The influence of chitosan impregnation on the tensile and flexural strength of the short coir fiber reinforced polyester composites were studied in this investigation. The chitosan fillers were dispersed in polyester matrix, and laminates were prepared by reinforcing coir fibers in chitosan –polyester matrix. The composites were fabricated by varying filler content, fiber content and fiber length in three levels and their influence on tensile and flexural strength of the composites were studied. The composites with fiber length 30 mm, filler content 4% and fiber content 25% showed better values tensile (23 MPa) and at the same time the flexural strength (28MPa) of the composite was observed to be better with fiber length 30 mm, filler content 4 % and fiber content 25%.

In this article, a kind of SMC artificial marble was prepared. In order to enhance the mechanical properties and prolong the using life of SMC artificial marble, some effects such as fiber content, filler content and molding temperature etc. on the mechanical properties were carefully studied, too. Results showed that the increase of fiber content could improve the impact strength of SMC artificial marble when the fiber length was 10mm and the increase of filler content would decrease the flexural strength of SMC artificial marble. And the molding temperature at the range of 130°C ~ 160°C had little influence on the mechanical properties of SMC artificial marble. Comparing with natural marble and casting marble, SMC artificial marble owed superior overall performance and it was much more suitable for industry production.

This paper evaluated the effect of fiber length on the mechanical and physical performance of coir fiber reinforced cement-albumen composites (CFRCC). Albumen protein was added as a binder and the coir fibers with the lengths of 0, 2.5, 5, 10 and 20 mm was used as partial replacement of the cement mixture. Flexural and compressive strength, bulk density, moisture content and water absorption were investigated. The experimental investigations reveal that increasing in length of fiber augment the flexural strength. Incorporation of long fiber into the cement paste however, decreased the workability and thus introduced voids which results in low density. In fact, the water absorption and moisture content were also increased.

Coir-polypropylene composite was developed by the addition of coir fiber treated with 1.7 M NaOH solution for 24 hours at fiber loading 0 – 30 wt. % for automobile application. The fibers were cut to different length of 20 -50mm. Samples produced were subjected to test to examine tensile and flexural strengths and moduli, impact strength and hardness. Microstructural analysis was also carried out. Results obtained reveal rise in tensile strength with increasing fiber proportion up to 15 wt. % before a decline down to 30 wt. %. Increasing fiber length was observed to contribute to appreciation in strength up to 40 mm. Tensile modulus (TM) trended upward with in increased fiber loading up to 30 wt. % for length from 20 to 40 mm and for fiber cut to 50 mm, TM appreciated up to 15 wt. % before eventual depreciation. Results of flexural strength and modulus showed that flexural strength rose with increasing fiber loading up to 30 wt. % for coir fibers cut to 20 to 40 mm. Coir cut to 50 mm, gave increase up to 15 wt. % before eventual decrease in value. Flexural modulus rose from 0 to 30 wt. % for all fiber length except when 50 mm length was incorporated into the composite resulting lower modulus when compared with the ones recorded for coir of 40 mm length.

Purpose The purpose of this paper is to study the effects of fiber length and content on properties of E-glass and bamboo fiber reinforced epoxy resin matrices. Experiments are carried out as per ASTM standards to find the mechanical properties. Further, fractured surface of the specimen is subjected to morphological study. Design/methodology/approach Composite samples were prepared according to ASTM standards and were subjected to tensile and flexural loads. The fractured surfaces of the specimens were examined directly under scanning electron microscope. Findings From the experiment, it was found that the main factors that influence the properties of composite are fiber length and content. The optimum fiber length and weight ratio are 15 mm and 16 percent, respectively, for bamboo fiber/epoxy composite. Hence, the prediction of optimum fiber length and content becomes important, so that composite can be prepared with best mechanical properties. The investigation revealed the suitability of bamboo fiber as an effective reinforcement in epoxy matrix. Practical implications As bamboo fibers are biodegradable, recyclable, light weight and so on, their applications are numerous. They are widely used in automotive components, aerospace parts, sporting goods and building industry. With this scenario, the obtained result of bamboo fiber reinforced composites is not ignorable and could be of potential use, since it leads to harnessing of available natural fibers and their composites rather than synthetic fibers. Originality/value This work enlists the effect of fiber length and fiber content on tensile and flexural properties of bamboo fiber/epoxy composite, which has not been attempted so far.

Fiber-reinforced asphalt mixture has been widely used in pavement engineering to not only prevent asphalt binder leakage but also improve engineering properties of asphalt mixture. However, the research on three key parameters, namely fiber type, fiber length, and fiber content, which significantly affect the performance of fiber-reinforced asphalt mixture, have seldom been conducted systematically. To determine these three key parameters in the support of the application of fibers in mixture scientifically, three commonly used fibers were selected, basalt fiber, polyester fiber, and lignin fiber, and the testing on fibers, fiber-reinforced asphalt binders, and fiber-reinforced asphalt mixtures was conducted afterwards. The results showed: the favorable fiber type was basalt fiber; the favorable basalt fiber length was 6mm; the engineering properties including high temperature stability, low temperature crack resistance, and water susceptibility were clearly improved by the added basalt fiber, and the optimum basalt fiber content was 0.4 wt.%. The obtained results may be valuable from a practical point of view to engineers and practitioners.

Steel Deck

The crack initiation and life prediction of fiber-reinforced asphalt concrete (FRAC) surfacing for steel bridge decks under a cyclic vehicle load are analyzed from the perspective of damage mechanics. The damage field and the stress and strain field evolution rule of a composite beam in fatigue test are studied, and a fatigue failure criterion is proposed for steel deck FRAC surfacing. Bending fatigue tests are performed on composite beams composed of a steel deck and polyacrylonitrile (PAN)-fiber-reinforced Gussasphalt (GA), i.e., GA-PAN, concrete surfacing under different fiber content and temperature conditions. The damage evolution characteristics of GA-PAN concrete surfacing over the steel deck with different fiber lengths and volume ratios are predicted by analyzing the fatigue life equations. The results show that the steel bridge deck FRAC surfacing model can reflect the comprehensive influence of the fiber content and length on the fatigue performance of steel bridge AC. Specifically, a lower temperature results in the fiber more synergistically affecting the fatigue resistance of AC. Theoretically, the service performance of asphalt concrete increases with the increase of fiber length and content. The optimum fiber length and volume ratio of GA-PAN are found to be 9 mm and 0.46–0.48%, respectively, considering the construction workability.
