Abstract
The invention relates to a method for obtaining an article formed of a thermoplastic matrix, said method providing for formulating inputs comprising at least one source of thermoplastic material and at least one source of filler; mixing and grinding said inputs; thermocompressing said ground mixture to obtain the article; the source of thermoplastic material being formulated so as to comprise a quantity QLM of thermoplastic material LM having a melting temperature TLM below 150° C. and a quantity QHM of thermoplastic material HM having a melting temperature THM above 180° C., the thermocompression temperature being higher than the melting temperature TLM.
Claims17
A method for obtaining an article formed of a thermoplastic matrix, said method providing for:
- formulating inputs comprising at least one source of thermoplastic material and at least one source of filler;
- mixing and grinding said inputs;
- thermocompressing said ground mixture to obtain the article;
- said method being characterized in that the source of thermoplastic material is formulated so as to comprise a quantity QLM of thermoplastic material LM having a melting temperature TLM lower than 150° C. and a quantity QHM of thermoplastic material HM having a melting temperature THM higher than 180° C., the thermocompression temperature being higher than the melting temperature TLM.
