abstract = "The manufacturing and application of biocomposites are remarkable achievements in replacing conventional non-biodegradable materials. In general, biocomposites are made up of biopolymers and bio-based reinforcing agents. Biofibres are also the main constituents of biocomposites, which are generated from biological entities such as crop fibres (cotton, flax, mycelium of fungi, hemp), recycled wood, wastepaper, agro-based by-products or regenerated cellulose fibre. In this paper, a mould intended for biocomposites based on mycelium and an adequate substrate is tested. The primary purpose of the mould is to bring the loose natural material into a solid preparation following the standards ASTM D7250 and ASTM D1037, which include testing the technologically prepared and hardened sample for tensile and pressure. Development and moulding of biocomposite are the technological processes of drying after sowing mycelium so that a variant of the mould with a perforated upper part was used to harden the samples thoroughly. In the mould, realization is used PLA thermoplastic filaments. Mould was made as an assembly of two parts, and its shape is like a dog bone, according to the mentioned standards. This polymer enclosure is helpful for other biocomposite structures (a mixture of different fungi species and adequate substrates)., Proizvodnja i primena biokompozita je značajno doprinela smanjenju upotrebe nebiorazgradivih materijala. U opštem smislu, biokompoziti se sastoje od biorazgradivih prirodnih polimera (biopolimera) i ojačavajuće faze-biovlakana. Biovlakna su glavni sastojci ovih materijala i mogu biti različitog prirodnog porekla (pamuk, lan, konoplja, micelije gljiva, reciklirano drvo, agroproizvodi ili regenerisana celulozna vlakna). U ovom radu, testiran je i razvijen kalup za biokompozite na bazi micelijuma i odgovarajućeg supstrata (pšenične slame). Osnovna namena kalupa je priprema i očvršćavanje bio materijala da bi bilo omugućeno ispitivanje u skladu sa standardima ASTM D7250 i ASTM D1037, koji su namenjeni ispitivanju uzoraka na istezanje i pritisak. Izrada i
oblikovanje biokompozita predstavljaju tehnološke postupke koji se sprovode u cilju sušenja i smanjenja procenta vlage nakon zasejavanja, pri čemu je gornji deo perforiran zbog isparavanja i što boljeg očvršćavanja uzoraka. Za proizvodnju kalupa upotrebljen je PLA termoplastični filament.
Kalup je izrađen kao dvodelni sklop, oblika “dog bone” u skladu sa pomenutim standardima.
Ovako pripremljen i sklopljen kalup je moguće primeniti i za ispitivanje ostalih biokompozitnih
struktura (mešavina različitih vrsta fungi i odgovarajućih supstrata).",
