The use of agricultural by-products in the production of biocomposite materials is of growing interest worldwide. Mechanical properties and degradation temperature of a biocomposite depend strongly on the characteristics of the selected reinforcement. The present study focuses on the characterization of three lignocellulosic agro-industrial wastes: olive wet husk (OWH), olive pits (OP) and grape stalks (GS), generated by industries of Cuyo region in Argentina. Such characterization comprises: proximate analysis, lignocellulosic composition, functional groups, crystalline phases, mineralogical and elemental composition, and thermal properties. The results obtained are of relevance for understanding the final properties of the biocomposites that will be prepared with these lignocellulosic particles, and will allow to determine which of them is the most appropriate for a specific application. This work suggests that OP could have better interfacial interaction with a polymeric matrix.

生物复合材料：农业工业废料能否用作聚合物的增强材料？

在生物复合材料的生产中使用农业副产品越来越受到全世界的关注。生物复合材料的机械性能和降解温度很大程度上取决于所选增强材料的特性。本研究的重点是阿根廷库约地区工业产生的三种木质纤维素农业工业废物的表征：橄榄湿壳 (OWH)、橄榄核 (OP) 和葡萄茎 (GS)。这种表征包括：近似分析、木质纤维素组成、官能团、结晶相、矿物学和元素组成以及热特性。获得的结果对于理解将用这些木质纤维素颗粒制备的生物复合材料的最终特性具有相关性，并允许确定它们中的哪一个最适合特定应用程序。这项工作表明 OP 可以与聚合物基质具有更好的界面相互作用。
