Effect of filler addition on the compressive and impact properties of glass fibre reinforced epoxy

Abstract

Flyash is incorporated in glass fibre reinforced epoxies to study their response to the filler addition. Low cost of flyash can reduce the overall cost of the component. Only very low volume fractions of filler are investigated in the present study. To obtain further clarification of the observed phenomenon, another abundantly available low cost material, calcium carbonate is incorporated in one set of the specimens. Compressive strength of the material is found to decrease, whereas steep increase in impact strength is observed by introduction of very small quantity of fillers. Specimens containing calcium carbonate are tested for impact properties only. Effect of specimen aspect ratio on the compressive strength values is also studied by testing specimens of three different aspect ratios. Scanning electron microscopic observations are taken to develop a better understanding of the phenomena taking place in the material system at microscopic level.

Evaluation of Mechanical Property on Palm/Coir Based Polymer Matrix Composites

“…Sreekala et.al [13] reported hybridization of glass fiber with oil palm fiber reinforced composites improved the mechanical strength. The hybridization of fly ash in glass fiber epoxy on compressive and impact properties studied [14]. The sisal and oil palm hybrid composites reinforced natural rubber composites were studied [15].…”

Influência da Espessura nas Propriedades Mecânicas de Compósitos Híbridos Interlaminares de Curauá / Vidro / Poliéster

“…Avaliou-se a densidade dos compósitos de acordo com a norma ASTM D792, usando um picnômetro, e o teor de vazios foi determinado a partir da norma ASTM D2734, com os seguintes valores de densidade das fibras de curauá e vidro, 1,38 e 2,54 g/cm 3 , respectivamente [9,10] . O teste de dureza Barcol (norma ASTM D2583) foi executado usando um durômetro da marca Bareiss, com dez medidas na superfície de cada laminado, e o ensaio de impacto (norma ASTM D256) em uma máquina de impacto Ceast, em corpos-de-prova não entalhados (6 para cada laminado) e com um martelo de 11 J. Realizou-se ensaio de flexão (norma ASTM D790) em oito corpos-de-prova de cada família usando uma EMIC DL3000 com célula de carga de 200 kN, e ensaio de tração (ASTM D3039, 8 corpos-de-prova para cada família), usando uma INSTRON-8801 com célula de carga de 100 kN, e velocidade de 2 mm/min, com extensômetro.…”
