The wide dispersion of the properties plant fiber bundles further limits their use. In this study, manual and retting methods were used to extract from available underutilized Ananas comosus (AC) leaf waste in Cameroon. These fibers sampled three zones: base, middle head. extracted by different zones found have better thermal stability. A 2.5% solution sodium hypochlorite was for bleaching various pineapple fibers. Density, fineness, functional groups, mechanical properties, water absorption...
Quasi-static tensile tests are commonly used to determine the mechanical properties of fiber bundles. These generally carried out at a low standard speed 1 mm.min−1, which is recommended for elementary fibers, although other moderate and high speeds rarely used. In this study, were on coir sisal bundles from coastal region Cameroon using four different speeds: 1, 2, 5, 10 mm.min−1 assess properties. Samples prepared by attaching two ends each randomly selected bundle paper frame obtain...
Identifying the potential of new bast fibres is a solution for diversifying biobased reinforcements and replacing environmentally harmful synthetic fibres. In this study, were extracted from Megaphrynium macrostachyum stems by biological chemical retting. The bleached with 2.5wt% sodium hypochlorite (NaClO) solution. biological, analysed chemical, morphological, physical, mechanical thermal point view. possibility using these as reinforcement in gypsum-based biocomposites construction was...
Tropical Triumfetta cordifolia (TC) fibre extracted from the equatorial region of Cameroon has been characterized as a potential for textiles. An investigation extraction parameters to soften this is crucial use it biobased material in spinning process. To obtain textile quality fibres, 34 sodium hydroxide tests were carried out study effect conditions on its characteristics. Thus, three levels concentrations (0.5, 1.0 and 1.5 wt%), temperatures (80, 100 120 °C) durations (120, 180 240min)...
In an attempt to increase biodiversity in natural plant fiber nonwovens, new sources of fibers must be discovered. Nonwoven fabric is a promising commercial product for upgrading the bast Triumfetta cordifolia (TCF) and giving it opportunity used composite nonwoven applications. Two types TCF mats blended with polylactide one polypropylene other at mass ratio 50 : were manufactured using carding needling technology. The aim present work compare different TCF-based nonwovens based on fibers,...
This paper aims to determine the technical feasibility of introducing <i>Neuropeltis acuminatas</i> fibers into polymer matrix composites. The Young's modulus polyester without reinforcement is higher than that containing fibers. are good candidates for reinforcing resin results three-point bending tests enabled us compare moduli as a function orientation between different ratios. For unidirectional orientation, mechanical properties composite changed...
This paper focuses on the study of physical, biochemical, structural, and thermal properties plant fibres Rhecktophyllum camerunense (RC), Neuropeltis acuminatas (NA) Ananas comosus (AC) from equatorial region Cameroon. The traditional use these inspired researchers to investigated their properties. aims at improving state knowledge with a view diversifying applications. are extracted by retting. Then, apparent density was measured following ASTM D792 standard water moisture absorption...
Plant fibers are being increasingly explored for their use in engineering polymers and composites, many works have described properties, especially flax hemp fibers. Nevertheless, the availability of plant varies according to geographical location on planet. This study presents first work mechanical properties a tropical fiber extracted from bast Cola lepidota (CL) plant. After debarking step, CL were manually by wet-retting. The tensile identified experimentally at scale, analysis results...
The project consists in the implementation of a biocomposite based on tannin resin and natural rubber matrices with bast fibres Triumfetta cordifolia A.Rich."Okong" from equatorial region Cameroon as reinforcement. A study this still little known fibre is necessary. This paper evaluates physico-chemical mechanical characteristics fibers. fibers are extracted by us. series experiments conducted for purpose: morphological observation scanning electron microscope (SEM); density evaluation...
This article contributes to the development of new class fully biodegradable "green" composites by combining fibers (natural/bio) with resin. The vegetable (Triumfetta cordifolia and sugarcane bagasse) treated NaOH bleached were incorporated into a natural rubber matrix. influence fiber ratio on physical properties, tensile strength surface hardness hybrid was analyzed. results show that addition in matrix increases water absorption capacity but gradually reduces it increasing ratio....
This study represents the first works on manufacture of reinforcements for composite applications such as yarns and fabrics using a tropical fiber extracted from bast Cola Lepidota (CL) plant. Different types products were produced, including twisted untwisted woven quasi-unidirectional to samples. At each scale, experimental characterizations textile mechanical properties carried out; these are compared those given in literature concerning natural materials. The results show that tenacity...
This study examines the implementation and characterization of a polymer matrix composite material reinforced by sugarcane residues.
