The plate of a pultruded fiber-reinforced polymer or fiber-reinforced plastic (FRP) profile produced via a pultrusion process is likely to undergo local buckling and cracking along the fiber direction under an external load. In this study, we constructed a pultruded glass-fiber-reinforced polymer-light wood composite (PGWC) profile to explore its mechanical performance. A rectangular cross-sect...

Many secreted signaling molecules are synthesized as precursors that undergo multiple maturation steps to generate their mature forms. The Saccharomyces cerevisiae mating pheromone a-factor is a C-terminally isoprenylated and carboxylmethylated dodecapeptide that is initially synthesized as a larger precursor containing 36 or 38 amino acids. We have previously shown that the maturation of a-fac...

Natural fibers have been used to reinforce materials for many years. More currently they have been employed in combination with plastics. Many types of natural fibers have been investigated for use in plastics including flax, hemp, jute, cotton and banana. Natural fibers have the advantage that they are renewable resources and have marketing appeal. These agricultural wastes can be used to prep...

A new analytical method to predict the torsional capacity and behavior of R.C multi-cell box girders strengthened with carbon fiber reinforced polymer (CFRP) sheets is presented. Modification was done on the Softened Truss Model (STM) in the proposed method; the concrete torsional problem is solved by combining the equilibrium conditions, compatibility conditions and constitutive laws of materi...

امروزه تقویت سازه ها یکی از شاخه های مهم در مهندسی عمران است. در جاهای مختلف سازه هایی وجود دارند که هنوز عمر مفید خود را به پایان نرسانده اند ولی به دلایل مختلفی از قبیل عوامل مخرب محیطی به قسمت های مهم سازه ای آسیبهایی رسیده است و یا سا زه هایی هستند که باری بیش از بار طراحی به آنها وارد میشود یا برخی از سازه ها هستند که در اجرای آنها از مصالح نامناسب استفاده شده است و یا اشتباه دیگری حین اجر...

The compressive response of polymer matrix fiber reinforced unidirectional composites (PMC’s) is investigated via a combination of experiment and analysis. The study accounts for the nonlinear constitutive response of the polymer matrix material and examines the effect of fiber geometric imperfections, fiber mechanical properties and fiber volume fraction on the measured compressive strength an...

Composite materials are finding increasing application in mechanical systems because of their desirable physical characteristics compared with metals; for example, high strengthand stiffness-to-weight ratios, and the potential for constructing complex shapes without joints or extensive machining. In addition, the dynamic behaviour of composite structures can be manipulated by judicious selectio...
