I know that there has been some developmental work done looking at using 30% glass fibre filled PPS (polysulphone). I believe the idea is to use plastic injection moulding + gas injection to mimic the structure and weight of an actual hip joint. However, I am not aware of any published research on this front.

Dear Rafael and list,
I'm not an expert in orthopaedic surgery but as far as I know you cannot
make an artificial hip joint from anything non-metallic. Acrylic (double
processed PMMA) is sometimes used in craniofacial reconstruction but these
tend not to be physically load bearing, certainly no where near the kind of
loads a hip joint would be expected to undergo.
Although many artificial hip joints incorporate ceramic and plastic bearing
surfaces the main parts are either titanium or a medical grade of stainless
steel.
I am also curious as to why you want a non-metallic artificial hip joint? I
have seen hip replacement surgery first hand and there's no way I'd have
anything less than top quality metal work if it were me under the knife!
regards,
Richard
