Embodiment 1
[0059] Example 1: Injection Molded Composite Parts Using the Size Composition of the Invention
[0060] The sizing formulations shown in Table 2 were prepared in buckets as outlined below. To prepare the size composition, 90% water and silane coupling agent were added to a bucket to form a mixture. The mixture is then stirred for a period of time to hydrolyze the silane. After hydrolysis of the silane, a film former is added to the mixture with stirring to form a size composition. The size composition was then diluted with the remaining water to achieve a target mixed solids of 6.0% mixed solids.

[0071] Example 2: Compression-molded composite parts using the sizing composition of the invention
[0072] The sizing formulations shown in Table 4 were prepared in buckets following the outline instructions below. To prepare the size composition, 90% water and silane coupling agent were added to a bucket to form a mixture. The mixture is then stirred for a period of time to hydrolyze the silane. After hydrolysis of the silane, a film former is added to the mixture with stirring to form a size composition. The size composition was then diluted with the remaining water to achieve a target mixed solids of 6.0% mixed solids.
