The studies of composites are being focused on natural fiber composites as potential alternative materials to substitute fiber glass composites. Beside mechanical advantages, natural fibers have main superiorities namely biodegradable, naturally produced, and sustainable. The objectives of this research are to create and analysis the strength and mechanics characteristics of bamboo fibers composite after cyclic loading. Bamboo-polyester laminates constitute of 60% (by volume) bamboo flour-filled polyester and 40% (by volume) bamboo fiber and are fabricated into 3 layers by 2 order of stacking: 0o/30o/0o and 30o/0o/30o. By subjecting cyclic load 20% and 50% of bending stress ???b, strength and stiffness of composites can be analysed. The results of this research showed that under 20%???b cyclic loads, both composites laminae 0o/30o/0o and 30o/0o/30o experience no degradation of strength and stiffness up to n=104 cycle. After introducing 50%???b load, however, the 0/30/0 laminae performed debonding delaminating endurance higher than that of 30/0/30 laminae. |
