Nilai kekuatan tarik material komposit berpenguat serat daun agel dengan variasi penggunaan jenis matrik, orientasi arah serat, dan tambahan filler sebagai penguat masih belum dikaji hingga saat ini. Melalui penelitian ini dilakukan pengkajian pengaruh matrik epoxy polyester, serta susunan 00 900, berupa serbuk kayu terhadap nilai agel. Proses fabrikasi melalui metode hand lay-up bentuk ...

Biological lay theories of race have proven to have pernicious consequences for interracial relations, yet few studies have examined how intergroup contact itself (particularly with those who naturalistically challenge these conceptions) affects beliefs about race.

This research includes the preparation of polymeric composites by (Hand lay-up method) unsaturated polyester resin as a matrix material and (iron, copper) particles strengthening materials with different weight ratios (5%, 10%, 15%, 20%). The hardness impact strength properties are studied before after immersion in (NaOH) solution (HCl) at normality (0.3N) for period one (30 days). results show...
