The quest to discover more and to enhance the qualities of agro-residue for use as natural reinforcement of polymers continues to attract the attention of researchers because of the environmental friendliness. Hyphaene thebaica also known as doum palm is a fruit tree native to the Nile in Egypt and found in abundance in many parts of Africa. Doum palm fruit contains probably the hardest and toughest known nut. The doum palm nuts (DPN) are the most under-used hard-nut despite their abundance in nature. This study presents the potential doum palm nut particles (DPNp) as natural reinforcement for high density polyethylene (HDPE). Properties of DPN such as density, hardness and weight loss due to heating were determined. HDPE/DPNp composites were produced by reinforcing HDPE with 30, 35, 40 and 45% DPNp particles of two different sizes. The particle sizes 600 μm and 710 μm led to classifying the composites as X-composite and Y-composite respectively. The static and dynamic mechanical properties of the composites were determined and compared with the those of pure HDPE. Results showed that HDPE and DPNp can be formed into light and attractive components. Loading HPDE with DPNp significantly improve static mechanical properties of HDPE such as tensile strength, hardness, stiffness and resistance to impact failure by 50%, 200%, 800% and 1500% respectively. The HDPE/DPNp composites also had better dynamic mechanical properties. The ability of the composites to maintain load bearing capacity under dynamic conditions was superior to that of HDPE.

“…It is observed in Figure 8 that the Vickers hardness values of the HDPE/DPNp composites increased steadily with increased DPNp loading. This shows that hardness is proportional to relative fiber volume [10] [11].…”

“…Then, the required amount of 40 mm sized fibres was randomly oriented in the mould cavity and subjected to the precompression for about 20 to 30 minutes for making a fibre mat. İn a first step, the polyester matrix was prepared with 1.5 ml of each MEKP, cobalt naphthenate and 100ml of the polyester matrix for the room temperature curing (Pokhriyal et al 2017). During the mixing process, the catalyst was thoroughly mixed or added in the polyester matrix before the accelerator.…”

“…The maximum tensile strength was found in the C10 composite, which is 47.83 MPa. Pokhriyal et al (17) reported that the tensile strength of nettle fibre (15% loading) polyester composite is 31.39 MPa. It has been seen from figure4, that the elongation at break for composite C2 to C5 does not show any trend.…”

In the present work, an in-house centrifugal casting setup was developed in the laboratory. Waste natural fillers such as soap nuts seeds, Aegle marmelos, and Terminalia chebula were used for the preparation of polyester based composite by using centrifugal casting technique. The influence of filler loading (3%, 6%, 9% and 12% by weight) on the physical-mechanical behaviour of hybrid composites has been performed. The moisture absorption tests were conducted according to the ASTM D 570-98 standards. Hybrid composites with varying composition of polyester, Aegle marmelos, Terminalia chebula, and soap nut seed were fabricated. It has been observed that the maximum water absorption was in the range of 0.23% to 2.12% (weight fraction), the maximum tensile strength 47.83 MPa, hardness 71VH and impact strength 5.8 Joule for the hybrid composite material with 12 wt% Aegle marmelos, 9 wt% Terminalia chebula, 6 wt% soap nuts seed. The minimum specific wear rate (0.00196 mm 3 /Nm) was obtained for the composition of 12 wt% soap nuts seed and 3 wt% Aegle marmelos.
