Biocomposites are promising candidates for some engineering applications owing to the growing environmental and economic challenges replace petrochemical-based polymers with biodegradable polymers. Herein, sisal fiber reinforced polylactic acid (PLA) composite specimens were fabricated using an injection molding machine without plasticizer. The weight percentage (wt%) of varied between 5% 20%. ...

Replacing nonrenewable polymers with renewable ones is desirable for packaging applications. For this purpose, a number of poly(glucaramides) were synthesized and tested for applications requiring water resistance. The polymers were prepared from the polycondensation of esterified glucaric acid and a diamine, the former being obtained from the oxidation of glucose, thus providing a renewable so...

The effect of moisture absorption and high temperature on the compressive strength of unidirectional IM7/977-2 carbon/epoxy resins have been investigated experimentally. The specimens were divided into 4 groups, and tested under 4 different conditions by varying the testing temperature and moisture parameters. The fiber orientation selected were 0o, ±45o and 90o...

this paper presents the results of analytical studies concerning the flexuralstrengthening of reinforced concrete beams by external bonding of high-strength lightweightcarbon fiber reinforced plastic (cfrp) plates to tension face of the beam. three groups of beamswere tested analytically and compared with existing experimental results. results of the numericalanalyses showed that, although addi...

Composite materials, comprised of fibre-reinforced polymers, offer a high strength-to-weight ratio, making them excellent for the building complex, lightweight structures in several industries, including marine industry. There is an improvement fuel efficiency and cost-effectiveness general component developments as result flexible design characteristics. Fibre-reinforced polymer (FRP) composit...
