“…Mats of PRF and films of PLA with 20%, 30%, and 40% (w/w) fibre content were stacked by hand onto a metal frame, as shown in Figure 3. 20,21 Through preliminary trial tests (A, B, and C), the time and temperature parameters were identified to produce high-quality PRF-PLA composite laminates. These factors and their impacts are shown in Figure 4, with an emphasis on the outcomes.…”

Pinus roxburghii needles are plentiful in the Himalayas and may be processed into a natural fibre. In this research, polylactic acid composites were made, including both untreated and treated Pinus roxburghii fibres as reinforcing materials. The Pinus roxburghii fibres were produced by subjecting the Pinus roxburghii needle to an alkali treatment with a 5% sodium hydroxide solution in water, and the Pinus roxburghii fibres were obtained by a water retting extraction method. Pinus roxburghii fibre–polylactic acid composites were made using a compression moulding process. Composites were fabricated utilizing treated and untreated Pinus roxburghii fibre with fibre loadings of 20%, 30%, and 40% by weight. Subsequently, the investigators examined the alterations in the tensile, flexural, impact, and morphological properties with sodium hydroxide treatment. As expected, alkaline treatment considerably boosted the compatibility between Pinus roxburghii fibre and polylactic acid, leading to improvements in the morphological, hardness, and mechanical characteristics of Pinus roxburghii fibre composites. In addition, when 30 wt.% of treated fibres were used, the mechanical characteristics improved.

“…The primary oxides present in Basalt fiber are SiO 2 (44-47 wt.%), Al 2 O 3 (11-13 wt.%), CaO (10-12 wt.%), and MgO (8-11 wt.%), while other oxides constitute less than 5 wt.%. 25,26 In the process of designing machine component it is crucial to decrease the resonant amplitude, the level of modal damping that accompanies each mode of structure affects the resonant amplitude. Generally, natural fiber reinforced composites (NFRCs) have high damping capabilities than metal matrix composites.…”

This study emphasize on the fabrication and testing of Grewia optiva/Basalt fiber reinforced polymer composites for use in internal applications of automobiles and aircraft. The study investigates the use of Grewia optiva fiber (local plant based fiber) with Basalt fiber, where chopped Basalt fiber (6, 9, and 12 mm) is reinforced in polyester matrix in combination with Grewia optiva fiber. Composite test specimen are fabricated and analyzed using a smart actuation system to evaluate the free vibrational behavior of the composites experimentally. The impact of various parameters including length of the fiber and its weight percentage on the free vibrational behavior of composites is determined. The percentage of individual reinforced fiber is varied (0, 4, 8, and 12 wt.%) maintaining fiber weight % constant, that is, 12 wt.% of composite. The experimental results help to identify the variations in natural frequencies of Basalt/Grewia optiva fiber based composites. B12/GO0 demonstrate the natural frequency of 67 Hz and 44.71 MPa tensile strength for 12 mm fiber reinforced composites. The finding from this experimental work provide insights into the potential applications of Basalt/Grewia optiva fiber reinforced composites for automobile and air craft industries.
