and mixed plasticizer on the mechanical properties of composites were investigated. SEM was used to observe the influence of different content of mixed plasticizer in cornstarch. The results showed that an increase in mixed plasticizer content from 10% to 40% in cornstarch did improve the mechanical properties of the composites compared without mixed plasticizer, and when the mixed plasticizer (wt-glycerol: wt-urea=2:1) content was 30% to cornstarch, the composite showed the highest tensile strength and elongation rate. Composites made from 20% of bamboo fiber, 30% of cornstarch, 50% of PVA and 30% of mixed plasticizer to cornstarch gave the best tensile strength (15.8N). Glycerol and urea could permeate the cornstarch molecules and plasticize it under high temperature and shearing in the extrusion process.

Bamboo Fibers

This paper deals with the mechanical behavior of bamboo fiber-reinforced biodegradable composites (green composites). A starch-based, dispersion type biodegradable resin was used as matrix polymer, and this matrix was reinforced by long bamboo fibers which were extracted by a steam-explosion method. The experimental results showed that the developed green composites possessed the flexural and tensile strength of 263 MPa and 270 MPa, respectively. The mechanical properties of the green composites were evaluated as a function of fiber content. It is found that the observed tensile strength was slightly lower than that of estimated values from the rule of the mixture. This discrepancy might be related to the misorientation of the bamboo fiber in the composites and to that the final fracture of composites is also governed by the presence of weak bamboo fiber.
