Effects of particle size, particle/matrix interface adhesion and particle loading on mechanical properties of particulate–polymer composites

Composites are materials which synergically combine properties of each phase – matrix and filler. Polymer materials can be used as matrix while inorganic and organic particles can be used as fillers. Composite systems based on renewable resources can be designed as an interesting material for engineering. This paper describes on the tribological and other mechanical properties of biocomposites based on polymer resins and microparticles - seed cakes, which were obtained from seeds of the plant Jatropha Curcas L. during pressing. The particle size obtained was 573 µm.The results confirmed that the epoxy and polyurethane resins were capable of forming which corresponds to the interaction with the organic particles prepared from the seeds of Jatropha Curcas L. The presence of particles however, changed the mechanical properties of the resins. In the case of epoxy resins and polyurethane (Sika Force 7723), the hardness according to Shore D identically decreased with a maximum of 1.9. Abrasion resistance decreased due to the presence of particles of 0.0393 cm3 for Glue Epox Rapid, 0.0449 cm3 for Epoxy 1200/324 and 0.0567 cm3 for Sika Force 7723.

Coir Pith

This study aimed to find out the feasibility of coir pith as a raw material for particleboard production. Considering particle size, an attempt was taken to produce resin bonded coir pith particleboard and binder-less coir pith particleboard as well. The physical and mechanical properties of the board were examined. The particleboard made from medium size particle showed the best performance in aspect of properties. The particleboards made with 16% Melamine Urea Formaldehyde (MUF) had better product quality than binder-less coir pith board. The MOR, MOE, TS and IB were respectively 24.65, 2398, 22.55 and 1.52 N/mm2. Coir pith board may be a sustainable, cheap and durable building and packaging materials and timber substitute.Bangladesh J. Sci. Ind. Res. 51(3), 239-245, 2016
