“…Ahmed et al [39] produced brake pads using watermelon peels and revealed that 25 wt% preparation (resin) matched the commercial counterpart. Achebe et al [40] produced palm kernel filled epoxy composite and reported the abrasion resistance of 1.67 mg/m. The wear resistance enhanced as the palm kernel filler content increased.…”

Wear rate appraisals are currently indispensable on agro-waste filled composites for brake pads as they predict the expected lifespan of the materials. However, existing wear rate models are inaccurate as predictions omit the inflationary cost of the materials. In this paper, the idea is to account for the inflationary cost of the materials and adjust that into a pseudo wear rate model. The wear rate of agro-waste fillers in an organic matrix to create brake pads under dry sliding wear experiments was considered. Five composite specimens were fabricated in cylindrical specimen height of 14.5 mm and varying diameters of 8, 10, 12 and 15.5 mm and the material wear loss was measured. The 8, 10 and 12 mm diameter specimens revealed that the composite with the best and worst wear resistance were the wear rates of 0.6, 1.4, 1.73 mm3/Nm, and 3.07, 3.54, 4.19 mm3/Nm, respectively. The 15.5 mm diameter specimen showed lower wear rates of 2.13 and 2.14 and 1.56 mm3/Nm than commercial brake pad’s 2.58 mm3/Nm. The pseudo wear rate model predicts the impact of the independent variable i.e. inflationary cost, opportunity cost, time, and sample size. The utility of this effort is to assist the composite manufacturers to take cost-effective decisions and design optimisation can be accomplished to lower the cost of composite products.

This work presents the use as a filler of carbonized breadfruit seed coat and recycled low density polyethylene as the binder in ceiling board manufacturing. The depulped bread fruit seed was carbonized for 2 h at a temperature of 500°C. The experimental design was set up using the Design Expert software. A total of 30 experimental tests were developed for four parameters and three responses. The parameters are carbonized bread fruit seed coat/recycled Low Density Polyethylene mass ratio (filler-binder mass ratio), compaction time, compaction temperature and compaction pressure while the responses are thermal conductivity, thickness swell and water absorption. The models developed have been validated using the Study of Variance (ANOVA). Using the 3D surface map, the influence of the parameters on the responses was studied. The optimization method of the Design Expert program was used to evaluate the optimal level of the parameters that will produce the best possible result from their combination. The result gave optimal values of 16.206% filler/rLDPE, 9.406minutes compaction time, 200°C compaction temperature and 11 MPa compaction pressure, which gave 0.246% Water Absorption, 1.998% Thickness Swell and 2.898 W/M.K Thermal Conductivity.

A brake pad has been developed employing a hybrid of cane wood and palm fruit fibre as filler material. The filler materials were extracted and processed; however, the palm fruit fibre was further treated with NaOH to remove oil remnants. After proper drying, the filler materials were ground and sieved into 150 µm particle size. The experimental design was set up using Central Composite Design in Design Expert software. The design varied the percentage composition of the filler materials and the binder. At constant press time of 8 min, press temperature of 160 ℃ and curing time of 2 h, 20 test samples were produced and tested for mechanical and physical properties. These include hardness, wear rate and water absorption. The Fourier transform infrared analyses showed that both cane wood and palm fruit fibres have active alcohol (O–H) and amine (C–N) functional groups. The experimental results were analysed and optimised using response surface methodology and validated using the analysis of variance tool of the Design Expert software. An optimal 30% resin, 3.48% palm fruit fibre and 6.52% cane wood composition by mass was developed, which gave a product with 98.25 MPa hardness, 4.13 mg/m wear rate and 0.494% water absorption. This result indicated that hybridised cane wood–palm fruit fibre is a good filler material for brake pad production.
