You can't do this as a simple function.  You either need an extension 
function or recursive named templates.

If you know the string in advance, you could use a substring:

substring('abcabcabcabcabcabcabcabcabcabcabcabcabc',3*3)

But the named template is the most general solution:

<xsl:call-template name="replicate">
   <xsl:with-param name="string" select="'abc'"/>
   <xsl:with-param name="num" select="3"/>
</xsl:call-template>

<xsl:template name="replicate">
   <xsl:param name="string" select="''"/>
   <xsl:param name="num" select="1"/>
   <xsl:value-of select="$string"/>
   <xsl:if test="$num &gt; 1">
     <xsl:call-template name="replicate">
       <xsl:with-param name="string" select="$string"/>
       <xsl:with-param name="num" select="$num - 1"/>
     </xsl:call-template>
   </xsl:if>
</xsl:template>
