\subsection{Panels}
\begin{enumerate}
\item FACC panels:
\\
Measured: 
\\
\hspace{1cm}
914 $\pm$ 50~g/m$^2$ (based on 4 samples of $\sim 20cm^2$)
\\
\hspace{1cm}
892 $\pm$ 30~g/m$^2$ (based on 2 panels, 2m x 0.13m)
\\

Expected: 
\\
940g/m$^2$ (Prepreg: 360g/m$^2$, HC 480g/m$^2$, glue 100g/m$^2$)
\\
\item ADCO panels:
\\
Measured:\\
1261 $\pm$ 30~g/m$^2$ (based on 2 panels, 2m x 0.13m)

\end{enumerate}
\subsection{Fibre mat (before casting)}
Measured: 
\\
\hspace{1cm}
1223 $\pm$ 20~g/m$^2$ (based on a sample of $\sim 250cm^2$ from Aachen 7cm wide module)
\subsection{Fibre mat (after casting)}
Measured:
1512 $\pm$ 20~g/m$^2$ (based on a sample of $\sim 40cm^2$ from a casted 13cm wide Dortmund mat)
\\
Difference: 289~g/cm$^2$ \\
Expected 250~g/cm$^2$ for a 0.25mm thick layer of glue.
