Water absorption is done with ASTM C - 272. With the variation of fiber volume fraction of 0 %, 5 %, 10 %, 15 %, 20 % and 30 %, and also variations of the direction of unidirectional fibers, woven and random. Where the test specimens were weighed with a digital scale with a precision of 0.01 grams and then the specimens were kept for 7 x 24 hours, after which the composite is weighed again to d…
Composite is a combination of two or more materials which are arranged in a certain way to get new properties on the material results. Making the polyester composite reinforced arenga pinnata merr fiber with coconut shell powder filler is one way to get new material properties. This study aims to determine the nature of the bending strength and impact toughness of reinforced polyester composite…
