Elaboration and Characterization of a Composite Material Based on <i>Canarium schweinfurthii</i> Engl Cores with a Polyester Matrix

Abstract

The aim of this work was to develop and characterize a polyester matrix composite material based on Canarium schweinfurthii Engl core granule. The particle size and the mass fractions of these cores used as fillers in this composite were the two optimization parameters. The experimentation of the twelve sample areas was based on the following optimization parameters: Three particles sizes of 80 < T 1 < 160 µm, 160 < T 2 < 315 µm and 315 < T 3 < 630 µm and four mass fractions of 0%, 40%, 45% and 50%. The composites were produced by hand lay-up method. The physical and mechanical parameters concerned by this study are: absolute density, compressive stress at break, Young's modulus in bending and coefficient of static friction with wood. Each of these parameters was determined by testing ten specimens per sampling area. It was found that the absolute density varies very little as a function of particle size and mass fraction. This absolute density is between 1200 and 1232 kg·m −3 , which allows us to admit that this composite belongs to the family of light materials. The maximum compressive stress at break was obtained for the formulation 40% filler of size T 3 . This compressive stress at maximum rupture is in the range of 199.14 MPa. From 0% to 45% of filler, the flexural Young's modulus of the composite increases whatever the particle size. The highest value is obtained for T 2 particle size, i.e. 13.11 GPa. The static friction coefficient of the composite on wood increases as the filler con-How to cite this paper: Ndapeu

Physical, Water Diffusion and Micro-Structural Analysis of “Canarium Schweinfurthii Engl”

“…Most papers have reported the development of activated charcoals based on CS kernels (Figure 1(c)) [9] [10] [11] for use as an absorbent in filters for copper II ions and other heavy ions. Recent work is indeed interested in using CS aggregates as a filler for composite materials [12].…”

“…(2019) focused their study in the predicting of suitable water absorption of global C.S pulp fruit at three different temperatures (35˚C, 50˚C, 65˚C) [14]. Very few or no researchers have so far focused on the CS core (Part 1 Figure 2) which could be a material with interesting properties for the particle composite industry [12]. It is therefore interesting to study the intrinsic properties of this by-product in order to consider its use.…”

Influence of temperature on the creep behaviour by macroindentation of Cocos nucifera shells and Canarium schweinfurthii cores (bio-shellnut wastes in Cameroon)

“…CN and CS biomaterials can be used alone, such as timber for construction and structural purposes [13,[29][30][31][32]. But their most extensive use is achieved with composites, in the forms of reinforcements within a matrix of either polymer [1, 2, 5-7, 12, 14, 15, 29, 33-36], ceramic [1,5], metallic [1,5,37], or hybrid type [5,7,8,11,16,17].…”

“…In the case of CS, technical applications as a composite material lead to characterization approaches that are similar to those already mentioned for CN, with the enhancement of the effect of density, the water absorption rate, and friction properties [29,35]. Recent work has focused on producing brake linings by combining CS fillers and palm kernel fiber with urea formaldehyde resin.…”

“…Recent work has focused on producing brake linings by combining CS fillers and palm kernel fiber with urea formaldehyde resin. He was interested in the effect of input size and proportions on composite density and dynamic friction coefficient [39]. Standard mechanical characterization can also be carried out for parts of CS when they are in their natural state, such as strength and stiffness [32] or strength and mobility for nuts, the humidity level being an important parameter in the latter case [40].…”
