W artykule zostały opisane kompozyty wytworzone na osnowie całkowicie biopochodnego poliamidu 10.10 wzmocnionego zmielonymi łupinami orzecha włoskiego w ilości masowej 10% oraz 30% jak również kompozyty z dodatkiem 30% masowej ilości włókien szklanych. Zbadano właściwości mechaniczne (wytrzymałość na rozciąganie (σt), moduł sprężystości (Et) oraz moduł sprężystości przy zginaniu (Ef) i naprężenie zginające przy naprężeniu 3,5% (σf)) wytworzonych kompozytów. Dane analizy mechanicznej wykazały, że wytrzymałość na rozciąganie oraz sztywność kompozytów po czterech latach przechowywania znacznie spadły. Jednakże zaobserwowany został niewielki spadek wartości modułu zginania na poziomie 5% w porównaniu do wyników uzyskanych dla kompozytów bezpośrednio po wtrysku. Dodatkowo w celu oceny rozkładu cząstek i adhezji napełniaczy do matrycy wykonano zdjęcia sem.
This paper presents an investigation in which bio-based polyamide 10.10 was used as a polymer matrix. Composites were reinforced in three different ways including: 10 wt% and 30 wt% of walnut shell flour as well as 30 wt% of glass fibres. The composites were prepared by injection moulding. Mechanical properties (tensile strength (σt), modulus of elasticity (Et) as well as flexural modulus (Ef) and flexural stress at 3.5% strain (σf)) were obtained. The mechanical data of analysis showed that tensile strength and tensile stiffness significantly decreased after four years of storage. Another state was noted for the bending module, where the decrease in value was at a level of 5% compared to results obtained immediately after injection. Additionally, SEM images were taken to assess the distribution of particles and the adhesion of fillers to the matrix.
