“…However, the tensile strength continued to increase with the hot pressing time of 50 min. The mechanical strengths of the laminated composite in this study were comparable to the mechanical properties of the composites reinforced with glass fibers or even carbon fiber [27,28,29] and much greater than those of injection molding paper-fiber composites [30]. The high mechanical strengths were obtained because the paper fiber content was higher than 64.6 wt % and paper fiber aspect ratio was not mechanically reduced in the laminated composite.…”

Recycled newspaper (NP) shows excellent potential as a reinforcement for polymer composites. Herein, high-strength laminated composites were prepared by using NP laminas as reinforcement and high-density polyethylene (HDPE) films as matrix. Physical and mechanical properties of the laminated composites were measured. It was found that the flexural strength of the composites had a good linear relationship to its density, with R2 = 0.9853. The flexural and tensile strength of the composites at the maximum density (1.40 g/cm3) reached up to 95.6 ± 2.4 MPa and 99.4 ± 0.8 MPa, respectively. SEM results showed that NP layer inside the composite became compact at the hot pressing time of 40 min, because the melted HDPE permeated into the NP layers to bond the NP fibers. Quantitative description of the composite porosity was conducted according to the density of the composite. The 24-h water absorption of the composite was highly related to its porosity, with R2 = 0.8994. This study reveals that density of laminated composites is an important parameter, which could be used to forecast the mechanical strength, and its derived value, porosity of the composites, could be used to predict the water absorption behavior of the composite.

“…Ocorreu interação física e química entre a matriz e o reforço, sem o uso de agentes de acoplamento, o que foi confirmado na microscopia eletrônica por varredura (MEV), a qual mostrou que as fibras estavam bem envolvidas com a matriz de polietileno. As análises térmicas de termogravimétria (TGA) mostraram a extensão da degradação e a estabilidade térmica do material, onde a decomposição das amostras testadas ocorreu no intervalo de 30 a 1400ºC (KHAN et al, 2016(KHAN et al, , p. 1078.…”

“…O módulo de flexão na direção transversal aumentou com o aumento das camadas de fibra de carbono e com uma variação de 64% na resistência à flexão entre o menor e o maior número de camadas. A melhora foi devido à colocação adequada da fibra de carbono na direção transversal, da cura integral e da adesão das camadas da fibra de carbono com a matriz de polietileno (KHAN et al, 2016(KHAN et al, , p. 1079.…”

Review: compósitos poliméricos para substituir madeira aplicada em semirreboques -fatores que influenciam no comportamento mecânico 1 Cezar de Mattos² Edson Luiz Francisquetti 3Resumo A busca por materiais leves para aplicação automotiva é crescente, e os compósitos são uma opção para os veículos de carga. A redução de massa e durabilidade são fatores importantes, quando competitividade é avaliada. Atualmente, a carroceria do semirreboque tipo graneleiro é confeccionada em aço e revestida com madeira. A substituição da madeira por um material compósito pode ajudar no aumento da carga líquida e também na vida útil do semirreboque. No entanto, desenvolver um compósito polimérico reforçado por fibras com características similares as da madeira não é uma tarefa fácil. Nessa lógica, este artigo tem como objetivo fazer uma revisão bibliográfica, avaliando os fatores que interferem no comportamento mecânico desses compósitos poliméricos reforçados com fibra. Através da análise dos manuscritos, foi possível determinar que a fração volumétrica, as orientações e as características físicas das fibras, bem como a adesão interfacial, são fatores que influenciam significativamente no comportamento mecânico dos compósitos. Palavras-chave: Compósitos poliméricos. Semirreboques. Propriedades mecânicas. AbstractThe search for lightweight materials for automotive applications is increasing and composites are an option for cargo vehicles. The reduction of mass and durability are important factors, when competitiveness is evaluated. Currently, the body of the bulk semi-trailer is made of steel and coated with wood. The replacing of the wood by a composite material can help in increasing the net load and also the service life of the semi-trailer. However, developing a fiber-reinforced polymer composite with wood-like characteristics is not an easy task. In this logic, this article aims to make a bibliographical review, evaluating the factors that interfere in the mechanical behavior of these fibers reinforced by polymer composites. Through the analysis of the manuscripts, it was possible to determine that the volumetric fraction, orientations and physical characteristics of the fibers, as well as interfacial adhesion, are factors that influence significantly the mechanical behavior of the composites.

This work aimed to investigate the effect of adding short fibers of Pinus and Eucalyptus, in different granulometry (24 and 200 mesh) and concentration (0–20 m/m), combined with processing aid Struktol TPW104 (S) in obtaining of high‐density polyethylene (HDPE) composites. Overall, obtaining composites from short fibers caused relevant changes in the HDPE matrix, such as thermal stability, moisture barrier. In comparison to pure HDPE, the composites incorporated with 20% m/m of fibers, regardless of the type, decreased the melting temperature to 128°C and a wider crystallization temperature range. Another significant observation was the improvement of composites mechanical profile after adding the additive, the highest values were obtained for composites HDPEL20PS (35%—TS e 651%—EM) and HDPEL20ES (42%—TS e 681%—EM), showing good interaction and compatibility, according to scanning electron microscopy (SEM) images. The same was verified with the mechanical results of flexion and impact. Therefore, the use of short fibers and processing aid was successful providing augmented mechanical properties and thermal stability, without negatively affecting their essential properties for industrial applications.
