Ho, Mei-Po and Lau, Kin-tak and Wang, Hao and Bhattacharyya, Debes (2011) Mechanical properties of an injected silk fibre reinforced PLA composite. In: 19th International Symposium on Processing and Fabrication of Advanced Materials (PFAM XIX), 14-17 Jan 2011, Auckland, New Zealand.
Text (Accepted Version)
Chopped silkworm silk fibres and Poly-lactic acid (PLA) were mixed to form a fully biodegradable thermoplastic composite. Injection moulding process was used to mix these constituents together at a controlled temperature range. The mechanical properties of the composite were examined through tensile and flexural property and Izod impact tests. It was found that the Young's and flexural moduli of the composite increased while their strengths and impact resistance decreased during the tests as compared with a PLA sample. Early fibre fractures observed from micrographs explain the reasons of enhanced moduli and reduction of strengths.
