<dc:description xml:lang="pl"><![CDATA[Polymeric composites are increasingly used in orthopedic devices due to their high strength-to-weight ratio. However, machining, particularly drilling, remains a challenge because of high material costs and insufficient studies of drilling-induced damage in carbon-orthocryl composites. This study examines the mechanical behavior and micro-damages associated with drilling in prosthetic socket materials.]]></dc:description>
<dc:description xml:lang="pl"><![CDATA[Specimens 3mm thick were produced by infusion moulding and tested using static tensile and Charpy impact tests, followed by scanning electron microscopy (SEM) for damage characterization. Drilled specimens revealed a 29.64% higher elastic modulus compared to conventional ones, while their ultimate tensile strength was 17.42% lower. The average impact toughness was measured at 0.075 J/mm2.]]></dc:description>
<dc:description xml:lang="pl"><![CDATA[SEM analysis revealed various degradation modes, including resin breakage, fiber rupture, intralaminar, translaminar, and interlaminar delamination, with poor resin-fiber wetting identified as a key defect. These results fill a gap in understanding the machinability of carbon-orthocryl composites and provide practical insights into improving molding techniques, notably increasing the amount of retarder, providing a pathway for enhancing carbon c-orthocryl socket machinability for drilling.]]></dc:description>
