Proposal titleImprove abrasion properties and increased useful life of UHMWPE* hip and knee

prothesis, using electron beam irradiation.

AbstractThe objective of the Craft project is to improve the mechanical characteristics, mainly the

ABRASION resistance of UHMWPE*, a material fully tested for its use in prothesis, by

optimising a new cross-linking process: electron beam irradiation. The SME proposers

are interest on industrially exploit the results of the RTD project. The use of lighter and

inert materials in prothesis, with mechanical properties similar to metals has become known

over the lastyears. The range of materials which fulfil these requirements is very limited,

but have been evolving with time, now using metal combined with plastic or plastic

prothesis. UHMWPE* is one of the materials which best fulfils these requirements, and is

the most widely used in its category. However ithas inherent chemical problems, such as its

limited abrasion resistance, which generates abrasion problems and can cause problems

such as osteolysis, reduced mobility;..... not desirable in human body. Research carried out

in this area over the last five years has enabled improvements in abrasion resistance, but

they have notreached totally satisfactory solutions. The objective of this project is to

reduce abrasion to practically zero in UHMWPE* hip and knee prothesis, by electron beam

irradiation of the material. This technique is based on a clean energy, unlike gamma

radiation (the most commonly used...
