PENGARUH VARIASI FRAKSI VOLUME KOMPOSIT POLYESTER-SERAT KULIT JAGUNG (Zea Mays) TERHADAP KEKUATAN IMPAK, BENDING, DAN TARIK

Abstract


 One of the engineering materials is Composite. Composite is a material formed from a combination of two or more matrials that have stronger mechanical properties than the. The composite consists of two parts: a matrix as a binder or a composite protector and a filler as a composite filler. Natural fibers are an alternative filler, and the corn husk fiber (Zea Mays) is one of the many natural fibers grown in the Tanah Laut area of South Kalimantan.From the result of the research, the effect of volume fraction on the composite has the fiber skin fiber which has the highest strength for the impact price that is on the fiber with the volume fraction of 1% 99% fiber polyester corn fiber fiber which has the impact price of 0.0338 joule / mm2. In the highest strength bending test that is on the composite with a fraction of fiber volume of 3% that has a bending power of 3,5775MPa. And in composite tensile test, volume fraction 4% fiber 96% polyester and 5% fiber 95% polyrster have the same value of highest strength that is tensile pull of 1,7991 MPa.

Effect of Volume Fraction hybrid composite duck feathers (Anas Plathycus Borneo) - Rat Purun Fiber (Eleocharis Dulcis) With Matrix Polyester On Tensile And Bending Strength

“…The increased volume fraction of duck feathers does not change the bending strength but instead experiences a decrease in bending strength [13]. Duck feathers cannot withstand large loads when combined with rat purun fibers into a hybrid composite [14].…”

Pengaruh Variasi Ukuran Partikel Batang Jagung Terhadap Konduktivitas Termal Dan Peredaman Suara Komposit Partikel Batang Jagung

“…Berkaca pada penelitian sebelumnya yang meneliti tentang "Pengaruh Fraksi Volume Komposit Polyester-Serat Kulit Jagung Terhadap Kekuatan Impak, Bending, dan Tarik" [10] yang menggunakan serat kulit jagung serta hanya melakukan pengujian sifat mekanik terhadap komposit itu, maka perlu dilakukan studi penelitian pengaruh cacahan batang jagung terhadap peredaman suara dan konduktivitas termal.…”
